15:16 < philippejadin> hello, fellow hardcore irc users !
15:16 < se6astian> ;)
15:19 < se6astian> maybe we can have a soft revival of IRC
15:19 < Bertl> hey philippejadin!
15:19 < se6astian> now that the NSA is managing our inboxes and logging our hangouts ;)
15:20 < se6astian> May I introduce, Philippe from Belgium and Bertl from yesterday evening ;)
15:20 < Bertl> I'm the one to blame for the sudden interest in irc :)
15:20 < se6astian> yes, its all his fault
15:21 < Bertl> I've heard that folks around the world are interested in axiom related development, and I thought it might be beneficial to virtually come together somewhere ...
15:22 < Bertl> and as I hang out on IRC anyway ...
15:36 < philippejadin> Good idea
15:36 < philippejadin> hello !
15:37 < philippejadin> it reminds me when I was on the worldforge.org project
15:37 < philippejadin> I spent hours on irc
15:37 < philippejadin> huge time sucker tool
15:37 < philippejadin> but great fun
15:46 < philippejadin> So, Bertl, what do you intend to work on ?
15:51 -!- dmj_nova [~david@c-50-141-244-238.hsd1.il.comcast.net] has joined #apertus
15:51 < dmj_nova> hello all
15:53 < philippejadin> hello !
15:55 < se6astian> hurray, more people, hi david!
15:56 < Bertl> welcome dmj_nova!
15:59 < dmj_nova> se6astian: I'm checking on the possibility to get the zedboard with academic pricing
15:59 < se6astian> perfect

15:59 -!- philippejadin1 [~jadin-02@193.191.228.254] has left #apertus []
15:59 < se6astian> here it was no problem at all, they didnt even need any proof after I sent them a mail from my .edu address
16:00 < dmj_nova> from diligent's site?
16:00 < philippejadin> the .edu address is alreadya good proof :-)
16:01 < se6astian> I found an austrian distributor
16:07 < dmj_nova> Hmm...I suppose such a board could be used as an embedded computer and control system for nanomoco boards
16:08 < dmj_nova> And therefore be "required" for my independent study
16:08 < se6astian> definitely!
16:08 < se6astian> :)
16:13 < dmj_nova> zedboard can run ubuntu, right?
16:14 < Bertl> philippejadin: well, I'll be investigating our FPGA options, and I'm currently trying to collect information about the components and adapter PCB 
16:14 < se6astian> Bertl, this could be usefull later: http://blog.aeste.my/2013/05/09/zedboard-on-ubuntu-12-04-lts/
16:14 < philippejadin> dmj_nova: yes
16:14 < philippejadin> but you might prefer a lighter distribution
16:15 < dmj_nova> philippejadin: yep, then I can definitely use it for my independent study
16:15 < philippejadin> (or realtime)
16:15 < Bertl> yeah, while ubuntu is probably nice for desktop, it's overkill for embedded systems
16:15 < dmj_nova> philippejadin: mostly care since it avoids having to port tons of dependencies
16:15 < Bertl> (which can be easily seen on raspberry pi :)
16:16 < Bertl> but probably a good starting point anyway
16:16 < dmj_nova> and if I want to do fun things with realtime collaboration
16:16 < philippejadin> I hav eno experience with realtime linux, but for our use it might be interesting
16:16 < dmj_nova> *cough*dmedia integration*cough*
16:17 < Bertl> philippejadin: there is hard realtime and soft realtime ... basic realtime support is already present in almost all recent linux kernels
16:18 < Bertl> i.e. you can utilize the realtime sheduler for example
16:18 < philippejadin> the idea anyway is to do the hard processing on the fpga and use linux for not so realtime menu overlay. I hav eno idea when we'll have to write files somewhere how we'll do that :-)
16:19 < dmj_nova> I expect that we'll want to do all the stuff that needs to be hard realtime in the FPGA
16:19 < Bertl> most likely, at least to the extend possible
16:20 < Bertl> philippejadin: you mean the actual data from the sensor or what?
16:20 < dmj_nova> the FPGA could likely output frames to memory that's shared with Linux and the Linux can read and store it as appropriate
16:21 < Bertl> ala dual ported ram?
16:21 < dmj_nova> assuming our hardware can do that
16:22 < Bertl> we'll see, no idea atm ...
16:22 < philippejadin> Wild guess : image processing -> fpga / writing images to disk -> linux (as long as it can be done fast enough)
16:22 < dmj_nova> What is everyone's FPGA experience?
16:23 < Bertl> I've started recently with FPGAs mainly because I got my hands on a bunch of really cheap lattice chips. I've the theory behind it and I've already managed to write a bunch of VHDL programs to play with
16:24 < dmj_nova> I programmed the game Spacewar! for an FPGA in a class, and I designed a simulated 16-bit CPU with L2 cache and basic pipelining in VHDL.
16:24 < Bertl> I have a lot of experience with embedded systems in general and I use Linux for almost everything, including design and development
16:25 < Bertl> dmj_nova: nice!
16:28 < dmj_nova> I also use Linux pretty much always.  I'm part of the team making Novacut.
16:30 < Bertl> I probably should mention that I have no experience whatsoever with making movies or filming in general, but I've done a lot of image processing (technical) and know the mathematical models 
16:30 < dmj_nova> I have some experience with (very) indie filmmaking
16:31 < dmj_nova> and quite a few contacts with filmmakers
16:31 < dmj_nova> so we should be able to get feedback when the time comes
16:31 < dmj_nova> I do have some gstreamer experience
16:33 < dmj_nova> Some of this may be a bit obvious but a few things to keep in mind since we're a distributed team on a hardware project
16:34 < dmj_nova> Keeping things modular with well defined interfaces should reduce the amount of breakage/stepping on other people's work
16:34 < dmj_nova> Bertl: have you ever worked with other people on your projects?
16:35  * philippejadin has to go, see you later guys, I'm very happy to see you on board !
16:36 < Bertl> dmj_nova: yes, I'm maintaining an open source project since 2001
16:36 < dmj_nova> Bertl: like a hardware kind?
16:36 -!- philippejadin [c1bfe4f2@gateway/web/freenode/ip.193.191.228.242] has quit [Quit: Page closed]
16:36 < Bertl> software (Linux-VServer)
16:37 < dmj_nova> okay, hardware (from my experience) tends to be a bit harder to collaborate
16:37 < Bertl> quite understandable
16:37 < dmj_nova> So modularity and not changing things at the interfaces is a pretty big deal
16:38 < Bertl> very similar to the linux kernel interface, actually :)
16:38 < dmj_nova> since (depending on your tools) merging can be a major problem
16:40 < dmj_nova> I was also talking to se6astian about the possibility of having an automated test setup to verify that our commits don't break functionality
16:41 < Bertl> automated as in physical hardware running whatever was commited?
16:41 < dmj_nova> yes
16:41 < Bertl> sounds good
16:41 < dmj_nova> and then reporting back any issues
16:41 < Bertl> I'm all for automation
16:41 < Bertl> I hate doing things twice, I'd rather script it :)
16:41 < dmj_nova> Novacut has a test suite that runs on launchpad for every build
16:42 < dmj_nova> it's helped us catch problems and keep trunk releaseable
16:43 < Bertl> yep, we have made similar experiences with automated kernel building and testing
16:43 < Bertl> so I'm all on-board with that
16:44 < Bertl> especially as I prefer to have an automated build process to get from source to binary

19:04 < dmj_nova> So it looks like we will have to be very space conscious with the zedboard
19:05 < dmj_nova> since it only has 85k logic cells
19:07 < dmj_nova> se6astian: The actual device will be incorporating the Zynq SoC on a custom PCB, yes?
19:11 < se6astian> yes
19:13 < se6astian> do you think our logic will require more gates than we have to our disposal?
19:17 < se6astian> Elphel camera just had 19K logic cells
19:20 < dmj_nova> elphel was only HDish, right?
19:20 < dmj_nova> My guess is that the zedboard should do for development for the time being.
19:21 < dmj_nova> However, additional logic cells will be highly useful for building in more advanced functionality
19:22 < dmj_nova> as in, having a certain amount of surplus logic cells makes the system more extensible
19:24 < se6astian> what do you mean with HDish?
19:25 < se6astian> the FPGA tasks inside the Elphel camera are pretty broad, they even do jpeg compression in there
19:25 < se6astian> and if I remember correctly they still had plenty of cells left
19:25 < se6astian> and we have 4 times more available already
19:50 < Bertl> IMHO it's always good to develop on lower end hardware ... it keeps designs efficient and performant :)
20:11 < dmj_nova> Bertl: Yeah, I think the zedboard will do fine for development
20:38 < se6astian> all parts routed!
20:38 < se6astian> https://github.com/apertus-open-source-cinema/alpha-hardware/tree/master/SFE-PCB
20:48 < dmj_nova> se6astian: nice
21:06 < se6astian> I had the idea that we could try to cut a hole into the image sensor socket and PCB in the middle of the image sensor
21:06 < se6astian> and try to attach a cooling element to the sensor
21:07 < se6astian> from behind
21:15 < dmj_nova> se6astian: hmm
21:15 < dmj_nova> any idea how easy that would be to fabricate?
21:15 < se6astian> cutting 2 holes?
21:18 < dmj_nova> So we would attach a metal plate to the back of the sensor and feed 2 heat pipes into it from behind?
21:21 < Bertl> does it require additional cooling?
21:22 < dmj_nova> I know that other cameras require careful consideration of cooling needs
21:22 < se6astian> not "require" - but noise increases with temperature
21:22 < dmj_nova> hmm...We might want to put quite some effort into cooling then
21:23 < dmj_nova> especially since our "competitors" are putting forth some very impressive devices noise-wise
21:24 < se6astian> well its just a prototype
21:24 < se6astian> but my idea was that some tests couldnt hurt
21:24 < dmj_nova> well, the prototype noise is *less* important
21:25 < se6astian> since the SFE goes directly on top of the zedboard we dont have much space between them
21:25 < dmj_nova> but testing is always good
21:25 < dmj_nova> and the final model should be designed to be usable in hot conditions for extended periods
21:30 < Bertl> we do not even know how the socket looks like (yet), so it might or might not be possible to do direct cooling
21:31 < Bertl> in general, I think it would be a lot better to use extra thick copper for the final board and vias to cool from behind
21:32 < Bertl> (if the socket allows for that)
21:33 < Bertl> alternatively, to reduce dark current and silicon noise, we could use a peltier element
21:33 < dmj_nova> so the board becomes effectively a heat spreader?
21:33 < Bertl> the area below the sensor, yes
21:33 < dmj_nova> yeah, I was thinking peltier might be a good (optional) element to use
21:33 < dmj_nova> at least when lots of power is available
21:34 < dmj_nova> but you still have to dissipate the heat outside the box one way or another
21:34 < Bertl> the question is how much heat the sensor itself will produce
21:35 < Bertl> if there isn't much heat to dissipate, a low power peltier element could keep it at very low temperatures
21:36 < Bertl> but I think, atm, we do not have enough information available
21:36 < dmj_nova> hmm...does the sensor have a temperature sensor?
21:37 < Bertl> yes
21:37 < Bertl> 16bit, digital
21:37 < dmj_nova> that should help in tuning things if there is a peltier or other active cooling system
21:37 < Bertl> yup
21:38 < dmj_nova> and compensate somewhat for lower battery performance in cold weather
21:38 < dmj_nova> not having to spend as much power on cooling
21:38 < Bertl> the CMV12000 has a total consumption of 1900mW
21:38 < dmj_nova> hmm
21:38 < Bertl> so roughly 2W max
21:39 < dmj_nova> That's not a huge amount
21:39 < dmj_nova> not trivial though
21:39 < Bertl> not sure how much is dissipated as heat though
21:39 < dmj_nova> all of it
21:40 < dmj_nova> seeing as it's not a light bulb
21:40 < dmj_nova> or a radio transmitter
21:40 < dmj_nova> or a speaker
21:41 < Bertl> yeah, but it drives outputs
21:42 < dmj_nova> true, though I expect that's minimal compared to what it consumes for its own operations
21:43 < dmj_nova> I could be wrong though
21:43 < dmj_nova> Bertl: do you have a zedboard yet?
21:46 < Bertl> yes, I got one, I'm currently preparing my development environment
21:47 < dmj_nova> cool
21:47 < dmj_nova> btw, is the software windows-only or does it support better systems?
21:47 < Bertl> I'm on linux, so it will be better than windows :)
21:48 < dmj_nova> cool, good to know it works on linux :)
21:48 < dmj_nova> much less annoying
21:48 < Bertl> definitely ... I avoid windows and microsoft products completely
21:48 < dmj_nova> well, as long as it doesn't suck as much as mentor graphics
22:01 < dmj_nova> I'm pretty sure that my windows box is both 6 months out of date and very secure against online hacks
22:04 < dmj_nova> but that's just cause it's not been turned on in that long :P

13:50 < Bertl> morning folks!
14:09 < s3bastian> hello!
14:09 < s3bastian> long night again? ;)
14:12 < Bertl> as usual!
14:27 < s3bastian> and how far did you get with the zedboard?
14:45 < Bertl> well, I got the development environment up and running and I managed to re-build the demo project
14:46 < Bertl> I'm now trying to reduce the build process to the minimum required steps to build something useable
14:53 < s3bastian> nice
14:54 < s3bastian> I forwarded you Gabes email, could you be so kin d to reply to him what you did to avoid/solve the problem he had?
15:00 < Bertl> sure
15:03 < Bertl> ah, I see, well, I'm not yet connecting via jtag to the board
15:04 < Bertl> but I will check this out soon as well, so I'll try to answer that when I get there
15:45 < s3bastian> great

17:17 < Bertl> okay, jtag via digilent via ftdi is working :)
17:18 < Bertl> I have to run in a few minutes, but I describe the process here, will write something up for the wiki later
17:18 < Bertl> I downloaded the following packages:
17:18 < Bertl> digilent.adept.runtime_2.13.1-x86_64.tar.gz
17:18 < Bertl> digilent.adept.utilities_2.1.1-x86_64.tar.gz
17:19 < Bertl> libCseDigilent_2.4.3-x86_64.tar.gz
17:19 < Bertl> (for x86 you want the 32bit versions)
17:20 < Bertl> then I installed the runtime (tar xzf digilent.adept.runtime_2.13.1-x86_64.tar.gz; cd digilent.adept.runtime_2.13.1-x86_64; ./install.sh)
17:20 < Bertl> and here is the important part: _and_ the ftdi driver
17:21 < Bertl> (cd ftdi.drivers_1.0.4-x86_64; ./install.sh)
17:21 < Bertl> then the utilities (same as runtime)
17:22 < Bertl> at this point, 'djtgcfg enum' should show the board
17:23 < Bertl> note that you need to fix the udev rules, restart udev and unplug/replug the usb-jtag to get the driver (ftdi_sio) unloaded and the permissions for the usb device changed
17:24 < Bertl> the libCseDigilent_2.4.3-x86_64.tar.gz contains two files in ISE14x/plugin which need to be copied to the ISE plugin directory
17:24 < Bertl> after that, the following should work:
17:24 < Bertl> xmd
17:24 < Bertl> connect mb mdm -cable type xilinx_plugin modulename digilent_plugin
17:26 < Bertl> http://pastebin.com/SNrfBqb9
17:26 < Bertl> of course, the default image has no mdm IP

12:46 < dmj_nova> morning :)
12:46 < dmj_nova> my zedboard should be arriving in a couple days
12:47 < Bertl> nice!
12:54 < dmj_nova> then I can get to setting up my dev environment and get started.
13:05 < Bertl> if you are going to develop on linux, let me know if you have any problems with the setup
13:06 < dmj_nova> Yeah, I'm planning on using my Ubuntu 13.04 box for development
13:26 < dmj_nova> Bertl: where do you hail from?
13:29 < Bertl> Austria/Europe
13:30 < Bertl> (or do you mean my background?)
13:31 < dmj_nova> was curious which side of the pond you were on
13:31 < dmj_nova> I'm finishing up my degree at the University of Illinois though (so I live in Illinois, USA)
13:32 < dmj_nova> and have thus worked on things all night
13:33 < Bertl> my daily(nightly?) schedule usually depends on what I'm working on
13:33 < dmj_nova> novel writing, kickstarter planning, and designing parts for a moco rig will do that :P
13:33 < Bertl> i.e. I'm not really synced to local time
13:34 < dmj_nova> my sync changes, though I usually sleep at least partially during darkness
13:34 < Bertl> if somebody asks me, what timezone I'm in, I usually answer 'BUT'

12:27 < dmj_nova> morning Bertl s3bastian
12:57 < Bertl> here is how to boot the zedboard via jtag:
12:57 < Bertl> you want to get the ZedBoard_CTT_v14.3_121017.zip for some files
12:58 < Bertl> namely: ps7_init.tcl and stub.tcl
12:58 < Bertl> you also need the following from your design:
12:59 < Bertl> system.bit [PL bitstream]
12:59 < Bertl> u-boot.elf or some other elf binary [PS 2nd stage]
13:00 < Bertl> optionally (Linux Boot): zImage, ramdisk*.gz and devicetree.dtb
13:00 < Bertl> start xmd, then in the xmd prompt do:
13:00 < Bertl> connect arm hw
13:01 < Bertl> fpga -f system.bit
13:01 < Bertl> source ps7_init.tcl
13:01 < Bertl> ps7_init
13:01 < Bertl> init_user
13:01 < Bertl> source stub.tcl
13:01 < Bertl> target 64
13:01 < Bertl> dow u-boot.elf
13:02 < Bertl> con
13:03 < Bertl> this will connect to the target, upload the fpga bitstream (PL), initialize memory and MIO devices (ps7_init/init_user) and load the second level bootloader (PS)
13:06 < Bertl> the 'con' already starts the bootloader
13:06 < Bertl> if you like, you can also upload the linux kernel, initramfs and the devicetree like this:
13:06 < Bertl> dow -data zImage 0x8000
13:06 < Bertl> dow -data ramdisk8M.image.gz 0x800000
13:07 < Bertl> dow -data devicetree.dtb 0x1000000
13:07 < Bertl> and boot the kernel/linux with:
13:07 < Bertl> con 0x8000
13:07 < Bertl> note that it takes quite a while to transfer the kernel and initramfs
13:16 < s3bastian> good morning, just returned from the mensa for lunch ;)
13:17 < s3bastian> sounds great, can I add that to the wiki?
13:17 < Bertl> yeah, please, I have that on my todo list (the wiki) but please go ahead and put it there
13:19 < s3bastian> well I can take care of documentation when you focus on the zedboard ;)
13:19 < Bertl> deal! :)
13:19 < s3bastian> xmd is the normal serial terminal console to the zedboard right?
13:19 < Bertl> the debug/control environment via jtag
13:20 < Bertl> I currently refer to it as the jtag interface (it does a lot more, but that is the main purpose)
13:20 < Bertl> in contrast, the 'serial console' is the UART
13:21 < s3bastian> I see, its a tool from xilinx right?
13:22 < Bertl> yep, the zdeboard labels the connector (USB) as PROG
13:22 < Bertl> the serial console (via UART) is labeled (UART)
13:22 < s3bastian> do you have a URL at hand to acquire: http://zedboard_ctt_v14.3_121017.zip/
13:22 < s3bastian> do you have a URL at hand to acquire: zedboard_ctt_v14.3_121017.zip/
13:22 < Bertl> yep, sec, it can be downloaded from zedboard.org
13:22 < Bertl> http://www.zedboard.org/sites/default/files/design/ZedBoard_CTT_v14.3_121017.zip
13:24 < s3bastian> thnaks
13:24 < s3bastian> done: https://wiki.apertus.org/index.php?title=Axiom_Alpha#Booting_the_Zedboard_via_JTAG
13:24 < s3bastian> xmd is integrated in the Eclipse IDE directly?
13:24 < s3bastian> or how did you get it?
13:25 < Bertl> yes, it is part of ISE, you can start it from commandline (as I do) or via the GUI
13:25 < s3bastian> perfect, all added
13:25 < s3bastian> great progress i would say!
13:25 < s3bastian> well done
13:26 < s3bastian> I cant tell you how grateful for all the work I am actually :)
13:26 < Bertl> if you are at it, please also add the 'making jtag work' steps
13:26 < Bertl> as they are a prerequisite to using xmd
13:26 < s3bastian> will do
13:27 < s3bastian> that was in this channel yesterday right?
13:27 < Bertl> yep, if you need logs, just let me know
13:27 < s3bastian> yes please
13:28 < Bertl> http://pastebin.com/h1U8MUfa
13:51 < s3bastian> done
13:51 < s3bastian> https://wiki.apertus.org/index.php?title=Axiom_Alpha#Getting_JTAG_working_on_the_Zedboard
13:51 < s3bastian> There is one sentence: The libCseDigilent_2.4.3-x86_64.tar.gz contains two files in ISE14x/plugin which need to be copied to the ISE plugin directory:
13:51 < s3bastian> can you give me the names of the 2 files?, makes it a bit clearer I think
13:51 < s3bastian> even if there are just the 2 ;)
14:05 < Bertl> sure, sec
14:06 < Bertl> libCseDigilent.so  libCseDigilent.xml
14:24 < s3bastian> thanks, updated

14:23 < Bertl> good morning everyone!
14:46 < s3bastian> hello!
14:46 < s3bastian> sorry, about to leave for some shopping
14:46 < s3bastian> just replied to the axiom-dev mailing list discussion
14:47 < s3bastian> in that regard I would be very eager to know how the HDMI demo on the zedboard is implemented exactly
14:47 < s3bastian> If the Linux side serves images to the PL which feeds them to HDMI
14:47 < s3bastian> maybe you could reply to that thread as well?
14:48 < s3bastian> anyway, gotta go
14:48 < s3bastian> see you later

20:35 < dmj_nova> s3bastian: I just got a certain package in the mail!
20:36 < s3bastian> hurray!
20:38 < dmj_nova> Bertl: Is there anywhere you've documented the setup process?
20:40 < s3bastian> its in the wiki
20:40 < s3bastian> https://wiki.apertus.org/index.php?title=Axiom_Alpha
20:41 < s3bastian> The "Zedboard Development on Ubuntu 12.04 LTS with ISE 14.5 (Currently running in Virtual Box on a Mac)" part is from Gabe
20:41 < s3bastian> the rest below from Bertl
20:42 < s3bastian> maybe you can use the chance to correct Gabes approach, as he had trouble to get JTAG working
20:50 < Bertl> give me a few minutes ...
20:51  * dmj_nova will give it a try on 13.04
21:21 < Bertl> back now ... 
21:21 < Bertl> is Gabe here somewhere?
21:21 < dmj_nova> Bertl: s3bastian: So the DVD contains ISE 14.2...should I try to find a more up-to-date version somewhere?
21:21 < Bertl> I'm using the 14.5 ISE for most things, works fine so far
21:22 < Bertl> btw, I finished a setup for booting the zedboard via TFTP
21:22 < Bertl> which is a lot faster than the JTAG boot and doesn't have the drawbacks of SD card shuffling
21:23 < Bertl> http://vserver.13thfloor.at/Stuff/AXIOM/TFTP/
21:24 < Bertl> all you need to do is copy the boot.bin (as BOOT.BIN) to the SD card or to flash, connect the Zedboard via ethernet and have a dhcp/bootp and tftp server running somewhere on the network
21:24 < Bertl> the boot.bin will request an IP and server via bootp/dhcp and then start loading the advertised boot file, which should be an u-boot script
21:25 < Bertl> this is in turn executed, and can be used to customize the setup steps
21:25 < Bertl> an example script is provided to boot into the demo ZedBoard_OOB design
21:26 < dmj_nova> Also, what's this ISE Design vs Vivado thing?
21:27 < Bertl> for some reason, development environments nowadays have to have a fancy windows gui with many wizards where you do not know what you're doing :)
21:28 < Bertl> basically zynq design boils down to (AFAICT) creating a setup (i.e. what devices are enabled)
21:28 < s3bastian> nice, I will add that to the wiki page later
21:28 < Bertl> creating PL code (the FPGA bitstreams)
21:28 < s3bastian> cooking dinner atm
21:29 < Bertl> creating some kind of ARM code/environment to run on one or both of the arm cores
21:29 < Bertl> (that's the PS part)
21:29 < Bertl> in case of u-boot with Linux, the boot sequence is like this:
21:30 < Bertl> BootROM -> FSBL (in boot.bin) -> u-boot -> kernel, initramfs, PL-bits
21:31 < Bertl> but there is no need for all of this, i.e. you can get away with dummy PS code or bare metal apps as well
21:31 < Bertl> for example, the FSBL could already load everything
21:32 < Bertl> now as there are different approaches, there are different GUI tools to design a project
21:32 < Bertl> they all create a bunch of files and call a number of commandline tools to ultimately generate the config, PL bitstream and PS code

21:48 < Bertl> dmj_nova: do you have a preferred linux disto and/or linux setup/machine?
21:48 < dmj_nova> Bertl: My dev board is Ubuntu 13.04
21:48 < dmj_nova> *dev box
21:48 < Bertl> because IMHO the distro doesn't really matter for the ISE
21:49 < dmj_nova> That what Novacut needs atm
21:49 < Bertl> so I'd simply use that and install the latest packages
21:50 < Bertl> Xilinx_ISE_DS_Lin_14.5_P.58f_4.tar is what I used
21:51 < Bertl> and probably the simplest way is to install dhcpd and tftpd on that machine as well, so you can directly boot the code from there
21:52 < Bertl> (if you need any help with the setup and/or encounter any issues drop me a message here, I'll try to answer)
21:54 < dmj_nova> btw, this is somewhere on the xilinx site, yes?
21:55 < Bertl> yes
21:56 < Bertl> select zynq-7000 on the front page
21:56 < Bertl> select Developer Resources/ISE on the right
21:57 < Bertl> then pick ISE WebPack
21:57 < Bertl> then Download ISE WebPack Now
21:57 < Bertl> http://www.xilinx.com/support/download.html
21:58 < Bertl> you can select between vivado and ISE there and download a few models as well
21:58 < Bertl> as I see, they already released 14.6 :)
22:00 < Bertl> you also need to generate a WebPack license to actually use it
