shivm28Hi everyone, I am currently working on Ubuntu 16.04 but I feel switching to Ubuntu 14.04 will be better for development. There are some issues with drivers while working with Xilinx ISE as well. Any suggestions?19:38
CarlFKshivm28: I would stay with 16.0419:53
CarlFKshivm28: describe the problems you are having, someone may be able to help you out19:54
shivm28CarlFK: I am trying to install drivers for ISE but getting this error:
tpbTitle: Ubuntu Pastebin (at
shivm28I searched a lot about the possible solutions and I figured out that the script is unable to find kernel version. This is because there is no support for the current kernel.19:58
CarlFKchecking linux kernel version... hello.c:1:30: fatal error: linux/utsrelease.h: No such file or directory20:01
CarlFKthat looks worth looking into20:01
tumbleweeddo you even need those drivers?20:06
shivm28tumbleweed: to connect board with computer and to program using ISE20:06
tumbleweedwhich board?20:07
shivm28Atlys board20:07
tumbleweedwe can program that with hdmi2usb-mode-switch (well, openocd20:08
CarlFKI was wondering bout that20:08
shivm28I am not able to flash firmware on my board for some reason.20:09
tumbleweedif you're using the toolchain that hdmi2usb-litex-firmware gives you, you don't need any ISE drivers (you'll never use ISE GUI either)20:09
tumbleweedwhat's the "some reason"?20:09
CarlFKtumbleweed: is vizzini-dkms needed to program, or just to connect to the hdmi2usb serial console?20:09
shivm28Do I need Xilinx cable to program the board?20:10
CarlFKAtlys board - first time, needs jumpers moved20:10
tumbleweedcorrect. for programming you need ixo-usb-jtag, fxload, openocd20:10
tumbleweedshivm28: no20:10
shivm28tumbleweed: I will share the error in a minute.20:11
shivm28I have removed the jumper JP11 to program the board. Is that correct?20:13
tumbleweed says you only need the jumper for permanent flashing20:15
tpbTitle: Digilent Atlys Board: Jumpers and Video Connections · timvideos/HDMI2USB Wiki · GitHub (at
tumbleweedwhich probably isn't what you're going to be doing for development20:15
tumbleweedso, yes20:16
shivm28I am stuck at this point from past 5 minutes: Is that normal?20:27
tpbTitle: Ubuntu Pastebin (at
tumbleweedrun with -v to see what's going on20:30
tumbleweed5 mins is a little long, yes20:30
tumbleweedbut a couple of minutes is normal20:30
CarlFKtumbleweed: line 3 has the -v20:31
shivm28tumbleweed: still stuck at same point20:31
tumbleweedoh, right, didn't see it was wrapped20:31
CarlFKshivm28: [email protected]:~$ openocd -v20:32
CarlFKOpen On-Chip Debugger 0.9.0+git20151228 (2016-01-26-04:52)20:32
tumbleweedshivm28 has a newer one, should be good20:33
shivm28Should I run openocd using that command in a new terminal?20:33
CarlFKI would, to make sure you have the right version20:34
tumbleweedCarlFK: I assume shivm28 is using the openocd from conda20:34
tumbleweedit looks like it from the paths20:34
tumbleweedthat'll be fine20:34
tumbleweedso it just hangs at line 41 forever?20:35
tumbleweedand you never see the DNA being printed20:36
tumbleweedthat usually happens almost instantly20:36
CarlFKyeah, I was wondering  about that20:36
shivm28Nothing except what I shared20:36
tumbleweedpower cycle the atlys and try again?20:37
shivm28removing JP11 pin, right?20:38
tpbTitle: Ubuntu Pastebin (at
shivm28Now, I can see DNA being printed but getting unknown flash device error.20:41
tumbleweedno, you're flashing so you'll need jp1120:41
shivm28same error20:42
tumbleweeddid you power-cycle with jp11 connected?20:43
tpbTitle: Detect "Error: Unknown flash device (ID 0x00ffffff)" on Digilent Atlys · Issue #24 · timvideos/HDMI2USB-mode-switch · GitHub (at
tumbleweedfrom the description of that ticket, the issue is jp1120:45
shivm28tumbleweed: I tried doing everything with that pin.20:46
CarlFKhere is mithros steps:
tumbleweedwell, clearly not the one right thing :)20:47
tumbleweedeasy answer is don't bother with flashing for now, load-gateware is a lot faster20:48
tpbTitle: Ubuntu Pastebin (at
shivm28load-gateware seems to work but I need to load firmware as well, right?20:55
shivm28Again stuck at this point:
tpbTitle: Ubuntu Pastebin (at
shivm28Should I try with another board or try building the image file again?21:00
tumbleweednow you press the reset button on the board21:01
shivm28still stuck :(21:03
tumbleweedbasically at that point it should boot and load the firmware via flterm21:03
CarlFKalso press enter at flterm21:03
tumbleweedoh, is that it21:04
shivm28no response to enter key21:05
CarlFKI also remember un/pluging the usb cables21:06
shivm28When exactly? While loading the firmware?21:06
CarlFKno - after it is loaded21:06
CarlFKand I am wondering if the jumper needs to be put back21:06
tumbleweedCarlFK: according that faq normal operation is no jumper. It's only needed the once21:07
CarlFKok, removed then ;)  fiddled with21:07
shivm28make gateware-load is executing successfully but make firmware-load is not working.21:08
CarlFKshivm28: try this:21:10
CarlFKwget hdmi2usb-mode-switch -v --load-fx2-firmware hdmi2usb.hex21:10
CarlFKthat has worked for me at least once, then I put it on this page:
tpbTitle: Flashing Firmware · timvideos/HDMI2USB Wiki · GitHub (at
tpbTitle: Ubuntu Pastebin (at
shivm28CarlFK: How can I check if it worked or not?21:16
CarlFKshivm28: flterm --port  /dev/ttyVIZ021:17
tpbTitle: Ubuntu Pastebin (at
shivm28After pressing enter, I got BIOS>21:18
CarlFKi think that is progress21:18
CarlFKtype help21:18
shivm28Available commands:21:19
shivm28mr         - read address space21:19
shivm28mw         - write address space21:19
shivm28mc         - copy address space21:19
shivm28crc        - compute CRC32 of a part of the address space21:19
shivm28ident      - display identifier21:19
shivm28serialboot - boot via SFL21:19
shivm28flashboot  - boot from flash21:19
shivm28memtest    - run a memory test21:19
CarlFKplease dont paste more than 2 or 3 lines here21:20
shivm28Oh sorry21:20
CarlFKtry ident , memtest and flashboot21:20
CarlFKyou should be getting H2U 00:52:47> - I think you get the BIOS prompt when it fails to boot, like fails a memtest.21:20
shivm28I tried flashboot but got error : Invalid flash boot image length 0xffffffff21:21
CarlFKI am guessing it didn't get loaded21:22
tpbTitle: Ubuntu Pastebin (at
tumbleweedthat's the bootloader21:24
tumbleweedthat's the point where you do load-firmware, and type "serialboot" into the console21:24
shivm28serialboot is returning TIMEOUT21:26
tumbleweedfrom load-firmware?21:26
shivm28I am following this link right now:  wget hdmi2usb-mode-switch -v --load-fx2-firmware hdmi2usb.hex21:27
tumbleweedok, I'll stay out of that21:27
shivm28Trying to flash prebuilt firmware.21:27
tumbleweedCarlFK: that's fx2 firmware, not the problem you need to be dealing with21:27
shivm28I will try building the image file again maybe21:28
shivm28But I believe it has to do something with that jumper pin :(21:29
tumbleweedno, it doesn't21:29
tumbleweedserialboot works when flterm is run with the kernel argument pointing to a firmware file21:30
tumbleweedthat's what make firmware-load does21:30
tpbTitle: Ubuntu Pastebin (at
shivm28Some progress I guess21:32
shivm28using make firmware-load and then serialboot21:33
CarlFKI would download  and use prebuilt to confirm that bit works go up a few lines from that wiki page21:34
shivm28But now I am stuck at this point.
tpbTitle: Ubuntu Pastebin (at
shivm28waiting for gdb21:34
