ZynqBerry TE0726 - HDMI example boot problem
« on: February 03, 2018, 03:06:41 PM »
We tried to run ZynqBerry - Demo VIDEO/AUDIO Design with Video and Audio Example:

https://shop.trenz-electronic.de/en/TE0726-03M-ZynqBerry-Zynq-7010-in-Raspberry-Pi-form-factor?path=Trenz_Electronic/TE0726/Reference_Design/2016.2/te0726_m_demo3

After executing initial instructions:
  • Configure FPGA-Flash with Boot.bin
  • Copy image.ub, ffmpeg/mplayer Dateien, u-boot.rgba and Video or Audio Files on SD
  • Connect Monitor with HDMI
  • Reboot
we got a yellowish screen and the log from console looks like below:

reading image.ub
3605740 bytes read in 204 ms (16.9 MiB/s)
reading system.dtb
** Unable to read file system.dtb **
=>

Any ideas what is wrong?
The same behavior can be observed with other demos.

Hi,
did you use following files from the 2016.2 download:
  • Program Flash with: te0726_m_demo3\prebuilt\boot_images\te0726_m\u-boot\BOOT.bin
  • Add on SD:te0726_m_demo3\prebuilt\os\petalinux\te0726_m\image.ub       -> and other needed files for the demo.
I've try out this on my place, no problem:

Did you mix with programming files from other demos?
Which assembly variant did you use. Can you tell me complete product order name, please.
At the moment I think you did not use the correct files. Or did you generate this files by yourself and change the Linux configuration?

Thank you for your prompt respone.

Yes, we did use exactly the above mentioned files from the 2016.2 download

No, we didn't mixed the files from different demos.

It is TE0726-03M.

For now we only tried to restore and run a ready demo.

PS:
  • There is also newer Demo versions for Vivado 2017.1 (with  shop download page documentation) available

We tried several different versions (don't remember if exactly Vivado 2017.1) and the result was always the same.

It seems to lead to the same demo folders...

P.S.
Could the SD card capacity be a problem? We used a small 2GB card...

Which Vivado Version did you use to program QSPI Flash?
Can you send me the log file during flash programming process?

Did you try out Debian demo or other programming files before? Has your SD Card only one FAT32 partition, or more?

Yes this will be the new basic Reference Design overview page for 2017.2 design and newer.
Currently available 2017.4 Design is " Test Board", with Wiki description:

2017.1 Demo 1..3 are newer versions of 2016.2 Demo1..3.
2017.4 Test Board is only Linux Design with Board Part Files for 2017.4. See Wiki description.

Hi again,

Now we tried the demo for Vivado 2017.1 (with Vivado 2017.1 tool). This time we programmed flash with TCL commands, as suggested in https://wiki.trenz-electronic.de/display/PD/TE0726+Test+Board#TE0726TestBoard-QSPI

The TCL console looks like below:
Code: [Select]
TE::pr_program_flash_binfile -swapp u-boot

and the visual effects on the HDMI screen are the same as previously.



So far we used Vivado 2016.4 and programmed flash memory with Xilinx SDK => Program Flash. Programming process looked quite the same, it only finished earlier - there was no 'booting from configuration memory' part. Logs were like below:

Hi,

on 2017.1 only software reboot with scripts has not work, programming was successfull. Power ON/OFF restart system. IÄve fixed some of this problems on 2017.4 TE scripts.


For Vivado 2017.3 / 2017.4 , you must use a special FSBL on the programming setup. We have add this special FSBL to the 2017.4 "Test Board" reference design. See "Test board" wiki description.

Please do never mix versions of Xilinx tools.

Thanks for the remarks, they may be helpful for us in the future, but still they don't explain why the demo was not running.

We never did.

But... finally we discovered what was the problem. Some time ago we made 'Getting started with ZynqBerry' tutorial (https://eewiki.net/display/Motley/Getting+Started+with+the+ZynqBerry). There is a section concerning changes made in U-Boot, which contain command for saving the environment variables. These stored variables were the problem. It is described in this short discussion:
