Custom board image building for HTG-ZRF16

[Armanhbabaei]

Hi everyone,
I’m trying to get PYNQ running on the Hitech Global HTG-ZRF16 board. I understood that this board is not currently supported by PYNQ so I have to build the SD card image for it myself. I’m following PYNQ/sdbuild at master · Xilinx/PYNQ · GitHub to do this. I’m working with ubuntu 18.04 , vivado 2020.1 and petalinux 2020.1. Because I could not find BSP for HTG-ZRF16,I’m using the bsp for ZCU216 according to this link: AMD Customer Community
I get an error using the make command which terminates the make process. the error is “zlib1g:i386 package can not be found” but I have installed that package already and I have tried so many things to fix this but none of them worked.
How should I fix this? I would appreciate any insights regarding this matter.

Hi,

I just had this same exact issue (same vivado and petalinux version even).

1. If you got Petalinux working on your board, then you can easily generate a BSP from there with the petalinux-package bspcommand. Using a BSP for a different board is not suggested since they depend heavily on the configuration your actual board (different device tree and peripherals even).

2. For the zlib1g:i386 issue I did as follows:
   sudo dpkg --add-architecture i386

sudo apt update

sudo apt install zlib1g:i386

3. I posted a similar question last week and got an answer from the PYNQ team. Please check it since it might be helpful in your case:

Adding PYNQ to an existing Petalinux build on a new board without BSP

Hi @crispy245 You will need to use the BSP for the AXU15EGB board. Either use the one supplied by Alinx, or make your own one using Petalinux (you will need to look through the Petalinux documentation on instructions on how to do this). If Alinx don’t supply a BSP, I would contact them directly to ask for one. Making your own BSP can be difficult, especially if you don’t have any experience with device trees. To make your PYNQ board folder, you should follow the file structure of the other PY…

Hello @crispy245 ,

Thanks a lot for sharing these steps. I followed your suggestions and used the same commands but unfortunately, I’m still running into the same issue. It seems that the package is installed but the check_env can not detect it.

Also I would appreciate it if you could give me any references for generating the bsp. Thanks.

Hi @Armanhbabaei ,

1. Please check at what point the check_env.sh script is failing. For instance in my case it would constantly fail trying to check for gcc-multilib since that is not a binary by itself (or at least on my distro) so I deleted from the check_env.sh script. Like this I had many other errors but I just went step by step checking where would the script fail.

2. Have you ran setup_host.sh? It will install the version of the tools needed to build the PYNQ image.

Both check_env.sh and setup_host.sh can be found in PYNQ/sdbuild/scripts.

3. In regard to the petalinux issue, do you have petalinux already installed on your system? Have you gotten an image to work already? I wrote a small guide on how to get a Petalinux image to work. Make sure to create a working Petalinux image, test it and then generate a BSP from it (i’ll explain that later).

PetaLinux install: - HackMD

4. Once the Petalinux image is created and you know it’s working accordingly, then go ahead and create the BSP by running the following command:

petalinux-package bsp from the directory where you created the original petalinux image.

Please don’t hesitate to ask any other question.

Best,

Aldo
