Cannot find /sys/class/fpga_manager/fpga0/firmware #11

Open agusmal opened 12 months ago

agusmal commented 12 months ago

Hello Pete Sorry I'm new to running an OS on this. I followed your steps on https://github.com/hdlguy/zcu104_ubuntu/tree/master/software/petalinux and I got stuck at the syntax step= echo top.bit.bin > /sys/class/fpga_manager/fpga0/firmware I can't find the /sys/class/fpga_manager/fpga0/firmware folder. I have turned on the ZCU board. Is there a step that I missed?

Hello,

It has been a while but I think you may need to create that folder. You would need to do that with sudo.

Actually,

That is a driver folder. If it is not there it means that maybe the fpga manager was not enabled in petalinux-config. It is also possible that Xilinx changed the way this works.

Good luck and let me know if you figure it out.

Hello

I started over using Vivado and Petalinux 2023.2 and recompiled the fpga and then followed my instructions in petalinux/readme.md. Everything worked, including the PL reconfiguration. Please note that you have to be root with "sudo su" for it to work.

Change to root with "sudo su". echo top.bit.bin > /sys/class/fpga_manager/fpga0/firmware

Sorry for the late response. Apparently, my SD card had an error, so I couldn't access the folder. When I replaced the SD card, I could find the folder.

Thank you for your kind response.

Great news. I'm glad it worked out for you. I still like to run a full OS on the ZynqMP while developing and testing. Later it is easy to shrink it down to an embedded Linux image.

Have a good 2024.
