USB port does not work with current rootfs #33

Closed tomtrafford closed 1 year ago

tomtrafford commented 1 year ago

I've noticed that updating the rootfs from 2.0.2 to the most recent version (3.0a3) causes the USB port to stop working. I have changed the version between 3.0a3 and 2.0.2 a few times and I found that the USB port always works on 2.0.2 and never works on 3.0a3.

It's not a trivial issue, the driver refuse to probe the driver after this commit, my guess is that Vivado needs to be updated to create a device tree providing the attribute "usb-phy". Given this is not a critical issue, I suggest we wait for the project update to 2022 or 2023

Who's working on the update to a later vivado? We need to get V3 out the door in June, and the USB needs to be working by then...

Glenn already has some change regarding the Vivado update and will test it soon, if it doesn't work, there are ugly workarounds I could do (but I would prefer to avoid that)

Glenn has a solution to this problem and it actually goes to the FPGA repo, it should be ready before the release in June

This is fixed in the PandABlocks-FPGA repo: https://github.com/PandABlocks/PandABlocks-FPGA/pull/114
