VL805 and µPD720201 not working on Pi 5

I'm testing vl805 and µPD720201 on pi5 and the usb adapter card doesn't work.

VL805

The pci card can be enumerated, but the usb device cannot be found and takes a very long time to boot up.

µPD720201

µPD720201 directly fails to boot the system, causing kernel errors

Hi @tltangliang

Had the exact same issue on the exact same hardware (I believe, PCIe x1 Slot for RPI 5 from 52PI, but the PCB is black, and exact same looking USB3 card with VL805 on it).

I ended up with the VL805 card working, by adding this line into /boot/firmware/config.txt:

	dtoverlay=pcie-32bit-dma-pi5

I tried a lot of different PCIe options (both by dtoverlay, dtparam, and cmdline.txt) but this one is the only / single one that made it work (others options aren't needed). Works fine, around 400 MiB/s without warnings from dmesg.

From /boot/firmware/overlays/README the only options I didn't try is pciex1-compat-pi5, on which l1ss, no-l0s and no-mip sub-parameters are available (but I still don't know what they do). I also have to get information about CLKREQ# things.

It looks like having PCIe devices working with the Pi 5 isn't as plug and play as expected (at least as I expected...), but everything seems to turn around these options.

Hope this may help!

That's awesome! Upon seeing your message, I immediately tested it, and adding this configuration made it work. But the system cannot boot from USB through VL805. However, the µPD720201 still cannot be used.

Thank you very much!!!
