just radxa official debian supports it.amrbian and yours does not support.

[Joshua-Riek]

I don't see any errors in dmesg, but I do know the interface works.

However, I'm working on a major Bluetooth and WiFi firmware update. This may fix the issue. But if it does not, I dont think there is much I can do.

[BaconSoong]

The problem is still. please check the dmesg.txt.[ dmesg.txt ](url) i find [ 8.770177] rk-pcie fe170000.pcie: PCIe Link Fail [ 8.770370] rk-pcie fe170000.pcie: failed to initialize host,as picture shown. and lspci does not show the bluetooth&wifi device. but, the offical os works ok, Could it be caused by the device tree?

[Joshua-Riek]

Make sure your PCIe card is fully plugged in, I know it works.

[BaconSoong]

i'm sure my PCIe card is fully plugged in, because i change the official ubuntu firmware, the bluetooth&wifi works and lspci does not show it, but it exactly works.

[Joshua-Riek]

I don't know what to say, it works perfectly on both the Rock 5B boards I have.
