But on BananaPi R3 MINI just this and no error:

Same package version of firmware (linux-firmware-20231211)

Same linux 6.6.10 (also 6.7-rc4)

Edit:

Wrong UART?

Do you use ftdi or cp2104 uart? cp2102 and others have this strange behaviour

It is a ch341-uart (idVendor=1a86, idProduct=7523, bcdDevice= 2.64)

I guess I must have changed it at some point, I had wifi working…

Anyway, I ordered some ft232 so I’ll change it…
