taking better look at drawing here [1] my device is actually NanoPC-T6LTS
on the right hand side there is USB-C(Debug-UART) label. So this what
I'm using for console. I connect using USB A-to-C. According to dmesg
the device reports itself as:
uchcom0 at uhub4 port 1 configuration 1 interface 0 "QinHeng Electronics USB
Serial" rev 1.10/2.64 addr 4
uchcom0: CH341
ucom0 at uchcom0: usb0.2.00001.0
Trying to increasing the speed I'm seeing this error:
lifty# cu -l usb0.2.00001.0 -s 1500000
cu: tcsetattr: Invalid argument
I'm using USB A-to-C cable (~20cm long) plugged to USB-A port directly in
my T-14. Not sure if it is cable or driver. I will try to dig more details
later today. May be will try my luck with USB C-to-C
thanks and
regards
