Hi,
Armbian_23.02.2_Orangepi5_jammy_legacy_5.10.110 works well with my OPI5. I can ssh to and play with it from my Debian desktop. I don't have HDMI monitor so I want to try serial port.
i'm using USB-TTL cable to connect OPI5 to my Debian box.
Then in Debian bash I use this command to connect to the port
screen /dev/ttyUSB0
Then power on the OPI5. The output is garbled:
If i change it to cs7 (screen /dev/ttyUSB0 cs7), the output is still something I cannot understand:
The stty command and output:
$ sudo stty --file=/dev/ttyUSB0 --all
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; discard = ^O; min = 1; time = 0;

I'm sure the USB-TTL cable lines are plugged as expected:
green line to RX, white line to TX, black line to GND. TX/RX/GND are as the offical PIN definition: http://www.orangepi.org/img/pi-5-pin-definition.png
Any idea what went wrong?
