Hi All

If for some reason your USB tty donlge dont like 1500000bps reduce your tty bps to 115200 and output on another serial output port

  1. Connect via SSH to your Rock Pi S (username rock, password: rock)

rock@ipaddress

  1. Edit hw_intfc.conf and extlinux.conf

sudo su
mkdir /tmp/efi
mount /dev/mmcblk0p4 /tmp/efi

nano /tmp/efi/hw_intfc.conf

Make this change

intfc:uart0=on

save and exit

Make this change

nano /tmp/efi/extlinux/extlinux.conf

append earlyprintk console=ttyS0,115200n8

save and exit

Refer to connection of GPIO for your version of board
