Hello,
  I would like to use UART on ROCKPro64 for bi-directional communication with Arduino Pro Mini.
According to documentation, UART4 TX, RX are connected to Pi-2 connector pins 19 and 21.
But there is no relevant device file - /dev/ttyS4. I can see only /dev/ttyS0 and /dev/ttyS2. I do not want to use these two, because they are already intended for Bluetooth and console.
How could I enable /dev/ttyS4 in my Linux system?
I am using rockpro64-debian-desktop-mrfixit-191226. ‘uname -a’ shows:
Linux Debian-Desktop 4.4.207 #1 SMP Fri Dec 27 11:35:59 EST 2019 aarch64 GNU/Linux  
Thanks in advance!
