Accessing UART4 on RockPro64 (Armbian)

I have just found a solution. In case anyone is interested, here is the link: https://forum.armbian.com/topic/15419-ac...rockpro64/.
TLDR:
- In order to make the UART4 overlay load, I had to erase the SPI flash and boot directly from the eMMC because SPI1 and UART4 share the same pins
- If you are using the SoftwareSerial library on an Arduino or something similar, you need to use lower baud rates (e. g. 9600) to make the communication reliable
