RK3399 Debug Serial port
Hi, What is the recommended voltage for RK3399 debug serial port? Can I use 3.3V or any 5V USB to UART bridge with this port or do I need to use 1.8V UART bridge with this port?By looking at the schematics and RK3399 datasheet it looks like 3.3V UART bridge is working with this board.
UPDATE: Tested CP2104 UART in 3.3V without any issues. dilshan replied at 2018-12-20 12:56

Can you please elaborate on how did you connect the cables?
Make sure you use correct baud rate 1500000
