Orange Pi Plus 2E - Turning off the Serial Monitor

[Peter Scargill]

I have been working with the legacy Ubuntu on this board with great success - and now on the latest nightly build of Ubuntu

 

ARMBIAN 5.32.170921 nightly Ubuntu 16.04.3 LTS 4.11.12-sun8i

 

All is well, thanks to this command added to /boot/armbianEnv.txt

 

overlays=uart1 uart2 uart3 i2c0 i2c1

 

I can now see all the ports - and both I2c channels - the ONLY issue I have is that  UART0 is occupied doing serial debug and for the life of me I cannot figure out how to turn this off. I do not need a serial debug port and would rather use this as a general purpose serial port. When I try however, debug info comes out..  Can someone tell me what I have to update to kill this?

 

Pete.

Did you already try to set 'console=display' in armbianEnv.txt (see bootscript for the difference please)

To disable all serial output u-boot recompilation is required, it's easier to use other UART ports and leave ttyS0 as is.
