Peter Scargill Posted September 21, 2017 Share Posted September 21, 2017 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.

tkaiser Posted September 21, 2017 Share Posted September 21, 2017 Did you already try to set 'console=display' in armbianEnv.txt (see bootscript for the difference please) Link to comment Share on other sites More sharing options...
zador.blood.stained Posted September 21, 2017 Share Posted September 21, 2017 To disable all serial output u-boot recompilation is required, it's easier to use other UART ports and leave ttyS0 as is. 1 Link to comment Share on other sites More sharing options...
