Android UART output options

Products Support DragonBoard410c
#1

Hi.
(I am a beginner in English.)

I disable all console output (shell, debug, printk)
I want to use it generally.
It is output as ttyHSL0 and must communicate with external device via this port.

Please let me know what options I can set.

Hi ,
We generally do two things to disable the debug UART.

  1. remove the flag “CONFIG_SERIAL_MSM_HSL_CONSOLE”.
  2. remove the dtsi configuration So we can use the same GPIO for other purpose.

Thanks,
