I need to use both UART0 and UART1 for communication with an MCU.
However, UART1 is attached to the Linux system console
I already disabled the login commenting the line:
ExecStart=-/sbin/agetty --noclear %I $TERM --keep-baud 115200,38400,9600
which disables root autologin via sytem console (root login is enabled by default).
However, I would like to disable all messages which are forwarded to
/dev/ttyMSM0 by default, including boot messages and kernel messages.
Following the instructions given here and here , removing the
from the kernel command line, doesn’t do trick.
After flashing the boot image with
fastboot, kernel messages are shown as always, boot messages also.
What it the correct way to completely disable the kernel messages logs to
I could accept boot logging, but after that I would like to have the
/dev/ttyMSM0 free of kernel messages and login (I actually only accomplished to disable login/autologin).
Thank you in advance for your help.
