#1

Hi,

I am using Debian 16.09 for my dragon-board. I need 2 uarts for my application. Can I disable the boot messages from Uart 1(ttyMSM0) and use it for my application.


Dragonboard410c Debian #283 - disabling kernel messages to /dev/ttyMSM0 (/dev/console)

HI @bani_j,

For releasing ttyMSM0 from console, you can remove console=ttyMSM0,115200n8 line from kernel bootargs specified while creating the boot-db410c.img as mentioned in build instructions [1].

Thanks,
Mani
