Hi
I Use the Jetson TX1 Developer board with JetPack 4.6.2 and I want to disable the serial console on /dev/ttyS0.
I tried many ways to do this but in every way, I failed…
is there a way to disable this serial console on /dev/ttyS0?
I tried to modify the /boot/extlinux/extlinux.conf and remove console commands but I did not success.

Hi Hamzeh.nv,

Please share the full dmesg and also the device tree for further check.

Do you want to disable serial console log output from ttyS0?
May I know what’s your use case for this approach?

I want to add that serial console also exists in boot stages prior to Linux ever running. You have to distinguish between disabling serial console in Linux versus disabling this in boot stages; they are two completely different environments that just happen to normally use the same UART for the same purpose at the same settings (which makes serial console boot logs much more useful than dmesg).
