AM3352: Disabling debug console in U-boot

Part Number: AM3352

Hi Team,

A TI AM335x processor is running with uboot v2017.01 and kernel v4.9.59 and required to redirect uboot and kernel boot up and debug logs to a file then debug console "/dev/ttyO0".

We required to disable debug console for the u-boot to stop uboot debug prints and for that we have added "status = disabled"  in the &uart0 node of the am335x-evm.dts file but still console is working normally.

Please share your inputs to disable debug port for the uboot.

Thanks and regards,

Harsh

    For U-Boot disabling the console is not as simple as that, as there are many dependencies in the code on a working console. I had already provided a tested solution in an earlier thread, have you tried following those steps exactly (there were also two patches attached I created just for this)?
