Re-routing UART console on AM5728 SDK

chandan kumar

Hi,

We would like to re-route the debug console to a different pin set on same UART. As of now, by default, UART3 of ball D27 (MUX_MODE2)and C28 (MUX_MODE1) are configured as console pins. I would like to re route the same on to UART3 but with DIFFERENT ball configuration as AB3(MUX_MODE4) and AA4(MUX_MODE4). How do i achieve this? I have tried to modify the offset of UART3 in <SDK>/u-boot/arch/arm/include/asm/arch/mux_dra7xx.h but to no change! The console logs are still on the same UART.

Regards,
Chandan

Hi,

This modification will be effective only in U-boot. The same must be done in the kernel device tree.

Hi,

Yes. We have made the changes in device tree to reflect the changes in kernel. But still the console messages doesn't seem to re route

Thanks,

Hello Srinidhi,

Did you change the console parameter in kernel cmd line?

Best regards,
