Hi,

I have custom dm8148 board, I have configured all the pinmuxes in uboot, so i have commented out all the pinmuxing from the kernel. but when I boot kernel I dont get any message after "Starting kernel ...", I have enabled CONFIG_DEBUG_LL that also doesnt help. How should I proceed ?

I have tried all possible combinations of ttyo0 in bootargs aswel.

Thanks & Regards

Mike

    Have you tried with ttyO0 (not ttyo0)?
