    Hi,

    changing the CONFIG_SYS_NS16550_COM1 in uboot I get boot logs of uboot on uart1. But I don’t get any messages

    after starting kernel, What changes do I need to do in the kernel ?

    I also tried setting console = ttyO1 but doesnt help ?

    Thanks & Regards,

    Mike

    Mike,

    Can you provide full boot log (console output) (u-boot + kernel)?

    Are you aligned with the below wiki page?
