Forum Post: RE: No prints from kernel running on DRA608(AM335x) board

Hi All,

With SDK 7.0, linux - 3.12, custom board, I used early_print() to get prints. No prints from printk(), Also kernel hangs

after calling do_initcall_level() twice. Sequence: start_kernel -> rest_init() -> kernel_init() -> kernel_init_freeable() -> do_basic_setup() -> do_initcalls  -> do_initcall_level()

The same image gives prints(printk()) on EVM.

1. I checked bootargs using early_print(), it's correct:  console=ttyO0,115200n8 root=/dev/ram0 rw ramdisk_size=65536 initrd=0x81000000,64M rootfstype=ext2

2. I checked my uart0 pin mux in dts file, it matches that in uboot.

3. I also tried removing uart0 pin mux in dts as it'll be initiallized in uboot, but the issue remains the same.

What am I missing?

Regards,

Gangadhar
