Tool/software: Linux
Hi,
I am using TI Sitara PSP having Linux version v4.4.41. I am porting Linux on my custom board. I ported linux v3.2 successfully on it bur due to unavailability of some required drivers I have decided to use linux v4.4.41.
in that I modified uboot for custom board, It loads a linux kernel. currently I am facing one issue I am booting from sd card but linux kernel hangs at
"Waiting for root device /dev/mmcblk0p2...". I also searched on e2e community regarding a same problem but it could'nt solved a problem.
So Please guide me where I am wrong,
following is my kernel log
