and also .mp3 is playing fine from NAND ,so there is no hardware issue.

i got Android home screen by booting from sd card.

 But once i play .mp3 files i got the error.

 Actually we downloaded android img file and flash it into NAND. then video and audio are playing fine.

 But once i prepared sd card by our source code and play the audio , i am getting the above error.

while comparing log of of nand and sdcard , i found fallowing difference.

By Nand
