Hello Community.


I am trying to read the kernel from the MMC card using command below:


mmc read 0x10800000 0x800 0x2000

mmc0 is current device


MMC read: dev # 0, block # 2048, count 8192 ... hangs

ON debug found data CRC error on read.

Write works perfectly OK.

I tried to read smaller chunks it reads randomly and hangs sometimes.

Could you please suggest possible problems.

With Regards,
