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,

Prashant
