Dear Chander Kashyap,

Curious to know, what the 0x02020030 hardcoding number means here? It is a pointer to a API or hardware register, or anything else, how this simple function perform the data transfer from mmc to ram?
0x02020030 is iROM address, which contains pointer to API (copy from mmc
from DDR) in iROM.
Well, as you can see yourself here, an external reviewer has no chance to reand and understand this code. As mentioned before, this needs serious rework.
Best regards,
