Hello ,

First of all，Thank you very much for your reply.

But I actually want to know how this offset is defined, including the offset in this header file(st-machine-storage-device-stm32mp.inc). Maybe I want to ask  , how does bootrom determine the address to load

TFA (tf-a-sdcard.stm32) from sdcard  into RAM. 

I tried to modify these address and burned successfully . this mp157 can still start normally.
