hello,

 

I recently see the imx28 the reference manual, but I had a problem.As follows,

 

ocram:   0x0000 0000   ~    0x0002 0000

ocrom:   0xFFFE 0000   ~ 0XFFFF FFFF

 

I do not understand how he is working during power-up, the cpu pointer is pointing where , OCROM or OCRAM.

In addition, Where the boot image data loaded?

 

 

I learned that the ocrom  inside has a loader code, so  the code  is already written into the chip Manufacturers???
