Linux/AM3715: Nand boot and redundancy

Guru 20755 points

Part Number: AM3715

Tool/software: Linux

Hello,

I am trying to understand which blocks in nand should be used for nand boot.

Is it that the first 2 blocks are used for redundancy, so that if one it not ok, the other is checked ?

I've tried to understand from TRM how it is treated but could not find description for this SPL redundancy.

Can you please describe it ?

According to my testing it seems that block 0 and block 1, each can be used for SPL boot, but I don't understand what is actually being searched in each block before trying the next block.

Thank you,

Ran
