How to work NAND boot if 2nd page of FW1 is Bad.

Hello,

 

I read an errata ERR008506 and understand about FW2 load condition.

 

Our NAND have 2KB page size.

In this time if first page of FW1 is bad, it will start to load FW2 by this errata.

 

If 2nd page of FW1 is bad, ROM read 4KB (frist and 2nd page of FW1)

and ECC checking fails because 2nd page is bad.

 

In this condition, how to work ROM bootloader after this error?

 1) start to load FW2?

 2) load 3rd page of FW1?

 3) others

 

Best regards,

Ishii.
