Continue booting from specific NAND block on bf524

Hi,

I am working with the NAND boot procedure and firmware upgrade code of a bf524 based device.

What we need is a safe way to upgrade even if the power is lost during upgrade procedure.

The best way I can think of would be to put static init code in block 0 and the actual firmware starting from block 1 using Block Skip Mode for the boot procedure. That way we could put some basic recovery functionality in the init code to recover from broken firmware upgrade.

 

Question:

What would be the best way to re-direct the boot loader to a specific NAND-block from my init-code / startup program?

a. Set something inside the ADI_BOOT_NAND or ADI_BOOT_DATA structures?

b. Call bfrom_NandBoot() from the init code / startup program?

 

Anything special to think about?

Suggestions are appreciated!

 

thanks,

Jens
