Hello together,

i would like to setup my custom board, to boot from eMMC.

In uBoot I found the fuse command.

What bank/word I have to write to access the boot_cfg[1/2/4]?

In ref manual 35.3.2 Fuse Shadow Memory Footprint I see 3 times boot_cfg at addr 0x05 to 0x07.

Does that mean bank 0 word 5/6/7 for boot_cfg[1/2/4]?

If yes, are bit 0 to 7 from boot_cfg[1] are found at bank 0 word 5 bit 0 to 7?

Greetings, Hans

@ Victor & Yuri,

thanks for your reply. I found the glue between u-boot fuse command (with banks and words), the addresses in chapter 5-1 and the position in the OTP-Area.
