I'm using imx6ul。I want to read fuse value using uboot.

fuse read <bank> <word>

what is bank?  what is word?

[turmary]

The Reference Manual could tell us what bank, what word map to fuse address.

Chatper On-Chip OTP Controller (OCOTP_CTRL) :

bank0,word1 map to Address 0x21B_C410 (0x410).

read fuse you can use tools in uboot named imxotp,

imxotp read <index>

- read fuse at 'index'
