Dear All.
The addresses of fusemap are 0x400, ...., 0x450, 0x460, 0x470, 0x6D0, etc.
And, only part of 0x450 is accessable by H/W BOOT_CFG pins.
How to access 0x430[21:20] from software or bootloader?
"md" command of u-boot is usable?
I want to read current setting of 0x430[21:20], TAMPER_PIN_DISABLE.
And, I want to change 0x430[21:20]. How can I change it?

Have you found the solution?
Hi mannsikchung,
You can use the fuse API in u-boot for reading and writing:
=> fuse read <bank> <word> [<cnt>]
=> fuse prog [-y] <bank> <word> <hexval>
You can find more details about it and a example in the following link: Burning eFuses on i.MX6 and i.MX7 - i.MXDev Blog
Thanks,
Breno Lima
What exactly i.MX series processor do you mean? Please specify it first.
Best Regards,
Artur
As the title says, I'm using i.MX6ULL.
