=== Run "burn_key" command ===
Sensitive data will be hidden (see --show-sensitive-info)
Burn keys to blocks:
 - BLOCK2 -> [?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ??]
        Reversing the byte order
        Disabling read to key block
        Disabling write to key block

Burn keys in efuse blocks.
The key block will be read and write protected


Check all blocks for burn...
idx, BLOCK_NAME,          Conclusion
[00] BLOCK0               is not empty
        (written ): 0x00000004f0100000000002320000a2000005c4dee2658fb407f00000
        (to write): 0x00000000000000000000000000000000000000000000000000020100
        (coding scheme = NONE)
[02] BLOCK2               is empty, will burn the new value
.
This is an irreversible operation!
Type 'BURN' (all capitals) to continue.
BURN
BURN BLOCK2  - OK (write block == read block)
BURN BLOCK0  - OK (all write block bits are set)
