OTPMK seemed already burned as shown below:
=> md 0x020cc014 1
We've already burned SRK fuses and get the HAB working in open mode. However, after executing the following to close the config to enable secure boot, device is not booting anymore.
=> fuse prog 0 6 0x02
Programming bank 0 word 0x00000006 to 0x00000002...
What could be the issue, please help! Thanks.
