Thor fuse burn

[zax]

Hi,

I’m preparing to apply secure boot on our custom board

There’s not yet start

But I’ve seen there’re some people meet some issue

such like Thor with most fuses burned except `SecurityMode`, giving errors - #7 by JerryChang

I’m confusing about “fskp_fuseburn.py tool does NOT support fuse enabled board.
the purpose of this FSKP tool is to burn keys in a factory setting, it currently does not capable of burning a board after PKC/PKCSBK and ODM Key Valid bit in BootSecurityInfo have been set.” by JerryChung’s response

Is that mean I can’t fuse second times if I’ve fuse the “PublicKeyHash”, “PscSecureBootKey”, “OespSecureBootKey” ,“SbSecureBootKey” and “BootSecurityInfo” bit 9 in the first time even if the “SecurityMode” has not been fussed?

hello zax,

@zax

Is that mean I can’t fuse second times

that’s correct, you should burning all the fuses you need in a single operation.
