We're trying to implement secure boot through HAB here. We have signed the SPL/U-boot image through cst and burnt the fuses corresponding to the public key. Now when testing for HAB events with the u-boot command 'hab_status' it displays the following:
Secure boot disabled
HAB Configuration: 0xf0, HAB State: 0x66
Missing in the output is the print 'No HAB Events Found!', but no HAB events are obviously displayed either.
Further debugging shows that the u-boot function 'hab_rvt_report_status()' returns HAB_WARNING (0x69).
So question is, what does this error/warning indicate, what might be wrong with our setup?
