D.3. Using LIBRSU Without a Valid SPT or CPB
LIBRSU can also be used when the SPTs or CPBs in flash are corrupted, but with reduced functionality. APIs are provided to restore a saved SPT or CPB, and also to create an empty CPB. After the CPBs ant SPTs are repaired using these APIs, the full LIBRSU functionality is available.
If only one SPT is corrupted, librsu_init API restores it from the good copy. If only one CPB is corrupted, the librsu_init API restores it from the good copy.
If both SPTs are corrupted, the librsu_init is still successful (return code 0) but some of the APIs return the error code ECORRUPTED_SPT when called. Both SPTs being corrupted cause LIBRSU to not be able to identify the location of the CPBs, and the CPBs are also considered as corrupted.
If both CPBs are corrupted, the librsu_init is still successful (return code 0) but some of the APIs return the error code ECORRUPTED_CPB when called.
