Dear NXPs：
uSFE = false;
The Key attribute of MASTER_ECE_KEY is set to: Write Prot = 0; Boot Prot = 1; Debugger Prot = 1; KeyUsage = 1; Wild card = 1;
Then I want to call the bool eraseKeys(void) interface (csec_utils.h) to Clear all keys. But when
The bool getUID(uint8_t *uid) function returned a STATUS_SEC_KEY_NOT_AVAILABLE error when calling the CSEC_DRV_GetID interface. What should I do to erase all keys?
Dear lukaszadrapa:
Got it, thanks for the reply. Is there any way I can erase all keys?
Hi @Gideon
it makes sense. If you used: Boot Prot = 1; Debugger Prot = 1;
... then:
So, the secure boot must be successful and debugger can't be connected to be able to use the key.
Regards,
Lukas
