ATECC608B read cert failed and lock slot 0 failed

[wojiaoni]

Describe the bug After writing the signer certificate and device certificate, the read failed, but the buffer prepared for reading was still filled. However, there is inconsistency between the written and read certificates. The place where the authorization key identifier should be stored is where the user key identifier is stored when reading. Besides, the other bytes are exactly the same as the bytes written.

Another issue is that when I tried to lock slot0, the error code returned was 0xF4, but before that, I had successfully locked slot12

To Reproduce run the code printf("Writing Device Certificate\r\n"); if (ATCA_SUCCESS != (status = atcacert_write_cert(&g_cert_def_2_device, provisioning_device_cert, 408))) { printf("Failed to write device certificate: %d\r\n", status); goto exit; }

Expected behavior i want to return ATCA_SUCCESS and ATCACERT_E_SUCCESS
