I'm trying to get the Debug Authentication provisioning to work. I managed to write it from within the application, but then I found the errata sheet(es0565-stm32h562xx563xx573xx-device-errata-stmicroelectronics.pdf) which states otherwise:
"Chapter 2.2.35: Debug Authentication provisioning cannot be done from the application when TZEN is disabled"
I tried to do the provisioning with RSSLib->DataProvisioning(), as mentioned in the errata sheet, but I end up getting a hardfault.
I'm using the nucleo-h536zi-board, trustzone is disabled.
RSSLIB_DataProvisioningConf_t a;
a.pSource = sData;
a.pDestination = (uint32_t *) (0x0FFD0100);
a.Size = 0x60;
a.DoEncryption = 0xCACA0AA0U;
a.Crc = 0;
uint32_t c = RSSLIB_PFUNC->NSC.DataProvisioning(&a);
Since the CRC is not correct, I expect to get the CRC error instead of a hard fault.
Is there something I need to set up before calling DataProvisioning? I tried to find an example, is there one somewhere?
Best regards,
Peter
