Which memory is within the specified CMAC authentication memory ? Where can get this information?
Hi W Z,
The "specified CMAC authentication memory" is determined by which address range is passed to the CPU1BROM_calculateCMAC function. This function can either be called by the boot ROM when using one of the secure flash boot modes, or can be called by the application code. The following app note provides details on how to use the CMAC keys for Secure Boot:
