Any error from the CSU while in the boot process is recorded in the PMU_GLOBAL.CSU_BR_ERR register. This register also determines the boot success or failure. On failure or error condition, the 16-bit error code is recorded in the CSU_BR_ERR register.
A configuration BootROM error code is 8 bits long. This means that with an allocation of 16 bits, two error codes are stored. Error bits [15-8] correspond to the first image error code and error bits [7-0] indicate the most recent image error code (Table: BootROM Error Bits).
Table: BootROM Error Bits describes the configuration BootROM(CBR) error codes.
Table: BootROM Error Codes describes the configuration bootRAM (CBR) error codes.
