I'm debugging a boot loader that verifies and runs one of multiple images in a failsafe mode, for this I need to determine if a reset was caused by the watchdog, an app call, or a HW reset.

According to the UM LPC_RGU->RESET_EXT_STAT0 should return the reset cause, however when I enter the code I find this is always zero.

Is this being cleared by the boot rom code, and if so where is it storing the status?.

Has anybody found this yet?.
