Define "fault-signal" and "boot-error-flag". Thise may exist on your chip, but they don't on the overwhelming majority of systems. > reset-addr[31] = reset-addr_internal[31] | boot_error_flag; > So in case when you primary boot fails, and boot_error_flags is set, > next time when you boot, the address transforms into 0x1000_0000 This will only work on very specific hardware.
