Dear "Gupta, Pekon",
In message 20980858CB6D3A4BAE95CA194937D5E73EA186A6@DBDE04.ent.ti.com you wrote:
you can tweak your hardware to split it, and many micro-controllers do it (especially for safety critical applications). Example: Suppose 'default' entry-point (or reset entry-point) = 0x0000_0000, Now OR your MSB bit with the fault-signal or boot-error-flag.
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.
Best regards,
