I am working on a bootloader for TMS570LC4357. I need to check of the application has been programmed or if the Flash address is erased.
1. The erased state of Flash is a known value. If I read it, will this produce a correctable error or uncorrectable error or is it for some reason unpredictable?
2. If my NMI service determines that this error should be ignored, can I return from interrupt or is the offending return address not stored on the stack like other interrupts?
