TMS320LF2407A: How to verify the flash is programed correctly.

wang shu

I am working on an old design debug right now. Some boards stop working for CAN communication recently. I test all hardware until to the DSP input pins. So it may has some error during the program process. now i only has a .out file and use command "prg2xxw95 -p 240 –w 6 program\c2xx_bpX.out mycode.out" to program the flash. How could i verify the flash is programed correctly? Normally I use checksum to verify the program in the flash is correct. But i don't know how it work in this old DSP chip.

The flash programming algorithm verifies the status of each bit after programming. Although very rare, the value of some bits can change over time. How did you determine the issue is related to Flash and not something else?
