F28M35H52C1 Restart issue after flash memory update

Other Parts Discussed in Thread: UNIFLASH

Dear Supporter,

Currently, we are using the F021 Flash API on the F28M35H52C1 device(C2000 side, with ECC).

The C2000 does not start after C2000 Flash memory update.(Reset method : M3 Watchdog)

But we use external power on/off; in this case C2000 is running.

We already verify the flash memory contents using the Uniflash.  And we checked XRS signal(Low) when M3 watchdog expired.

Question:

How can restart both C2000 and M3 after Flash memory update?

    Please check the device TRM boot ROM chapter, the control subsystem boot ROM does not automatically start the application in flash. An M3 application has to send a boot mode IPC command to C-boot ROM to make it start the application in its flash.

    hope this helps.

    Best Regards
