Hi,

I'm wondering if anybody has a mechanism to trigger a self-reset after an IAP mass-erase (erase all user sectors) ?
I'm thinking of using the watchdog since code execution is not possible after mass-erase (? unless there is a trick not involving ram code execution). The spec is a little unclear regarding the mass-erase time so I'm not sure which timing I should set the watchdog to.
Spec notes max 20ms, but does not clearly state if the 20ms is for the whole operation, or 20ms max per sector.

If anybody has a suggestion it would be appreciated.

Thks in advance,
Sylvain
