MPC5644C Data Flash erase and watch dog

Discussion created by Qifeng Chen on Apr 21, 2016



I'm using data flash FEE for key parameter stored.

Power down strategy and some other application, will update the FEE.

I tested erase one block data flash will take nearly 1s, this is extremely beyond internal watchdog and external watchdog in my design. This is will cause Flash ECC error while access this area.


So I want to know how I can clear the watchdog while erase the Flash (from NXP Flash Lib), or if any other solution to fix this issue.
