The Datasheet states that the plfash sectors can handle at least 1000 P/E cycles for the 1mb and 2mb flash block variants.
Aside from the fact that this seems horrendously low, how is this meant to work in practice?
Does this mean you can only update the firmware 1000 times in the field?
What is the failure mode after the 1000 cycles?
How can i detect if it is failing?
Do i need to track my number of p/e cycles to prevent exceeding it?
I don't expect to update 1000 times in the field, but I certainly will update firmware more than 1000 times during development and also for automated test setups.
