Hi.
settitng :
I am using MK64FN1M0VLL12 MCU , KDS 3.0.0, MQX V 1.1.1
Question :
I want to store some data into NVM or flash before Power down.
and right after Power on again , I want to read the data.and i added component successfully
and i found a useful post -> Re: Erasing Flash sectors in KL25 on the Freedom Board.
and i successfully write and read a data at first time. but it didn't work at second time
while debugging, i found that in UnhandledInterrupt, the process stoped.
can i get a answer about this problem? it's my code, and debugging window. i post the problem in MQX community because it may be problem in MQX interrupt
thank you very much
(someone told me that this was happening because the sector that i was trying to write to was not erased. the PE generated code does not erase the sector for me prior to writing to it, and i have to erase it myself but i don't know how can i erase the sector , should i edit MQX??)
