relationships between flash operation and interrupt

[gumu]

Hi NXP team,

If write/erase the flash different block, do I need to disable all interrupt?

if yes, how to fix FS26 watchdog feed problem, Since I have to fresh watchdog in duration which is based on GPT, the interrupt of GPT is disable by operation of flash。

Thanks for any advice！

Hi @gumu,

There is the “Read-While-Write” (RWW) that allows performing a read and a write simultaneously (applies only when operations are in different blocks).

When it comes to interrupts, it depends on where the vector table, the ISR and the resources that the ISR reads are stored.

For example, if you want to reprogram Block_0, none of the above mentioned can be stored in that block.

Daniel
