NMI HANDLER

[Recep]

Hi

with STM32H563ZI, (nucleo-h563) I work on freertos + tcp, when I try to make flash operation like erasing software goes NMI handler, but if not making erase just make flash_program it doesnt fail, because of I couldnt erase the sectorsi I cant program flash

this happens if I work in a rtos task, if I make without rtos it works fine,

Why this goes NMI handler in working task??
