when we use imxRT1176 MCU.When both cores are used, M7 is used as the main core, M4 is used as the slave core, and M4 uses flexspi to erase and write to the norflash. At this time, do we need to close all interrupts on both cores.
Hi @xiaozezitian,
I believe this is a duplicated post from the following: https://community.nxp.com/t5/i-MX-Processors/imxRT1176-if-flash-is-to-be-erased-all-interrupts-of-bo...
If it is ok with you, I will provide follow-up on the linked community post in order to prevent double efforts.

If flexspi is initialized in the M7 core and then deinit flexspi ,Not using the flexspi interface in M7 anymore。
Then start the M4 core, flexspi is reinitialized in the M4 core,Use the flexspi interface to operate FLASH in M4.
Is it possible to use like this.
