Now I installed the FFS patch on MQX4.0.2 on TWRK60F120M.
And I installed the wear leveling without installing MFS on NAND FLASH.
When I try to use read/write NAND FLASH in a interrupt, it prints: "assertion failed: 0, file simple_mutex.cpp, line 141".
After digging into it, I found it can not lock the mutex because it can lock the mutex in a interrupt.
Do anyone have any ideas how can use read/write based on FFS in a interrupt?
