FreeRTOS running crashed at when operate embedded flah

[PYF.1]

Hello everyone,

I create my firmware project in FreeRTOS environment at STM32L476 EVB, I place code in bank1 and when I execute bank 2 flash section operating like erase/program , firmware will crashed, but if without FreeRTOS condition, the same operate condition could running well. Are there any limitation for embedded dual bank operating if under FreeRTOS environment ?
