Azure RTOS FILEX LEVELx using on chip flash

I am looking for any example project that uses Azure RTOS FileX and LevelX using onchip flash.

I understand the programming flash can be segmented and used for general purpose file storage but I cannot find any example across any series packages which uses the on chip flash. Is this even possible?

I am mostly looking on how to set the levelx configuration parameters in STM32CubeMX. I know how to integerate the low level flash drivers from the HAL.

Hello @dvescovi 

Please refer to the example below to set the LevelX in your application. The example demonstrates how to create a Fat File system on the NOR flash using FileX alongside LevelX.

this example does NOT use the on chip flash. It is using an external flash interfaced by spi.
