Hi,

Can you first try to run the FEE example provided in HALCoGen? They are available in Help->Examples.

If the example is working correctly on the device, you should debug/verify the settings done by RTOS.

I think the problem is that I am calling the TI_Fee_WriteSync routine when not in privileged mode. I am running FreeRTOS. I've seen examples of using the SVC interrupt to do privilege mode stuff, and it seems cumbersome. Is there a method I can use to implement persistent memory variables without having to go into privileged mode?

Hi,

Writing to FEE bank is only possible in privilege mode.

What is the best way to enter Privileged mode? Does this action have to be done via the SVC? Is there a simple way to declare a routine that operates in Privileged mode?
