AWR2944: Where to find the realization code of the MPU CACHE operation in freertos

Hi,

For CACHE MPU related operation, i found the header files in mcu_plus_sdk_am273x_08_02_00_26\source\kernel\dpl, source code files in mcu_plus_sdk_am273x_08_02_00_26\source\kernel\nortos\dpl for nortos, but not find the source code files for freertos. I cannot understand how to do the operation in freertos, would u pls help guide me?

Thanks.

Andy
