Hi,

I found the __mpu_init which does cache and MPU initialization, is called in the _c_int00, can it be called after entering main? Any consideration here?

Thanks.

Hello Andy,

Could you let me know what do you want to achieve by calling the __mpu_init in the main function?

Saswat,

Here i would like to know if it is must to call mpu init in c_int00, and the reason. In the AWR1843 demo mpu init is done in main function, i cannot understand the reason.

And my customer is using AWR2944 and doing the mpu init in main, is their any risk?

Hi Andy,

So in AWR2944 there is no risk of doing the MPU init in the int main.
So as there was a change to FREERTOS in the AWR2944 and the Gen1 devices like AWR1843 use the TiRTOS the structuring is different.
