TDA4VM: How to leave the trap function

Hello Zhihua,

To understand your question more, which SDK is this on (e.g. PROCESSOR-SDK-RTOS-J721E version 08.01.00.13,PROCESSOR-SDK-LINUX-J721E version 08.01.00.07, etc) ? 

Also, by MPU violation, is this on the R5 or the A72 core?

Regards,

Takuma

Hi Takuma,

We are now using PROCESSOR-SDK-RTOS-J721E version 08.00.00.12(and last number 04, 08). It's on the R5 core.

Thank you!

Best Regards,

Hi Zhihua,

Can you please provide a little more details on what is the use case here. What are you planning to do once you exit the trap function? Will the application try to recover from the error state or is it gonna exit?

Hi Parth

The use case is that I don't want the SW stuck in the trap function when MPU violation occurs because the violation is blocked by the MPU protection and it doesn't affect anything actually.  Just got informed is enough. Maybe after several times of MPU violation, I will perform other recation but not only once. 

Thank you!

Hi Zhihua,

Apologies for long delay in response.
Can you please share a sample code which we can try on our end that leads to MPU violation and get stuck in a trap function?
