TDA4VM: TDA4VM

Part Number: TDA4VM


Currently, we are working on a TDA4VM board for the A72 core processor. We want to take the CPU performance status for the same. We are using the below-mentioned APIs for the same.

appPerfStatsCpuLoadPrintAll();

appPerfStatsCpuStatsPrintAll();

 

But the application completely hangs after this print and it does not respond after that. Please see the below-mentioned print it provides before hanging. 

Summary of CPU load, ====================

CPU: mpu1_0: TOTAL LOAD =   0. 0 % ( HWI =   0. 0 %, SWI =   0. 0 % )

Also, we tried the same with the sample application for the single CAM. But the same issue persists. Please find the running procedure below:

./vision_app_init.sh

./run_app_single_cam.sh

After running the application, we enter the testtool P. Then we got the same issue as mentioned above.

Please let us know if we are doing anything wrong or any other procedure to view the CPU load status.

Thanks & Regards

    Hi Sambeet Kumar,

    Any changes in the released SDK? Because single camera example is working fine on EVM and could get the performance stats also using above APIs. 

    Most likely the hang is coming because one of the core is not responding.. Can you please connect to all cores using CCS and see if they are still alive?

    Regards,
