TDA4VM: Error message from Mosaic node

Hi,

I am using SDK 7.2 and when frame rate is high in my application, I get the following message from time to time:

[MCU2_0] 955.131732 s: VX_ZONE_ERROR:[tivxKernelImgMosaicMscDrvGetReq:1002] Failed to Get Processed Request

The application runs fine otherwise.

Is it because of high display rate above 30 fps ?

regards,

Victor

Hi Victor,

Can you try a small change in the MSC driver? Can you increase value of macro VHWA_M2M_MSC_MAX_WAIT_LOOP_CNT to large value like 4096, in the file ti-processor-sdk-rtos-j721e-evm-07_03_00_07\pdk_jacinto_07_03_00_29\packages\ti\drv\vhwa\src\drv\vhwa_m2mMscPriv.h, then rebuild PDK & SDK and check again?

Essentially timeout value in scalar driver is smaller, which is not sufficient in usecase level.

Regards,

Brijesh

Actually the issue is still there after increasing VHWA_M2M_MSC_MAX_WAIT_LOOP_CNT.

Hi Victor,

What is the current value that you are using?

I had used earlier 4K for this macro, and after that i could not see this issue again.

I also tried 4K but didn't see the errors disappear. I disabled the printf for now so it is not a big issue.
