TDA3: UTILS: MDMA ERROR - invalid memory access in DSP!!! on TDA3x-RVP

Hi, roja c,

Your query has been forwarded to VSDK experts.

Hi Roja,

Are you making a similar allocation of non-cached shared memory from the DSP to IPU?

Thanks and Regards,

Piyali

Hello Piyali,

We are not making any allocation of non-cached memory.
We are porting an algorithm on standalone DSP which does not have any kind of non-cached memory allocations.

We have increased the DSP1_DATA_SIZE to 45 MB.

Hi Roja,

Thanks! To help me understand the exact changes to Vision SDK 2.10, kindly confirm if my understanding is correct:

You are using Vision SDK 2.10 and have made only one change of making the DSP1_DATA_SIZE = 45 MB.
The issue you are facing is only on DSP1 on TDA3x with this change.

Have you been able to debug further to identify the location in the code where you see this issue occur?

Piyali

Hello Piyali,

We had done few framework related changes
1. Integration of AR0135 Sensor.
2. Integrated the support to work with UYVY format of input video

We have resize function on the DSP which is done using Bilinear interpolation. There is 2 level nested for loop in the function. On exit of the for loop we start getting the MDMA error
