TDA4VH-Q1: Not enough size of MSMC

Hi Feng,

But why do you want to increase MSMC size? I think if i remember correctly, each C7x has at max 3MB of local MSMC, so its hw limit.

Hi Jadav,

Thanks a lot for your quick replay.

We want to generate the full trace dump of model inference in TIDLRT, which helps us to compare the inference result and the quantization accurrency.

We are now facing the input problems for the custom defined layers.

Hi Feng,

Sorry, but how is this related to MSMC size limitation? Can you please elaborate?

Hi Brijesh,

I paste the screenshot below.

When we open the trace dump. I got a “ Not enough memory to allocate intMemPtr in MSMC"" error. And the process stuck

Hi Feng,

But if it is trying to allocate more than supported max memory, it is not going to work. It will then try to allocate scratch memory from DDR..

Hi Brijesh,

If I am not misunderstanding your reponse. You means that "Not enough memory to allocate intMemPtr in MSMC" is just a message which shows that the app will allocate more memory from DDR. So it is no need to increase the MAX available memory of MSMC manually. The reason of the stuck could be another problem which need to analyse our TIDL application?
