SK-TDA4VM: TIDLRT shared memory allocation error

Julien Berthiaud

Part Number: SK-TDA4VM

Hi,

When running a model with onnx_main.cpp app in edgeai-tidl-tools with argument --dev_mem 1, we face the following error:

MEM: ERROR: Alloc failed with status = 25 !!!
Could not allocate memory for a Tensor of size 3136

The issue seems to happens when this TIDL function is called:

ptr = TIDLRT_allocSharedMem(64, size);
- How can use shared memory without getting this error ?
- What is the cause of this error ?
- Where can we have access to TIDL library source code in order to see what is happening inside ?
Thanks

Hello,

How much total memory are you allocating for your application?

Also, have you been able to run the sample applications successfully, or do those fail as well?

Regards,

Lucas

We ran the models from TI model zoo successfully. The error happens when we run a small MNIST model we tried to convert our selves with the importer tool. The input size is only 28x28 images. How can we see how much memory is allocated ? The error seems to state that we are only trying to allocate 3136 bytes for input (28x28x4).

Can you please make the input dimension of the original model as 4 dims instead of 3 - Like 1x1x28x828

BTW, is this model working without shared mem- That is --dev_mem 0
