SK-TDA4VM: Questions about TDA4vm memory？

maiunlei

Part Number: SK-TDA4VM

Hi experts,

My version is Processor SDK Linux for Edge AI 08.04.00. The memory of this board is 4G. But, when viewing memory using ' htop ', only 2G.

Why is this ?

So, When I run a large deep neural network model, procedure is killed directly.

Is this due to insufficient memory ?

Thank you

Looking forward to reply

The 4G memory is shared between different cores such as the C7x DSP, C66x DSP, etc. The 2G is what the ARM-A72 core running Linux is allocated with.

Hard to say with the current information. First recommendation is to see if you are able to run this model on the PC instead of the board. Steps for troubleshooting can be found here: https://github.com/TexasInstruments/edgeai-tidl-tools/blob/master/docs/tidl_osr_debug.md#steps-to-debug-error-scenarios-for-targetevmdevice-execution

Would you be able to follow this troubleshooting guide?

Takuma
