Original question:

[TDA4M] I was wondering If I could see the run time of each layer in a TIDL node.

[TDA4] Dump activations from TIDL node

Hi,

We are facing some mismatch in executing a custom NN in host emulation and on target. Actually, in host emulation, the output is perfectly fine, whereas on target our net outputs data resembling random input.

We have analyzed that the input layer is identical in both cases, so we need to debug the net execution itself.

1) Is there any obvious reason (like in TIDL conversion) that can cause this behavior?

2) Is there a way to dump the layer activations from the C7 while executing a demo app using Linux and tiovx? Or do we have to connect via CCS and load the binaries etc. manually?

Regards

Dom

    Hi Dom,

    My suggestion would be to first run the model standalone with TIDL.

    For debug steps please refer to TIDL user guide: psdk_rtos_auto_j7_06_01_00_15/tidl_j7_01_00_00_00/ti_dl/docs/user_guide_html/md_tidl_fsg_steps_to_debug_mismatch.html

    For steps to run using CCS you can refer to: psdk_rtos_auto_j7_06_01_00_15/tidl_j7_01_00_00_00/ti_dl/docs/user_guide_html/md_tidl_sample_test.html

    Hi,

    I haven't heard back from you, I'm assuming you were able to resolve your issue.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
