J721S2XSOMXEVM: [J721S2XSOMXEVM] TIDL concat layer Issue

Part Number: J721S2XSOMXEVM

Tool/software:

Hello, TI member,

We are currently verifying our network model using TIDL RT.

We got expected results in host emulation mode, but the results are different in target mode with same environment.

This problem occurred while using the current PSDK 9.0 version, and in PSDK 8.6, both the host emulation mode and target mode results were the same.

 As a result of comparing each layer dump, the different results started from the concat layer.

Input 0 : TIDL_CustomLayer
Input 1 : TIDL_DataConvertLayer

Output : TIDL_ConcatLayer

I hope I can get help with this issue.

Best Regards,

  • Hello,

    I do apologize for the late response. Is this still a blocking issue for you?

    From my understanding, with SDK 8.6 you are not seeing issues (host emulation or target). However on 9.0 SDK, you are seeing the correct output with host emulation, but differing output when running on target. 

    If so, are you able to test this with 9.2 SDK and see what the results are?

    Can you also provide the compilation log and inference logs when running on 9.0 SDK with debugTraceLevel =2 ?

    Best,

    Asha
