TDA4VM: Target ID is invalid, jumping into DSP1

Hafiz Muhammad Owais

Part Number: TDA4VM

Hi TI,

I have previously tested my custom kernel on the DSP1. Now, I am trying to change the target to A72 and have done several additions to make it work, here are those steps:

1. Added the TIVX_TARGET_A72_0 where the node is called

2. Added the TIVX_CPU_ID_A72_0 where the custom kernel is defined, same as done with the DSP1

3. Added A72 in the conceto.mak for the compilation.

Now the problems are:

Firstly, self_cpu which is actually assigned by tivxGetSelfCpuId(); is only getting the DSP1, where is this API get the CPU ID from and how to change it for A72?

Secondly, I am receiving the error which is : Target ID is invalid which is for obvious reasons that my declared target where I called the node doesn't recognize A72_0. How to deal with these errors and add A72_0 in it.

With best regards,

Hi Owais,

This essentially means that this kernel/node is not registered with A72. Could you please check in your host implementation that kernel is registered for A72?

Hi Brijesh,

I have added the A72 in the host kernel along with the other two targets (DSP1 and DSP2) and also added the A72 condition in app_init.c for registering and unregistering of kernel which were previously running under C66. The kernel registration seems to be ok now as it isn't generating "Target ID invalid error". However, a new error arose:

ion_buffer_destroy: buffer still mapped in the kernel and Bus error , it seems the error is due to ION memory ?

Besides, I checked that tivxGetSelfCpuId(); which is still giving DSP rather than A72.

Hi Owais,

Please open new thread for the new questions and close this thread if your question is answered.

Regarding your question, it seems the buffers are not cleaned up during exit. Please make to Release all objects from your application.

Hi Brijesh,

Thank you for your response.

How to release all objects? I am currently transferring the firmware files j7-*-fw to sd card for every kernel update and the relevant application binary. I am not sure if there is any other files needs to updated as well.

Hi Owais,

I mean in the application, call vxRelease for all the objects that are allocated.

Hi Brijesh,

In my log, there is no such warning related to object release due to which I think all objects are properly released.

ok, then maybe some deinit is not being called. Which application are you running?

It looks like application mapped these buffers, but did not free it up. In Linux, anyway, when process exits, all resources are freed up..

I am running vx_app_tidl_avp.out with my trained network and added custom kernel which was previously working well on DSPs.

Hi Owais,

I think there is some deinit is not called. Or may some other object memory is not released.

I think this error is not catastrophic. You could ignore for the time being..

Hi Brijesh,

The application stops with core dumped and Bus error. I have tried to detach the drivers from remoteproc but nothing helps.

Hi Owais,

Usually we use one thread for one question. So i think your target id question is answered and it is working. Even application is exiting.

Can you please close this thread and start a new for core dump issue?
