TDA4VM: Minimal system setup

Hi Ugo,

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/vision_apps/docs/user_guide/index.html

Please follow vision_apps "build and run" section. This will allow you to do exchanges between C66 DSP and R5F.

Hello Keerthy, thanks for the answer.

We have already did that and we were able to run vision apps demos. The demos are very interesting and powerful. We are also creating an internal proof of concept starting from that codes and implementing what we want to show to the stakeholders.

Nevertheless, at the same time, the demos are very complex and they hide under to hood all the low level operations.

For this reason we are really missing a basic demos that shows us how to setup a minimum system on the target that do just the basics: boot, run some custom dummy code on the cores, exchance data between different processing unit and output some log using the serial interface.

Can you share a demo like that?

Hi Ugo,

The whole purpose is to get to IPC between different cores?

If yes there is ipc_echo_test firmware. Do you want to accomplish that at bootloader level? What you mean by basic demo?

Hi Keerthy,

I think the ipc_echo_test will be a good starting point. Thanks for mentioning it.

I found some information at the following link:

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/08_02_00_05/exports/docs/pdk_jacinto_08_02_00_21/docs/userguide/jacinto/modules/ipc.html

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/932825/faq-processor-sdk-dra8x-tda4x-how-to-use-ipc-example-application-echo-test-on-psdkqa7-0

They tells that we should be able to find it in the SDK RTOS (we are using 8.2.0.5) but I am not able to find it.

I can spot a folder called "pdk_jacinto_08_02_00_21" but it does not contain ipc_echo_test firmware.

Am I doing something wrong?

Best regards,

Ugo
