TDA4VM: How to use the logging API

Christophe ALLART

Part Number: TDA4VM

Hello

I want to use the logging API on the C7 coprocessor.

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/tiovx/docs/user_guide/group__group__vx__debug.html#gaa169ff47c2d8cb7dd9ec4a0d32f12510

and

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

Which seems related (produce similar outputs).

The question is : can we use VX_PRINT() API on coprocessors and can we dynamically change the level (debug zone VX_ZONE_ERROR VX_ZONE_INIT ... ) of a running app on Coprocessor ?

Thank you for your help

Hi,

If you are using OpenVX, essentially vision apps, firmware on the C7x, then yes, we can use VX_PRINT API to print the logs from the processor.

Typically we dont change the log level at run time. We would set it once during initialization and use it for the code execution.. So although it is not tested, but i see no reason why it can't be changed dynamically.

Hi,

The use case would be to change the log level on a coprocessor ( C7 or C66 ) without having to recompile/rebuild the firmware, which may be a long process, or even without having to reboot the target.

I will test that.

Thank you

hi,

Unfortunately, OpenVX log level change requires rebuilding source code, copying it to SD card and rebooting the board..
