Dear TI,
We run c7x vision apps basic demo like this (J784S$ EVM board, with PSDK Linux+RTOS v10):
root@j784s4-evm:/opt/vision_apps# /opt/vision_apps/vx_app_c7x_kernel.out --cfg app_c7x.cfg
Below is log:

We can see regular printfs from main, but not from c7x.
Specifically nothing is printed from
ti-processor-sdk-rtos-j784s4-evm-10_00_00_05/vision_apps/apps/basic_demos/app_bringup/c7x/app_c7x_target_kernel_img_add.cpp
Even if printf is added to app_c7x_target_kernel_img_add_create it does not appear anywhere.
How can we see these prints?
Background is basically: we would like to create similar app but with kernel on th R5F MAIN core, and we found this basic demo as most similar in order to start. Do you maybe have an example of simple vision app that executes kernel on R5 and prints output?
Best regards,
Milena
