TDA4VM: create new vision app for jacinto 7 using CCS

Part Number: TDA4VM

Hi

I have seen the vision demos and DL demos that are installed with the PSDK_RTOS like app_tidl and I am apple to run them. I want to create a new app similar to the demos, and I am not sure where should I start.

I tried to change on the app_tidl project and use the VGG16 model instead of tidl_io_mobilenet_v1_1 which is used in the demo by changing only the tidl_network_file_path and tidl_config_file_path parameters in the config file. Then I built the project and loaded it to Jacinto using the SD card. But when I run it, it keeps waiting after printing:

app_tidl: Verifying graph ...

I thought that it is okay to change the model since both models have the same input and output. Is it possible to solve this problem?

Also, what is the correct way to create my own app, should I start from scratch or can I use the demos and modify them?
And if I want to create it from scratch how can I do it?

Regards
Ayman
