Dear TI expert,
I am using TDA4VM in a custom board which main purpose is to capture frames from various cams. I use vision_apps single and multi cam demos to capture csi but I have some bash codes that take of ser-des link creation and imager configuration using linux i2c-tools. The process I use for camera streaming is the following:
1.- Run bash codes to initialize
2.- Run run_app_single.cam.sh in interactive mode and select my imager
3.- See the live frames through eDP or save the raw/yuv files
4.- Stop the application by sending 'x' from the main menu
5.- If I want to recapture, I re-run from step 2 (without the initialization) and it works just fine
The problem is that, even after I exit cam capture application successfully, if I somehow reset the deserializer (either with RESET_CTL register or by reinitializing the cam with my bash codes), and re-run run_app_single_cam.sh the code gets frozen. After some troubleshooting, we figured out the application gets stuck at app_run_task_delete() function.
Questions:
- Is there any process that waits for csi signals even after the application gets de-initialized?
- When the application gets frozen, on the display, we see last captured frame from previous time we ran the code. Can you think of a reason for this to happen?
- Could you please help with some insights on how to debug this?
We are using ti-processor-sdk-rtos-j721e-evm-07_03_00_07.
Thank you very much in advance!
Luis
