Capture freezing on AI-Deck

[dielso]

Hello!

I've been trying to capture the camera images with the AI-Deck and I've been unsuccessful so far. I've based my code off the wifi-streamer and test_camera examples (mostly off the img streamer). When I call a capture (be it async or sync), the function halts infinitely, as if the camera never captures anything:

STAB: Ready to fly.
GAP8: Starting camera task...
GAP8: Buffers allocated and camera opened
GAP8: Starting async capture [...]

I don't think the problem is in the hardware, since the img streamer works ok.
My capture code is basically structed like this:

while(1){
  vTaskDelay(20);

  pi_camera_capture_async(&camera, buff, resolution, pi_task_callback(&task1, capture_done_cb, NULL));
  pi_camera_control(&camera, PI_CAMERA_CMD_START, 0);
  cpxPrintToConsole(LOG_TO_CRTP, "Starting async capture\n");
  xEventGroupWaitBits(evGroup, CAPTURE_DONE_BIT, pdTRUE, pdFALSE, (TickType_t)portMAX_DELAY);
  pi_camera_control(&camera, PI_CAMERA_CMD_STOP, 0);
  cpxPrintToConsole(LOG_TO_CRTP, "Finished async capture\n");
  [...]
}

Any help is very much welcome!

Hi! Since we don't have the full code here are some questions:

• So in anywhere of the code, do you enable the gap8 cluster?
• Do you send the picture via WiFi?
• If you take away all the other functionalities and have a bare minimum example, what is the problem then

Hello!
I'll answer topic-by-topic.

• Bare minimum example:
  I removed everything (or almost), except debugging stuff and the capture, and the problem is still the same. Strangely, it did capture one time but when I reflashed it, it didn't, so I'm assuming it was just a bug. I put the code on this repo.
• Enable the gap8 cluster:
  In my last code, I did enable it, but only after the capture for further processing. Why?
• Do you send the picture via WiFi?
  Nope!

Thanks for the answer!

Edit: I removed the camera rotation and it stopped stalling. Soon enough I'll come back to investigate this problem further.

The reason I asked about the cluster is because of this issue that you might be hitting: bitcraze/aideck-gap8-examples#100. That it works but CPX stalles

Interesting that the camera rotation had something to do with it... where in the code was this placed? Same as the wifi example I suppose?
