Face Detection example runs but not Face Recognition (AIV-591)

Hello,

I can't get the face recognition example to work on my board. After the flash stages I get the following output:

WARNING: Given section not found in any memory region. Check whether the LD file is compatible with the definitions in get_mem_regions in idf_size.py WARNING: Given section not found in any memory region. Check whether the LD file is compatible with the definitions in get_mem_regions in idf_size.py WARNING: Given section not found in any memory region.

And then the monitor stage gets stuck at the last line in the following:

The monitor will output "...APP CPU up" after "call_start_cpu1" line for the face detection example. The face recognition example never outputs that and is struck on "...cpu_start.c:142" line.

Initially, I thought it was the issue with "WARNING: Given section not found in any memory region." from ESP-IDF size. However, I tried commenting out most of the main_app.c in face recognition example to the point where that warning doesn't show up anymore. However, monitor state still gets stuck on "...cpu_start.c" line.

Any ideas or suggestions on how to fix both issues: memory region warning and app not starting correctly (stuck on cup_start.c:142 line)? Thank you in advance.

Hi, are you using branch idfv5.0?

[danielyang2000]

Yes, I tried both the master branch and idfv5.0 branch.

[Auroragan]

Hi, for master branch, need to use idf release/v4.4, For idfv5.0 branch, could you try on idf branch: release/v5.0? It works fine for me on this branch.

[danielyang2000]

Thank you for the help. I still don't know what's causing this issue but I was able to run the face recognition code in the face-detection example folder. It must've been the configuration or something else set up in the face-recognition example folder that's breaking the code.

@Auroragan For the master branch in esp-who, I am using the release/v4.4 and it is able to detect face, nose, and eyes as expected using the esp-who framework, but when I switch to idfv5.0 branch in the esp-who and switch to release/v5.0 then it fails to detect face, nose and eyes using the webUI.
