I tried to used ESP-CAM to firmware TinyML model from Edge Impulse. I ran successfully example from Edge Impulse but cannot ran my model created by Edge Impulse.
Err:
Error compiling for board AI Thinker ESP32-CAM.
The picture of the tiny text is hard to read. Click on the "Copy error messages" button (see top right of your image) and paste the text into a reply.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
It looks like your build is including two copies of "objs.a" which contains the functions:
DebugLog(char const*)
ei_read_timer_ms()
ei_read_timer_us()
ei_putchar(char)
One is in:
libraries/
fire_detection_inferencing/
src/
edge-impulse-sdk/
porting/
espressif
and the other in:
libraries/
fire_detection_inferencing/
src/
edge-impulse-sdk/
porting/
arduino
I don't know why your build is using the same file from both directories. Perhaps deleting one of the two directories will work around the problem.

Thank you so much. I tried it and it ran successfully now. Idk why the lib form edge impulse concludes both files. btw it still run
