ESP-NN

Did you replace the NN folder in the lib as we do for XIAO esp32? and for the AI Thinker ESP32-CAM, you don't need to do that.

now, try to delete the library and re-add a new one and compile.

jacob_jipson

@salmanfaris The problem was resolved. Thankyou so much.

salmanfaris

@jacob_jipson Glad to hear that.

Error compiling for board AI Thinker ESP32-CAM.

@mahesh02 From the current Arduino ESP32 board files, we don't need to install the ESP-NN separately.

But try to choose the esp32 board version 3.1.3 and check, as I also faced issues with the latest esp32 board file.

Need Help: Error compiling for board AI Thinker ESP32-CAM.
