Introduction

cd .. (the micropython folder of tflite-micro-micropython)

Changed:

- git apply ../boards/esp32/MICROLITE_SPIRAM_CAM/micropython.patch
  MicroPython allocates the full SPIRAM installed on the esp32-cam module for its heap. However, the esp32-camera driver needs some SPIRAM for its image buffer. The patch modifies main.c in micropython/ports/esp32 such that part of the SPIRAM is kept free for the camera driver.

- git apply ../boards/esp32/MICROLITE_SPIRAM_CAM/micropython.patch !!! This is not needed any longer and the patch does not work anymore !!!
