Good day!

I am new here and just a new comer.

It is sucesssful to make firmware for ESP32, but when I am making a new firmware for my ESP32-CMA, I met the following 2 issues:
.. ....
[1094/1336] Generating ../../genhdr/qstrdefs.collected.h

freeze error executing "/boards/manifest.py": Error in manifest file: /boards/manifest.py: [Errno 2] No such file or directory: '/boards/manifest.py'

ninja: build stopped: subcommand failed.
ninja failed with exit code 1
... ...
Q1：Is it due to the latest version of micropython, not the required one( MicroPython v1.18-63-feeeb5ea3-dirty ）for CAM？
Q2：Is location issue of /boards/manifest.py? Which manifest.py shall be care about?

If anyone met the same or similar issues like me, plese help ad many thanks in advance!
Have a nice day!
George

you should replace
set(MICROPY_FROZEN_MANIFEST ${MICROPY_PORT_DIR}/boards/manifest.py)
to
set(MICROPY_FROZEN_MANIFEST ${MICROPY_BOARD_DIR}/manifest.py)
in ./boards/ESP32_CAM/mpconfigboard.cmake

also you should create folder ./boards/ESP32_CAM/modules
and comment
#define MICROPY_PY_BLUETOOTH (0)
at ./boards/ESP32_CAM/mpconfigboard.h

at ./micropython/ports/esp32 folder run:

1. idf.py set-target esp32
2. idf.py -DUSER_C_MODULES=../../../../micropython-camera-driver/src/micropython.cmake -DMICROPY_BOARD=ESP32_CAM build
3. cd ./build;esptool.py --chip esp32 merge_bin -o flash_image.bin @flash_args;cd ..
4. esptool.py --chip auto --port /dev/ttyS0 --baud 921600 write_flash -z 0x0000 ./build/flash_image.bin

in case of ERROR: Call to MP_REGISTER_MODULE(camera, mp_module_camera_system, (1)
replace
MP_REGISTER_MODULE(MP_QSTR_camera, mp_module_camera_system, MODULE_CAMERA_ENABLED);
to
MP_REGISTER_MODULE(MP_QSTR_camera, mp_module_camera_system);
at ./src/modcamera.c
