Build From Source Fails Due to Mismatch of Micropython Version Relative to ESP-IDF Version

[genereese]

Hello. Thanks for your work on this driver and firmware version.

I'm attempting to include some additional support in the firmware image (like ESP NOW functionality) and I'm attempting to build via your source instructions.

However, it appears they may be outdated. Using the version of ESP-IDF specified in the instruction (v4.4.4), the latest version of micropython fails building - complaining that it requires version 5+ of ESP-IDF to build.

Updating ESP-IDF to version 5+ and attempting the build fails with the following error:

Including User C Module(s) from ../../../s3lcd/src/micropython.cmake
CMake Error at ~/esp/micropython/py/usermod.cmake:42 (include):
  include could not find requested file:

    ../../../s3lcd/src/micropython.cmake
Call Stack (most recent call first):
  esp32_common.cmake:22 (include)
  main_esp32/CMakeLists.txt:11 (include)

Did you have a specific version of micropython that we could checkout for this build process instead of checking out the latest version?

Alternatively, would you be able to update the instructions to work with the latest ESP-IDF version?

Either way, I appreciate your help.

As an update, I ran:

make USER_C_MODULES=../../../s3lcd/src/micropython.cmake

-with an absolute path, instead:

make USER_C_MODULES=/home/greese/esp32/s3lcd/src/micropython.cmake

-and I made further progress in the build but it still failed citing:

esptool.py definitely does not exist that that location with the v4.4.4 checkout of ESP-IDF - but it does exist there in the latest master checkout of ESP-IDF.

Ok, I had to do quite a bit to get this to work, but I was finally able to.

If you clone version v5.1.1 of ESP-IDF and use v1.21.0 of micropython, then modify uart.c under micropython/ports/esp32 to include:

#include "soc/uart_periph.h"

-THEN build using your instructions, everything seems to build OK.

Much appreciated.

MicroPython is using esp-idf 5.0.2. The BOARD names have changed, and there is a new BOARD_VARIANT as well. For the S3, if your BOARD has Octal PSRAM, add BOARD_VARIANT=SPIRAM_OCT.

cd micropython/ports/esp32
make submodules
make BOARD=ESP32_GENERIC_S3 USER_C_MODULES=/Volumes/MicroPython/s3lcd/src/micropython.cmake

Builds clean for me without modifications.

[genereese]

Yes, I wanted to try to get a build working with at least ESP-IDF v5.1.

Again, thanks for your work and I appreciate your reply, regardless.
