Hi All,
I purchased a 4.3" LCD board with an esp32s3 chip for the purpose of playing with micropython and having a board that had a variety of input and output options. I’ve struggled for the last couple of weeks trying to get an lv_micropython build.
I can build micropython (@master), I’ve built the esp-idf display demos and deployed those to the board, so I have confidence in my build environment and the hardware.
I’ve tried building lv_micropython on OSX and Linux, I’ve tried building the release/v8 build with the 4.4 esp-idf and the top of tree (@master) build with esp-idf 5.1.2. I’ve had no luck at all. I know that I probably need @kdschlosser 's lv_bindings build for the RGB panel driver, but even just trying to build the esp32 port without anything exotic fails for me. Below I’ve documented the processes I’ve tried (at least the most basic variation of them) and the failures they’ve generated.
My primary goal is to play with micropython on the board, and of course be able to output things to the display, not necessarily become an master in lvgl and lv_micropython… I guess what I’m saying is that if someone could build a firmware binary for me… I’d take it 
Any help would be greatly appreciated.
Regards.
Lance

## Start from scratch
% rm -rf esp .espressif
% mkdir esp
% cd esp
## Get v4.4 of esp-idf (lv_micropython and esp32s3 supported)
% git clone -b v4.4 --recursive https://github.com/espressif/esp-idf.git
% cd esp-idf
% git submodule update --init --recursive
% ./install.sh all
% . ./export.sh
## Clone lv_micropython (use release/v8 branch hoping for stability)
% cd .. (to ~/esp)
% git clone -b release/v8 https://github.com/lvgl/lv_micropython.git
# I know I need an RGB LCD driver, which isn't in this release, but just
# trying to get something to compile.
