Based on loboris fork of micropython
sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial
git clone --depth 1 https://github.com/loboris/MicroPython_ESP32_psRAM_LoBo cd MicroPython_ESP32_psRAM_LoBo cd MicroPython_BUILD ./BUILD.sh menuconfig ./BUILD.sh ./BUILD.sh flash # reboot board disconnecting power
- download micropython from http://micropython.org/download#esp32
If you are putting MicroPython on for the first time then you should first erase the entire flash
esptool.py --port /dev/ttyUSB0 erase_flash
esp8266
download micropython from http://micropython.org/download#esp8266
wget http://micropython.org/resources/firmware/esp8266-20180511-v1.9.4.bin
erase (optional ?) and upload
