Received my TinyPico boards I backed on Crowd Supply, and making some notes based on Seon’s Youtube video “MicroPython #1 – Lets Get Started”.
Download from: http://micropython.org/download#esp32
Using OSX, Terminal
ls /dev/tty.* /dev/tty.SLAB_USBtoUART
esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART erase_flash
esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 460800 write_flash -z 0x1000 esp32-20190731-v1.11-182-g7c15e50eb.bin
