Me No Dev 5502879a5b
v2.0.0 Add support for ESP32S2 and update ESP-IDF to 4.4 ()
This is very much still work in progress and much more will change before the final 2.0.0

Some APIs have changed. New libraries have been added. LittleFS included.

Name: SD_Update.ino
Created: 12.09.2017 15:07:17
Author: Frederik Merz <frederik.merz@novalight.de>
Purpose: Update firmware from SD card
Steps:
1. Flash this image to the ESP32 an run it
2. Copy update.bin to a SD-Card, you can basically
compile this or any other example
then copy and rename the app binary to the sd card root
3. Connect SD-Card as shown in SD example,
this can also be adapted for SPI
3. After successfull update and reboot, ESP32 shall start the new app
