MicroPython on M5Stamp-C3

No idea why the ESP32-C3 needed to be written starting at 0x0, rather than 0x1000, but sure enough it did. I couldn't figure out why nothing could seem to be written successfully to my STAMP-C3, but basically nothing was working. Now, thanks to a blog post I found, it's successfully running the generic ESP32-C3 MicroPython binary.
Successful esptool.py commands:
Result on REPL:
Build:Feb 7 2021
rst:0x1 (POWERON),boot:0xc (SPI_FAST_FLASH_BOOT)
mode:DIO, clock div:1
MicroPython v1.17 on 2021-09-02; ESP32C3 module with ESP32C3
Type "help()" for more information.

thank you for sharing. The bootloader address is different between ESP32 and ESP32c3.
- ESP32: Bootloader is located at the address 0x1000 in the flash. See here.
- ESP32c3: Bootloader is located at the address 0x0 in the flash. See here.

The difference is because the C3 uses a RISC V core and not an esp32 core.
