Hello, I am starting with the course “MicroPython Programming with ESP32 and ESP8266 eBook”. I use the “Wemos D1 Mini” and “MH-ET Live Mini Lit” boards for the ease of stacking components without additional wiring.
I have to questions about them:
- None of these boards has the “BOOT / FLASH” button, so I do not know how to flash the firmware and erase the flash memory.
How can I do this task?
- Once flashed/uploaded the MicroPython firmware it is posible to go back? I mean it is possible to get back the original board state for using it again with the Arduino IDE?
I’m sorry. I jumped the uPyCraft IDE chapter to the Thonny one and did not read the note saying ” flashing your boards with MicroPython is reversible”.
Hello Paul, but were you able to erase the firmware and flash it with MicroPython?
Hi Rui, I’d like to try both: the ESP8266 Wemos D1 Mini and the ESP32 MH-ET Live Mini Kit. No one of them has the BOOT/Flash button, just the RESET one.
Those boards probably already go into boot mode automatically (without having to hold down the button). If you try to erase the flash and flash the MicroPython firmware. Does it work?
Hello Rui, you’re right, it works without the BOOT / FLASH bot. I tried both boards and they go well.
