Hi all, I've used the my WeMos D1 Mini clone for other projects before, but seems like MicroPython doesn't want to run correctly. I used the following command to flash (from https://docs.micropython.org/en/latest/esp8266/esp8266/tutorial/intro.html#deploying-the-firmware): esptool.py --port /dev/tt...

Hi guys, After a long time i discovered the solution fallowing a friend instructions, to solve this problem i have to compile the micropython firmware. My module still don't work using pre compiled firmwares but when i compile using this tutorial from adafruit( https://learn.adafruit.com/building-an...

After erase board using esptool.py, before set sta_if try to configure webrepl first. I got same error if i set sta_if before configure webrepl.

Hi, i'm getting the same problem with my d1 mini, how exactly you solved your issue? These are the commands: esptool.py --port /dev/tty.wchusbserial1420 --baud 115200 erase_flash esptool.py --port /dev/tty.wchusbserial1420 --baud 115200 write_flash -fm dio --flash_size=detect 0 ~/Downloads/esp8266-...

Are you sure dio is the correct flash mode for that board? Have you tried other modes?

Hi, i just tried now with -dout and still in the same mode. I think its a hardware problem:(

You don't flash firmware correctly.

Im flashing using normal parameters: esptool.py --baud 115200 --port /dev/ttyUSB0 write_flash -fm dio -fs 4MB -ff 40m 0x00000 esp8266-20180325-v1.9.3-477-g7b0a020a.bin

R u connecting at baud rate of 115200??

Yes, and i tried 9600 too but remain the garbage code on serial

Hi guys, I used Micropython in my module before, but now i cant flash a working micropython firmware, while flashing ends the blue led show up and if i connect by serial i get a lot of garbage code. The module works fine with NodeMCU, AT and Arduino Firmwares. i just tried erase flash using esptool....

Erasing the flash then using "-fm dio" did the trick. Thanks!!!
