- Fri Oct 19, 2018 3:14 pm #78751 Hello everyone,
I'm facing a strange issue. I'm trying to flash an ESP12E, if I flash it using Arduino IDE it seems to flash it, but after a reboot doesn't work. If I take the binary produced by Arduino's compiler and flash it using nodemcu-pyflasher it works! I seem to use the same flashing parameters in both softwares: flashing mode set to DIO, flash size set to 4M and upload speed set to 115200. The only difference I see is that in Arduino I have to specify board type and I set it to "generic esp8266 module". Any idea/suggestion to make it work with Arduino IDE?
Thanks for your help

- Sat Oct 20, 2018 3:16 am #78758 Have you ticked the Show verbose output during upload in Arduino preferences?

That will give more detail on how esptool is being invoked and may give more of a clue as to what is going on?

I normally use espuino as the board for esp-12 modules as they normally should support QIO flashing.

If it appears to upload correctly but doesn't run, have you tried giving it a separate second reset? Some upload methods may not be invoking the correct reset procedure.

- Mon Oct 22, 2018 11:33 am #78798 Thank you for your reply. Manually resetting the board via the rst pin or power cycling it doesn't change anything. I've enabled the verbose output and here's the part about the flashing:

So there's a warning but I don't know how to interpret it, maybe just a problem while connecting to the board that then recovered?

- Tue Oct 23, 2018 11:34 am #78822 Don't know what the warning is.

My output is similar but with no warning plus some extra lines at the end (if you included everything.
