Adafruit Feather Huzzah esp8266 not running MicroPython
I am trying to put the MicroPython firmware on my new feather Huzzah and I can flash the firmware fine and it seems to be successful but when I go to start the REPL in PuTTY I am getting a weird flashing line. I have attached some screenshots from flashing, PuTTY configs. and PuTTY console. I was able to flash it with CircuitPython and it worked fine but for some reason MicroPython is not working.

The speed in your putty config looks correct, but every time I've seen the writings of Cthulhu in a terminal when attempting a serial connection it was because I had the speed wrong.
Re: Adafruit Feather Huzzah esp8266 not running MicroPython
Probably not the reason, but have you tried using the latest version, v1.11?
If you press enter a few times at the terminal, does the prompt appear?

Yeah, I've tried both versions and tried enter a few times in the console. Nothing seems to respond in the PuTTY console.

And you've tries ctrl-c also?
Hrmm... I wonder... did you do an erase_flash before programming? Might be worth trying?

I guess I didn't try ctl-c. I'll have to try that later (I'm at work now haha). I did erase the flash and re-flashed multiple times.

Did you switch flow control in Putty off?
Re: Adafruit Feather Huzzah esp8266 not running MicroPython
I have not messed with the flow control at all. currently it is set to XON/XOFF. Are you saying maybe I should try no flow control? I'm not sure what RTS/CTS or DSR/DTR actually are.

Set it to no glow control.

That did it for me. Thank you!
