ESP8266 broken?

Post by Rhiza » Sat Oct 08, 2016 7:30 am

Hi guys, new member here. I just got my ESP8266 Huzzah board in the mail the other day and I instantly tried to install micropython.
I use the tutorial by the Micropyton team, and also tried Adafruits tutorial. Everything runs smoothly and without errors until I actually try to connect to the board over usb.
I've tried using screen on linux and putty on windows and I don't see a REPL only gibberish.
Is it possible that my board is fried? I tried deleting the flash and reinstalling without success. Using ubuntu or windows makes no difference.

Hard to say without knowing what you are doing exactly.

Is the baud rate set to 115200?

Did you connect GPIO0 to GND (you don't need to do that on the Feather Huzzah) and forgot to disconnect it?

Another possibility is that you may have power problems: the ESP uses a significant amount of current. Use a short USB lead and if possible check the voltage on the board. USB outlets should be capable of supplying 500mA at 5V, but it's not unknown for them to be out of spec.

I bet with Robert, this looks pretty much like the wrong baud settings.
BTW. I started to use picocom which works very well. Esp. it does not interrupt when the connection is lost. Which makes it very usefull during boot-up and reboot cycles.
