ESP8266 crashes serial connection after Micropython flash
Posted: Thu Mar 02, 2017 1:39 am
This is my first post, and please excuse my lack of knowledge. I'm an engineer and playing with esp8266 applications in making simple IOT WIFI sensor nodes and learning Python. Now to my problem. I have several esp8266 development boards, two with CH340g chips and two with SILAB 2012. All of my boards are Chinese clones. I was able to easily flash micropython on both CH340g boards with my Mac and had no trouble using the ampy utilities to load and manage programs. I have also no issues with the REPL. When I try to do the same on my two 2102 equipped boards, it appears that micropython flashes properly, I get no errors and a message stating it is done. When I try to access the REPL, however, things go bad and the Mac Terminal Screen program crashes. I also tried using a serial application with the same results. As far as I can tell, the problem is related to the 2102 but I've tried everything i can think of and I'm out of ideas. Any help would be very much appreciated. Thanks in advance.

P.S. I wanted to include a picture of my board, but don't believe this forum supports attaching photos...
