Pico and ESP8266

i have the same problem, my findings so far:

• seems to be a faulty flash chip
  
• does not interfere with the function of the ESP8266
  
  • try it out, with AT commands i can join a network etc.
    
• does not work with the current Espruino ESP8266 module
  
• i tried to flash another firmware, no success so far
  
  
  

.. in the end i gave up for now and ordered some ESP8266 ESP-01 from ebay, look for "tested", i am still waiting for them to arrive
