Just a quick note – as a few of you have said you’ve had issues flashing ESP boards and some have worked then not worked etc… ensure you use the relevant pull ups and pull downs and the right voltages.  As you know I do a LOT of work with ESP-01, ESP-12, ESP-12E and I can say I have NEVER broken one!  So look for other problems than broken FLASH I suggest??

  1. It’s not outside of reason for some folks to have a reallly marginal flash part in their $2.59 board. Stumble against the wrong mumble opcode, and the processor goes into the weeds.
