NodeMCU D1 Mini board won't boot, won't flash
Posted: Wed Aug 15, 2018 11:57 am
I have a D1 Mini that had been working fine. After uploading a small change to a file, it would not boot.
The serial output at 74880 baud is simply this:
After that no response.
I tried to re-flash NodeMCI with PyFlasher.
It shows this output
After that nothing.
If I select "Erase Flash" the last status reported is
I've let it sit for hours, and it never proceeds beyond that message.
What is the next step to resolve?
