Micropyton 1.14 doesn't work on Lolin D1 mini Pro v2 (esp8266)

closedby fe328opened 2021-02-10updated 2021-02-11

After flashing 1.14 the board doesn't work (can't enter REPL), blue led continuously blinks.
Same board works fine with 1.13.

I'm a bit of new to this, so I lack knowledge to debug this problem.
What info would be helpful?
