Very simple question.
My ESP spits out constant rubbish on UART after flashing.
I tried different bauds, but doesn't ever get readable.
I did an erase flash, flashed nodeMCU firmware.
Reflashed empty loop, ...
The problem started after getting an error with esptool flashing: digest error or something similar.
The only error I can imagine is a pointer writed out of range and something happened.
