i got a little problem flashing the custom build via nodemcu-flasher.
After creating a custom build (default + spi) and flashing it, the esp8266 just restarts endless. The blue led is flashing all the time and the serial monitor just shows the same messages over and over again.
Flashing the nodemcu build that comes with the nodemcu-flasher makes not a problem at all.
