ESP8266-12F does not work at all

General

After building most recent firmware locally with:
mos build --local --clean --arch esp8266

…and flashing with command:
mos flash

the system is unable to boot properly and goes into an endless loop, here are the logs:

How about mos flash esp8266 && mos console ?

#3

The same result like before.

#4

It appears you’re the only one with this problem.

Try another hardware.

Finally figured it out. It was an insufficient power/voltage issue, which was discussed here already. Please take care to power your board with proper source, the serial programmer power is not enough for normal operation :frowning:
