Upgrading ESP-8266-01 to current using nodemcu-build.com

I've got couple of ESP8266 -01 version (cheapest ones form Aliexpress) - it's the one with two GPIOs. Running 0.9.6-dev latest, but having issues with decimial readaing below zero using DHT22 library - I decided to update to integer build from http://nodemcu-build.com/. All I do is add DHT22 to default settings, buid - either dev or master - but after flashing with esptool.py the script fails right after 100%, and the ESP unit is in crash-loop. I can still go back to original 0.9.6dev NodeMCU flash but - why is it crashing ?

Hi, did you find the solution to the problem?
I have the same issue with a ESP-01 black...

Thanks!

You need to set all 'write_flash' parameters correctly and also flash esp init data (unless you're on the dev branch), see http://nodemcu.readthedocs.io/en/master ... g-firmware for details.
