ESP8266 Community Forum

I've done some research on the bootloader protocol, and I'm working on a simple python utility to download firmware to RAM and Flash, so we can avoid XTCOM.
I hope that the community will create a great open, cross-platform utility to support custom firmware on the ESP8266.

Here's my stuff so far:

Great work, thanks for sharing!

Is there any clear guide on how to connect up the device for access to this debugging interface?

As written here viewtopic.php?f=5&t=7&start=10#p73 by Squonk and others, booting with GPIO0 pulled down makes to boot ROM to enter UART mode. It'll then talk at normal 115200 8N1.
I'll add a note on the github project.
