Here is a doc describing the two problems I ran into in building the ESP_OPEN_SDK... Once that is done, the tools should build and you can move on to building MicroPython... Basically... - one of the source websites is unavailable (to me) (http://isl.gforge.inria.fr/) - and the version of expat need...

I don't understand the problem this aims to solve. Have you tried building the ESP_OPEN_SDK lately? (https://github.com/pfalcon/esp-open-sdk) It doesn't work. Versions have been updated, files have been moved... it is very difficult... and I've done it many times before! What I am trying to do is m...

I would definitely be interested! BTW... check out the GITHUB status on this...

Thanks for the responses! I guess I should narrow down the topic to be more in line with what I was thinking. What I am really looking for is a simple, start with nothing, procedure/application/package that goes something like this... Install small toolset of scripts with maybe a small GUI Download ...

Just so you know, I just went through the documented steps and ran into only two dependency issues breaking the building of the esp_open_sdk toolkit.

I can document all my steps, here if you still need it.

Otherwise, I think I will format some documentation on the process and post somewhere.

I wanted to tap all the members who have gone through the manual building of MicroPython for the ESP8266. What I am looking for is the best way to build the custom firmware. I am interested in approaches that would make building a custom MicroPython image, not so cumbersome. Anyway, the only approac...

Hello, I can certainly understand any frustration you may have at attempting this, but I am glad to see you giving it some effort. Compiling the firmware (and allowing frozen modules and other modifications) is a very important skillset in the MicroPython world... that unfortunately has not been giv...

Very Nice!
I have been contemplating a similar endeavor for a while now so it's nice to see something come to fruition.

Congratulations and the best of luck to you!

Ye, I like upyCraft.

Here is a good page on the ESPTOOL which all the apps use to do the dirty work.

Especially the Flash Modes on the ESP8266.

Glad you got it solved!

Actually, with a 16MB flash size you should also be flashing an extra file called... esp_init_data_default.bin For example... esptool.py -p COM5 -c esp8266 -b 460800 write_flash -fm dio --flash_size=16MB 0x0000 esp8266-v1.16.bin 0xffc000 esp_init_data_default.bin Is what I used to use for a Wemos D1...
