[A9G] How to create firmare and upload it to the board?

Hi there,
I try to run Micropytnon on A9G.
I have found on github the project by pulkin
https://github.com/pulkin/micropython
I understand that firstly I need to burn firmware with Micropython and than upload only "py" files to the board.
Could you tell in general how to run any py-program on it?
The Terra incognito is how to make firmware or where to get it, and which program should I use for uploading?
Thanks in advance,
Victor

One question, which µC is running on your A9G? Never heard about A9G.
Did you try the readme on this
https://github.com/pulkin/micropython/t ... ts/gprs_a9 or this
https://github.com/nk2IsHere/micropytho ... ts/gprs_a9?
I just started with ESP8266 and Micropython. I had to read a lot. There is so much documentation in the net, so almost every beginner question was asked before
it was fun cause even me got it running.

I hadn't come across that port - or that GPRS device. It looks super interesting! Compact, with GPS and runs MicroPython? Awesome.
Anyway, the clue I think you may need is that in that fork by pulkin, the
ports page has a README that links to
AiThinker documentation explaining how to 'burn'.
Once MicroPython is running on the device it appears that you'll be able to use the regular serial interface to communicate to the device and transfer files.

Interesting part, but I wouldn't choose A9G. The AiThinker page says A9G uses a RDA8955 MCU. I didn't find anything about this MCU, no datasheeet, nothing. RDA Microelectronics Inc. was bought by Unisoc
https://en.wikipedia.org/wiki/Unisoc I didn't find anything about A9G on the Unisoc page
https://www.unisoc.com/en_us/#/home/main Best page I found is this
https://github.com/Ai-Thinker-Open/GPRS_C_SDK
This contains maybe the datasheet
http://bbs.ntpcb.com/read-htm-tid-135987.html but my Chinese is way too rusted
I'm not able to register.

I have used this board for quite sometimes. It's cool and very cheap. the A9 GPRS is 4.5$.
I use this repos:
https://github.com/pulkin/micropython
I spent a lot of time on this board. There're some issues with this board, however it fit my project's goal.
