It would be possible to upload apps and do programming, but a search seems to indicate
you would have to write the code to do it. OS install I have my doubts because the wifi
drivers, etc.. you would have to get a kernel of some sort loaded then the drivers for wifi,
it looks like great deal of work.
You could always think about using an ESP32 to manage the upload and programming,
if you can get your hooks into the external flash....if thats used.
