Yes,the idea is to use the Ghidra decompiler to ease reversing new parts of the FlashAir firmware.

The MeP-c4 datasheet is available at https://www.datasheetarchive.com/pdf/download.php?id=6693e80...

I had success compiling GCC with MeP support using git and the commit before the removal. Yet, I believe that FlashAir are not compiled with gcc.

The video will likely be online soon.

The card can already do that. It can connect to an AP and you can already push files thanks to Lua.

Links added! Thanks for the feedback.
