with the unannounced changes DJI did, I think there will be more interest in this.

it has both ambarella cpu/priorietary os (camera stuff) and TI DM365 (lightbridge transmission, maybe flight control)
The TI software runs with a lot of GPL things, that DJI are violating the license of by not releasing, IIRC. While illegal, this is rather typical these days though.
