Help Identifying ARM SOC?
« on: August 03, 2021, 04:51:05 pm »
Long time EEVblog forum lurker, but new user here...

I'm working on some hardware hacking projects with DJI FPV hardware. We are poking at the DJI/Caddx air units. The common perception is that DJI developed their own proprietary SOC for these devices. According to uname, it is an A7L, which corresponds to an Ambarella chip family, but the ballout looks different to anything I can find online. I'm curious if anyone can ID what this SOC might be, based on the BGA arrangement.

It's probably a shot in the dark, but I figured if anyone might be able to they would be on here. [attachimg=1]

That implies it's running Linux, and you have a shell on it? If so, please post the boot log.
