Anyone have experience with modifying the firmware in Ambarella a5s cameras?

Most of the guides I've found (for GoPro models) say that the bootloader prompt can be interrupted, although this one just immediately prints "booting from primary partition" and after around 30 seconds something like a MAC address.

@th nope (not yet at least), I have that chip in a old project I might take out of the boxes at some point (cloud spycam I tore down : in french). I'd be interested if find ways to hack them.

@arthurlutzim this one doesn't print any sort of useful messages on the debug uart, so I'm going to try reading/writing the TSOP48 NAND flash directly with an in-system programming clip.
