Discuss the GoPro Hero3 Black & BacPacs, General, Issues and Trouble Shooting

I hope this helps someone. It's 4AM in the morning, and I'm not really sure of anything right now. But, a forum user was kind enough to send me a half-broken Hero3 Black to experiment on, and finding the UART was interesting. Like the Hero2, you do get an ambsh prompt on the UART, but there aren't any debug messages initially (which I guess saves them time). I used the 'mesg rtos on' and 'dmesg rtos' to get the useful messages. Now, sleep time.

Can you abort the boot process and use bootloader CLI commands?

I think so. The device I tested on was a bit finnicky but shorting TX/RX did the trick at one point. Just don't short them for too long, or you might overflow the input buffer if they don't check for that sort of thing.
