Hello everyone,
I have connected a 3,7V cell Battery to the Beaglebone Black.
The problem is that every time I unplug the main 5V power supply from the
board, the board is going into a safe shutdown mode (since the battery
still supplies the board with power).
Is there a way to disable this
Hey Bruno,
regarding your Step 3) Try ip link set can0 up type can bitrate 125000

After this Step send some CAN Messages to the Controller and enter ifconfig

the device read any messages (RX entry)
Hi Robert, did you ever get this to work? If so, would you mind sharing

I just went through this same thing a couple days ago. From what I can
tell (and others, please correct me if I'm wrong), there are two different
types of images. One just runs off the SD card (which I am guessing is
what you are using); the other is configured to actually flash the image
onto

that 1 s boot times should be achievable. Scroll down to liyaoshi's posts

Awesome, thanks for the links!

Thanks, William. Yeah, it could be from hibernate, but I don't think so:

Rick, If we're talking uboot- executable, no Linux, you can probably do
the same. One of the beagleboard.org google group community liyoshi I
think had a Qt app booting in under 5 seconds too I think. It's been a

tty0 should be ttyS0 now I believe. Where this is changed with images using
systemd I am not sure, but with SYSV this was changed in /etc/inittab.

I'm working on reducing the boot time (power on to my C user code running) as

Does anyone have any idea how much overhead is introduced by the DTB
processing? If I were to remove the DTB support in a custom kernel,

I would think hard coding into the main DTB would add time. A couple ways
to think about it would be you *could* theoretically in userspace after the
board has booted. Then systemd is supposed to be better at parallel tasks
when booting compared to SYSV. Which again *could* mean that keeping
