Very true. So I guess even just using a li-po or li-ion on the bone would
be much easier.

I've connected beagleboneblack to my car power supply with 24V to 5V step

BBB stops running and don reboot though the power led is on. Can I fix it
with software change mentioned at
The reason it powers off is because your ignition switch is not providing
constant power when you turn the key to start. I would try to find a power
source that has power when key is set to on and start.

Ok so why not add a cap to the circuit to keep it powered while you start
the car.

cap? is it some electronic circuitry? I donno much abt electronic circuits
but i can solder few resistors, capacitors and diods on a board. Any help
is a gr8 favour..
Thank you.

Cap = capacitor. Just make sure that it is the right size for where you put
it in your circuit. If it is too small i can explode and possibly start a
fire. In your original post you stated that you have a 24V to 5V step down,
so if you place it before the step down make sure it is at least rated
Thank you. I will give a try. As per the post here
https://groups.google.com/forum/#!msg/beagleboard/aXv6An1xfqI/mURD3LfQ5dMJ?
the power source should have proper rise time. I'm afraid a capacitor will
increase the rise time. Any way I'll give a try.

24V power supply in a car? If this means you're this from the accessories
circuit, you're doomed. Accessories are turned off while the car is being
started, and a cap won't be enough to power the beaglebone, since
Not necessarily , my car is a 95 3kgt and it starts within 1-2 seconds of
turning it over. A cap big enough should be able to handle that. As for the
24v idk how I didn't catch that, but then again who knows it is possible.

Not sure if I did my math right, but for 2 seconds at 2W (beaglebone will
be booting), and assuming his 24V to 5V regulator can regulate with an
input voltage all the way down to 12V, that's around 20mF. I guess that's
doable with $$$.
It wouldn't
