What distro are you using with the BBB?
I'm surprised that you're having so much trouble with the rPi. I've had an
original Model-B running continuously for the past 2 years without
rebooting (VK5ZM-5 Rx Only iGate), it currently runs a full AX25 stack and
aprx. The only negative thing I'll say regarding the Pi's is make sure
you're power supply is 5V with NO detectable ripple at 1A output (so <
20mV); otherwise there will be tears.
I also just recently built two more APRS iGates using the latest Model-A's
and a pair of tncPi's. Both of these are working with the latest version
I'd firstly check the 5V supply that you're feeding the rPi with, make sure
it's clean and not drooping under load. If you can still find one the
Geekroo Echidna PSU shields (http://www.geekroo.com.au/products/526) are
not a bad way of powering your Pi. You can find them a little cheaper
around the traps if you search. I'll see how small I can compress and
image of my current SD card and if I can sensibly upload it somewhere on
the net, if that will help?
The vast amount of rPi stability issues can be traced to the power supply,
this is the best place to start. Let me know if you need any more help
sorting your Pi out.
