Hello everybody, I am using a BeagleBone Black version A6A with Debian distribution on a µSD card.
debian@beaglebone:~$ uname -a Linux beaglebone 3.8.13-bone50 #1 SMP Tue May 13 13:24:52 UTC 2014 armv7l GNU/Linux I want to avoid BBB shutdown during power outage. Therefore a battery backup is directly connected to BBB as described on the following link: BeagleBone Black UPS <http://www.beaglebone-asterisk.org/uninterruptible-power-supply-ups-for-beaglebone-black-a-diy-project/> Unhappily, as soon as a power outage occurs, the BBB performs a clean shutdown within approx. 60 seconds as battery is still connected. In fact, quite a lot of applications must still run during and after power outage. I didn't find in the BBB reference manual and documentation any tips related to "no shutdown" procedure. When Googling, every topic, I could find, is related to the way shutdown occurs. Monitoring battery level before shutdown procedure also exists on some forums but nothing preventing shutdown when a battery backup is available. I must admit that I am not skilled enough to handle very complicate programming tasks. Therefore trying to dig in source code is difficult. I only use Python for basic tasks. I tried Angström distribution installed on the BBB (Rev A6A) and encountered the same shutdown problem when removing 5V DC power supply. There is an interesting Power Cape on the market that may be configured for different BBB behaviours. It is certainly the best solution. But I want to keep budget and power consumption as low as possible. Last comment to avoid misunderstanding: for my application, during power outage, I only need 3.3V power supply...not 5V. Only Ethernet interface and some GPIO are used. Does anyone knows how to avoid this shutdown procedure? Some guidelines would be appreciated Kind regards Michel. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
