I have been building embedded systems for a while now and I am considering using the beaglebone (BBB) for an upcoming project, but I am confused by everything I read regarding the shutdown requirements. As an embedded system the only way to turn it off is to simply shutdown the power with a switch, yet my preliminary research indicates that this is a no-no as it may damage the BBB and/or corrupt the file system. I also read a lot of comments regarding voltage on the pins after a shutdown; in my case, very likely there will be a CAT5 cable with live activity connected even after power down; assume the magnetics should protect the BBB, but just checking.
I have used quite a few micro controllers and various self-standing systems, but am fairly new to the BBB - still mostly reading about it. Am I missing something? How can a device meant to be used in embedded systems not be tolerant of power loss and be so finicky about power? By the way, I can see there is a battery backup circuit but I do not want to use a lithium battery for safety/temperature/cost reasons. Using a large capacitor also seems tricky as the shutdown may take a few seconds so I don't see how that will work. Any suggestions would be greatly appreciated. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
