[beagleboard] Re: Monitor Line Current with UPS

Hi Trevor, My first thought would be to use a UPS that provides a Power HID device over USB. It's safe and *should* be simple. I haven't messed with it but there is Linux software for monitoring and reporting UPS status. The "ghetto" way would be to use an opto-isolated zero-crossing type

[beagleboard] Re: Does not detect RTC (ds1307)

The kernel driver isn't seeing the RTC. If it did, it would have claimed the I2C address and there would be "UU" in it's place instead of the address. You're either missing the correct kernel driver for your RTC or the device tree isn't set up for this scenario. I don't use any RTC parts so

Hi all, First off, I agree with the need for a UPS and power control cape - that's why I created the Power Cape. The firmware and schematics are available online (yes, I do know that's not truly OSH). Back on topic, I think Jason is looking for an existing OSH design that wouldn't otherwise

Re: [beagleboard] BBB don't boot sometimes

You definitely need a supply that can generate enough current to have a decent ramp-up of 5V or the PMIC gets angry. But, there's also the issue of u-boot stopping if it sees a "phantom character" from the UART. So, if you need high reliability start-up you should rebuild u-boot for "keyed

Re: [beagleboard] Turning Off the Power management Beagle Bone Black

Hi all, My original reasoning behind the Power Cape was to get a 5V supply with a low quiescent off current and that could restart the BeagleBone on a scheduled timeout or external event. Using a 5V supply instead of the PMIC's battery interface also allows for using USB devices. The battery

Re: [beagleboard] Improper Power Down....All Revisions - Is this still an issue?

The Power Cape http://andicelabs.com/beaglebone-powercape/ will perform automatic switch-over to a battery on DC power failure. A script can monitor DC power good over I2C and shut the system down as required (I usually wait until the battery hits 3V since power here is usually restored

Hi Rico, Any reason that you can't use a cape to solve the problem? The PowerCape http://elinux.org/AndiceLabs:PowerCape will prevent brown-outs and transients from bringing the BB down. Your application/script can monitor DC power good and battery voltage/current and then do a clean

attach to the same i2c pins as your cape EEPROM. Given the pcb cad files I'm guessing it would take 5-10 minutes tops to add a RTC to your board and getting the software to use it another hour tops. Eric On Mon, Apr 14, 2014 at 8:54 AM, Ron B. r...@andicelabs.com javascript: wrote: Hi

I do a lot of BBB work with 1S, 2S, and 3S LiPo packs. Remember, the lower the voltage the higher the current requirements are going to be on the batteries. Pretty sure that I've run from a 2xAA alkaline pack but I know that the LiPos can easily supply the current. During boot I've seen
