Don't know yet :). Information about this topic was confusing, so first step was to prove that the BBB and a Li-Po battery can keep the RTC alive. El divendres 18 de juliol de 2014 20:43:40 UTC+2, William Hermans va escriure: edugalvez, I must have missed that post, or the post predates

Re: [beagleboard] Re: BeagleBone Black RTC?

Ok. I was not trying to be smart, but was curious. I am still learning a lot about the beaglebone black myself, AND we're offgrid here ( solar and wind ) so this kind of topic generally peaks my interest. On Mon, Jul 21, 2014 at 10:14 AM, Edu Galvez edugalvez.eir...@gmail.com wrote: William,

Hi, I just managed to put the PMIC in SLEEP state, and the AM335x in RTC_Only state. It has been done using u-boot, based on Matt (https://groups.google.com/d/msg/beagleboard/K7DuusrJ6G4/unH1m5HpiuoJ) explanation: *U-Boot# i2c mw 24 a 00 * *--- Send 0x00 to PMIC* *U-Boot# base 44e3e000*

edugalvez, I must have missed that post, or the post predates me on these groups. Thanks for sharing, this is very good to know. Truly. On the other side of the coin, how is this useful once you're running Linux ? Perhaps /dev/mem ? On Fri, Jul 18, 2014 at 12:29 AM, edugalvez.eir...@gmail.com

Hi David, Yes, I have also seen small boards from Adafruit, though if I need an RTC and it is possible to implement a fully functional one with the current board by just adding a battery, I wouldn't add any extra components, especially since the RTC in the CPU seems to have wake up events. I

Fisher, good luck, as Gerald said, making it work is going to be an extreme challenge, which is why we specifically created the RTC Cape. Dave On Monday, July 7, 2014 11:04:24 AM UTC-5, Fisher Grubb wrote: Hi David, Yes, I have also seen small boards from Adafruit, though if I need an RTC

Re: [beagleboard] Re: BeagleBone Black RTC?

External RTC is the best solution. You could add a battery to the BBB and use it with the right SW. But, depending on how many days you want it to hold time, it may or may not work for you. Gerald On Mon, Jul 7, 2014 at 11:04 AM, Fisher Grubb fisher.gr...@gmail.com wrote: Hi David, Yes, I

Re: [beagleboard] Re: BeagleBone Black RTC?

Hi Dave and Gerald, I don't have one of these boards yet so just wanted to check as I am assessing the BBB and comparing it to others for my university project. If it is physically possible to add a rechargeable battery to the PMIC for it to power the board and be charged when external power
