Which git repository for the omap kernel are people using for the latest Power Management features? I am seeing kilman and sakoman. Are there any others?

Hi Tran, kernel version 3.5 works without those errors..! In fact it(V3.5) has no errors at all..! You can try it..!

Hi Sudhangathan, thanks for answering. Are you referring to 3.5 of sakoman's or khilman's? Thanks -- View this message in context: http://gumstix.8.x6.nabble.com/which-repository-for-latest-pm-patches-tp4968198p4968243.html Sent from the Gumstix mailing list archive at Nabble.com. |

Thanks!!! I can sleep now in kernel 3.5 of khilman's. I did have to unload the module g_ether before sleeping. Also I wasn't seeing much power savings. Must be missing something. But at least I am closer now thanks to you (sleep and wake-up works). 270mA @ 3.3v when awake 250mA @ 3.3v when sleep Thanks -- View this message in context: http://gumstix.8.x6.nabble.com/which-repository-for-latest-pm-patches-tp4968198p4968248.html Sent from the Gumstix mailing list archive at Nabble.com. |

That seems like quite a high draw for sleep...what precisely is being turned off in this scenario? On Fri, Nov 15, 2013 at 9:53 AM, dtran11 <dt...@gm...> wrote: > Thanks!!!

Hi Tran, 270mA or even 250mA is way too high.. I get 190mA without any tweaks.. I'm using Overo-Fire and summit hardware. You can recompile the kernel after enabling sleep while idle or opportunistic sleep in the kernel configuration. bitbake -c menuconfig virtual/kernel Also try turning off wifi and usb chips. If you are using overo, this might work straight away for you. echo 0 > /sys/class/gpio/gpio16/value Also try enabling cpu-freq flags in kernel configuration, and try bringing down frequency of operation..! Aim for about 90mA after all this.!! All the best..!! :) --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 --------------------------------- On Fri, Nov 15, 2013 at 4:23 AM, dtran11 <dt...@gm...> wrote: > Thanks!!!

Hi again Tran, Take some tips from here too.. These instruction are for kernel 2.6.39PM, But a few things work for 3.5 too..!! http://wiki.gumstix.org/index.php?title=Category:How_to_-_Low_Power --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 Bangalore. --------------------------------- On Fri, Nov 15, 2013 at 11:40 AM, Sudhangathan B S <sud...@gm...>wrote: > Hi Tran, > > 270mA or even 250mA is way too high..
