Hi again, Even though Yocto finally builds and boots my Overo, I am yet not satisfied. I seek a kernel with good power efficiency, i.e., I need to tweak the Power Management. I find a lot of references to kernel 2.6.38/39, and even 3.0, of Sakoman, that was tailored for PM, so these builds have _pm as extension. Using legacy OpenEmbedded, I have not managed to make these boot by Overo, even the pre-built kernels did not. My host computer is Ubuntu 12.04, and I have learned the lesson that OpenEmbedded do not work for this platform. So, either I have to setup a new host computer and Ubuntu 10.04, or I try Yocto. So, I ended up with Yocto, and have finally made it compile and boot on the Overo platform (see my previous mail). So, the question is this: * where should I seek information in order to build Yocto (which is only Linux 3.2 as far as I can tell) with the PM tools as e.g. specified in http://elinux.org/OMAP_Power_Management and http://wiki.gumstix.org/index.php?title=Category:How_to_-_Low_Power ? Hoping for some advice. :) Best regards Arne Lie SINTEF ICT |

Of course you can use different kernel versions with Yocto, just add a recipe. I believe the Gumsix Yocto repo uses 3.5 by default. I think Sakoman uses 3.6, but I'm not sure. Check those repos for example recipes. Like others, the instructions on my page are primarily for my use, so I default to the kernel that suits me. -- View this message in context: http://gumstix.8.n6.nabble.com/Yocto-Gumstix-Overo-and-Power-Management-tp4966436p4966439.html Sent from the Gumstix mailing list archive at Nabble.com. |

Hm, I guess I have to invest some more time in the Yocto architecture before moving any further. But thanks for the tips, I will investigate and post results when done.

Also note that when asked, Steve indicated that enough PM patches had been upstreamed that he would no longer have a PM branch. So, the answer may be that you simple don't need a special kernel anymore- I'd dig under /sys and see what was there.
