Hi John,
Here is a link to download the omap-pm recipes for the overo that
I've created so far. http://web.me.com/elvis.dowson/Download/OpenEmbedded/Entries/2009/8/3_Power_management_for_gumstix_Overo.html
Let me know if you have any problems building these recipes.
These recipes were original created for the corresponding android
kernel builds, and I just removed the android patches from them.
So, you will have to do
bitbake -c menuconfig linux-omap3-2.6.29
load the defconfig file in the linux-omap3-2.6.29/overo folder, and
then save it back, to remove the android specific kernel configuration
settings.
In the linux-omap3-2.6.29/overo/backup/defconfig folder, you will find
various work in progress defconfig settings.
Let me know how it goes.
Oh, I forgot one more thing, in the linux-omap3-2.6.29.bb recipe, for
the mmc there are three patches
# > OMAP Patches \
file://omap/0300-mmc-clk.patch;patch=1 \
# file://omap/0301-mmc-off-mode-1.patch;patch=1 \
file://omap/0302-mmc-off-mode-2.patch;patch=1 \
Both mmc-off-mode-1 and mmc-off-mode-2 patches are similar, and I
don't know which one to use. I was building mmc-off-mode-2 patch, but
did test it yet and zipped it in a hurry.
if you modify it as follows:
# > OMAP Patches \
file://omap/0300-mmc-clk.patch;patch=1 \
file://omap/0301-mmc-off-mode-1.patch;patch=1 \
# file://omap/0302-mmc-off-mode-2.patch;patch=1 \
It should work fine, and all power domains will reach their target
state. However, at the moment, it takes a couple of seconds for the
system to come back from suspend mode.
Let me know how it goes.
Best regards,
Elvis
