Hello there,
are there any plans to support the Overo COM platform again by Linaro ?
After a long time of experimentation I got the 11.07 release running
stable but the kernel sources are missing so I can't compile some
system drivers.
In the repositories the last log says that last changes have been made
in april.
This lack of support or ongoing development let me question if Linaro
is the easy-to-use/easy-to-upgrade Ubuntu-like solution it seemed to
be at first view. In my project I try to find a next-generation base
platform for our robotic systems and I and especially the following
students don't have time and experience to use a self-configured linux
like with open-embedded or else.
What are your suggestions to do regarding the ongoing plans at Linaro?
Steffen

Hi Guys,
I have struggled today for some time to soft-reset panda board because
the switch S1 (PWRON_RESET) resets the board, but doesn't
start booting it again from xloader. Prompt simply hangs !!
My kernel was crashing after uncompressing linux... print. I didn't
had a debugger
to see value of __log_buf variable. So i wanted to soft reset the board and
check content of memory at address pointed by __log_buf.
I wanted to keep the contents of RAM as it is, so can't reboot it by unplugging
the power cable.
At last i found the trick to soft-reset the board with help of S1
button. Following
are the steps:
- Press S1 once, LED D1 will switch off
- remove SD card
- reinsert the card
- Press S1 again, LED D1 will switch on and board is rebooted, keeping RAM's
contents as is.
Hope, this will help somebody in future.

Hi Andy,
I am using Panda board with linaro Nano filesystem over SDHC card. When i
issue "reboot" command from prompt, it hangs:
root@linaro-nano:/# reboot
Broadcast message from root@linaro-nano
(/dev/ttyO2) at 4:44 ...
The system is going down for reboot NOW!
root@linaro-nano:/# [ 668.889892] Restarting system.
Is this a know issue?

Hi Andrey,
Below is pull request for v7 of MP work. Following are the main changes:
- Based on v3.6-rc3
- per-task-load-average-v3
- applied ARM-Add-HMP-scheduling-support-for-ARM-architecture to
task-placement-v1 branch
- applied Tixy's patch from fast-slow-cpu-dt-v1 to
task-placement-v1 as they are
somewhat related only.
NOTE: Compile tested only
In future i will be sending you PULL requests according to:

Hi,
When trying to checkout the kernel used for Linaro 12.07 on Pandaboard for
Android, the required kernel revision does no longer exist in the remote
git repository (it was there up till about ~2 weeks ago).
Here is what I'm doing, based on the instructions in the Linaro 12.07 build
for Android/Pandaboard<https://android-build.linaro.org/builds/~linaro-android/panda-ics-gcc47-til…>page:
1. Checkout branch *linaro-android-12.07-release* from *git://
android.git.linaro.org/platform/manifest.git*
2. Clone kernel from its location as stated in* tracking-panda.xml*:
*git clone git://android.git.linaro.org/kernel/panda kernel*
3. Checkout kernel revision stated in *tracking-panda.xml*:
*git checkout -b my_branch 1010fcd033e01ead0d43d61d30b341b0d4c68d49*
I get error:
*fatal: reference is not a tree: 1010fcd033e01ead0d43d61d30b341b0d4c68d49*
Clearly, repo sync fails as well.
What change needs to be done to the tracking-panda.xml manifest / kernel
revision to checkout a correct revision?

Thanks a lot Rafael for taking the time to write this demo code.
It is very interesting and probably what should do in the other cpuidle
drivers.
Thanks

This patch sets contains two patches:
[PATCH 1/2] Thermal: Move struct thermal_cooling_device_instance to thermal.h
Note:
Declaration of struct thermal_cooling_device_instance should be moved to public
header file thermal.h, because a thermal zone driver need to operate the cooling
devices binded to itself sometimes, for example when the thermal mode is set to
"disabled", all the cooling devices should be disabled too. This can be done in
thermal_sys.c, but it is better to let the user to do it because different kinds
of cooling devices may have different behavors.
There is no need to maintain a cooling device list by the thermal driver, because
the framework has already done so in the list thermal_zone_device->cooling_devices.
Thus the thermal_cooling_device_instance is needed when a thermal driver walks
throuth the list thermal_zone_device->cooling_devices.
[PATCH 2/2] Thermal: Add ST-Ericsson db8500 thermal dirver.
Updated:
1. Device tree is supported.
2. thermal_zone_device_register() updated because of framework update in
kernel v3.6-rc1
3. Force cooling deveces to be disabled when thermal mode is disabled.
Dependences:
1. Lee Jones PRCMU device tree bindings.
2. Acception of the above thermal framewrok modification.
