Need to reflash the SPI-NOR
Hi , I am using saberlite EVK board and try to boot form SD card. In the below link it is metioned that we need to be reflash board with a small SD card loader to support boot from SD card. https://wiki.linaro.org/Boards/MX6QSabreLite. I did as per the link but it did't work for me. I even does not have MFG tool to flash NOR. Now my board doesnt have any image it seem. it is not booting and serial console, i am not seeing any messages. Please let me where i can get the MFG tool for saberlite and pre-build image to flash my board again. please help. i am deadly need of this.. -- Thanks Regards G.Srinivas Reddy. ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
big.LITTLE MP status Sep 18, 2012
https://wiki.linaro.org/projects/big.LITTLE.MP Blueprint updates: https://blueprints.launchpad.net/linaro-qa/+spec/task-placement-testing * smoke test is completed for cyclictest on Android. * cpu and thread features of sysbench required for scheduler testing currently. * Android port supports those two features * sysbench, cyclictests have been delivered from the Android team. * cyclictest: dropped realtime clock feature in Android, libnuma support removed from Android * ftrace raw data mode vs. txt mode: kernel shark only supports raw data mode. * By using sysbench and cyclictests we can create below listed loads and time interval of running. while running these tests we need to identify mechanism to instrument the kernel to identify and print, the cluster number and core number, duration on test on each core. this instrumentation has been planned at project level. so need to communicate with development team and identify the best tools to trace cpu, threads and time. Roadmap Cards == Technical steering committee are currently reviewing the big.LITTLE MP roadmap cards: http://cards.linaro.org/browse/CARD-189 (Mobile workload generation suite) http://cards.linaro.org/browse/CARD-190 (Improving HMP Linux scheduling) http://cards.linaro.org/browse/CARD-191 (Improving Idle frameworks in Linux) http://cards.linaro.org/browse/CARD-192 (Simplifying power management PULL request for big LITTLE MP v8 branch * Major updates are: * Based on v3.6-rc5 * new branch from * Paulm: rcu-hotplug-v1 * vincent: scheduler-misc-v1 and sudeepk arm-multi_pmu_v1 * new version of patches from Morten: task-placement-v2 * config fragment updated for fast slow cpu ** For more details please see: http://lists.linaro.org/pipermail/linaro-dev/2012-September/013575.html -- David Zinman Linaro Release Manager | Project Manager Linaro.org | Open source software for ARM SoCs ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev

I just moved the condition out from the function and called it when the
condition is true.
if (!drv-power_specified)
set_power_states(drv);
But please, drop this patch too. I noticed there is an overlap with the
next patch I have in my series but not published.
Accidentally I removed cpuidle_curr_driver = drv;
Sorry for the inconvenience. Time for me to go to bed :)

However I find the isim_system is similar to the model_shell, with the same input I set to model_shell, it could launch the simulation finally. Still curious to know why model_shell don't work.

I launch the fast model by below command: model_shell cadi_system_Linux64-Release-GCC-4.4.so Should you be running model_shell64 instead?

So the required command-line for the isim_system binary built by the fast models package should be similar to the examples we document for launching the RTSM binaries. Yes, it is similar.
