Linaro 13.06

Hi I running Linaro Android 13.06 (Android 4.2.2) on TI's panda Board.But while running Android cts 4.2.2 ,i am some 50 plus issues related to different cts packages. Even 30 issues are related to Mediastress say "Test failed to run. Test run failed due to : Instrumentation run failed due to 'java.lang.RuntimeException" by running run cts --class android.mediastress.cts.H264R480pAacShortPlayerTest What is the reason behind the failure. Is it the package is not supported by linaro 13.06

Thank you in Advance !!!!
