  • Target HW boards
    • i.MX50 EVK 
    • i.MX53 SABRE Tablet
    • i.MX51 EVK
  • What we got in this release:
    • Base version is upgraded to android-2.3.4_rc1
    • CTS 2.3_r4 (i.MX53 SABRE Tablet only)
      • One time run.
        • 13610 CTS case can be finished in one test cycle for most running.
        • There is still possibility that CTS is stopped in following cases.
          • USB cable need be reconnected: This is a known issue in CTS tool, which we have reported to Google.
          • board freeze during reboot(<5%):Root cause still uncertain.
        • Pass rate
          • i.MX53 TABLET ---- 3 failure cases left among all 13610 cases
            •  1 failure is caused by CTS case itself, which has been reported to Google CTS community.
            •  2 failures are caused by the cellular network condition. These two cases are for 3G which failed to retrieve SMS delivery report within 5 minutes for fragmented long SMS.
        • Note: CTS result depends on many factors
          • Tested Target (i.e. HW board, SW running on it)
            The above pass rate (3 failure cases) is tested with specified test target (i.MX53 TABLET + Android R10.3 SW).
            When running CTS on different target (e.g. on customer's board, or with modified SW), you may get various CTS result
          • Environment (i.e. cellular/wifi network condition, network configuration, HW board stability, etc)
            Even with same test target (i.e. same HW+SW), run CTS several times may get various result. For example, those 2 3G related failures cases above may pass sometimes.
      • Add some new features
