    Disabling MCU power save and AMPDU

    cary.wong_1798781

      Recently ran into a problem after migrating to 3.1.0 from 2.4.1

       

      When WICED_DISABLE_MCU_POWERSAVE is defined, power-cycling the board will bring it into a state shown below:

      Starting WICED v3.1.0

      Platform BCM943362WCD4 initialised

      Started ThreadX v5.6

      Initialising NetX v5.7_sp1

      Creating Packet pools

      Could not set AMPDU parameters

      Error 2 while starting WICED!

       

      The application used is snip/apsta (same behaviour on other applications)

       

      I am not sure whether this is related to platform restructuring in 3.1.0, and whether this is intentional/intended behaviour. My suspicion comes from the following statement in WICED/WWD/internal/chips/43362A2/wwd_ap.c:

           "For SDK 3.0, and beyond, each chip will need it's own function for setting AMPDU parameters."

       

      Any ideas, tips, or pointers to better understand the problem and why it's behaving this way is greatly appreciated.
