Did you resolve your issue? Do you need any help?
We've worked around the issue by simply not using the define.
However, this issue still exists as of 3.1.1, on a BCM943362WCD4
Just adding a cross-reference to this thread: Are interrupts ever disabled by WICED? where using the WICED_DISABLE_MCU_POWERSAVE macro was suggested. I've tested the macro and confirmed the same behaviour described here -- radio fails to initialize properly following a power-reset when this macro is defined. Tests were performed using BCM943362WCD4, WICED 3.1.2, and "snip.apsta-BCM943362WCD4 download".
