    BCM4339 how to check function2 enable fail problem


      Hi all,


      I have tried to porting BCM4339 WiFi driver on my RTOS, but suffered enable SDIO function 2 problem.

      After setting SDIOD_CCCR_IOEN to 0x06, polling SDIOD_CCCR_IORDY value is 0x02, not 0x06.

      How can I check this problem step by step?

      Are there any required hardware or software settings I should do before enabling function 2?
