[PeterYao]

Hello,everyone:

I have a problem, My board is Freescale i.MX 6Quad and i use the BCM4334 wifi ,

But i insmod the driver ,it always cant power on . I think ,kernel should be set up something

ps: My English is very poor...,May be incomplete description.

$ insmod bcmdhd.ko

---------dhd_bus_reg_sdio_notify--------

dhd_customer_gpio_wlan_ctrl(int onoff)

dhd_customer_gpio_wlan_ctrl: call customer specific GPIO to turn on WL_REG_ON

failed to power up wifi chip, retry again (4 left) **

Hi

Can you check 1.8v io voltage & external 32Khz power-on sequence.

In addition wl_reg_on & bt_reg_on must take care for turning on wifi
