1、蓝牙调试
主要是蓝牙的I2C地址跟 地磁仪的I2C地址冲突，被地磁仪给占用了，改回来就好了。

2、wifi调试
之前打开wifi 一直打印出下面的log.

从ath6kl: Unable to enable sdio func 可以看出来是 SDIO初始化没有成功，，高通打电话的回复是，我们代码中设置的SDIO模式和接口跟硬件连接对应不上。
please check codekernel/arch/arm/mach-msm/board-msm7x27.c (does your board use this file,please confirm it)check sdcc related configuration. eg msm7x2x_sdc2_data
然后硬件把主板上面WIFI的晶振去掉后，使用8X25Q自带的晶振，后面打出下面的LOG.

这样说明SDIO起来的。但是还是不成功，用示源器量了adio_clk引脚也是有波形的。
因为我们只有一块主板上面接了LCD和TP可以点击连接WIFI。
后面有个同事查到 用命令也可以打开WIFI。
打开WIFI:svc wifi enable
关闭WIFI:svc wifi disable
然后再打开另一个终端可以看到log. 确认WIFI打开正常。
唯有讲述此间途经的美景，分享没有男主角的相片。
