1  R16 android4.4 常见问题1.1  在内核中添加spi驱动

$cd lichee/linux-3.4 $make ARCH=ARM menuconfig $lunch astar_parrot-tina
$make kernel_menuconfig
Device Drivers ---> SPI support ---> <*> User mode SPI device driver support
修改

  

lichee/tools/pack/chips/sun8iw5p1/configs/evb-30/sys_config.fex  

[spi_board0]  

modalias      = "at25df641"  

sflash_size   = 32  

max_speed_hz  = 50000000

bus_num       = 0  

chip_select   = 0  

mode          = 0  

修改成

   

[spi_board0]

modalias      = "spidev"  

sflash_size   = 32  

max_speed_hz  = 50000000  

bus_num       = 0  

chip_select   = 0  

mode          = 0  

1.2  以太网不能用

在内核增加驱动

$make ARCH=arm menuconfig  

Device Drivers --->

   

• Network device support --->  

       USB Network Adapters --->

              <*> Multi-purpose USB Networking Frameworksuch as cable modems)

              <*> SMSC LAN95XX based USB 2.0 10/100 ethernet devices  

1.3  默认勾选使用以太网

1)在frameworks\base\packages\SettingsProvider\res\values\default.xml

  <bool name="def_ethernet_on">true</bool>  改成true

  <bool name="def_ethernet_mode">true</bool> 添加以下这两句  

     <bool name="def_ethernet_conf">true</bool>

      <string name="def_ethernet_IFname" translatable="false">eth0</string>

2)在frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java 添加

       loadBooleanSetting(stmt, Settings.Global.ETHERNET_CONF, R.bool.def_ethernet_conf)

       loadStringSetting(stmt, Settings.Global.ETHERNET_IFNAME, R.string.def_ethernet_ifname)
