1  R16 android4.4 常見(jiàn)問(wèn)題
1.1  在內核中添加spi驅動(dòng)
$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  以太網(wǎng)不能用
在內核增加驅動(dòng)

$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  默認勾選使用以太網(wǎng)
1)在frameworks\base\packages\SettingsProvider\res\values\default.xml
  true  改成true
  true 添加以下這兩句  
     true
      eth0

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)
