R16 android4.4 常见问题
一）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
二）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
三）默认勾选使用以太网

1)在frameworksbasepackagesSettingsProviderresvaluesdefault.xml
  true  改成true
  true 添加以下这两句
   true
   eth0

2)在frameworksbasepackagesSettingsProvidersrccomandroidproviderssettingsDatabaseHelper.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)
