R16 android4.4 常见问题

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

2.设备信息配置文件

设备信息配置文件：lichee/tools/pack/chips/sun8iw5p1/configs/evb-30/sys_config.fex

3.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

4.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)
