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)
