R16 android4.4 常見問題參考手冊

1 R16 android4.4 常見問題

1.1 在內(nèi)核中添加spi驅(qū)動

$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(nèi)核增加驅(qū)動

$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(rèn)勾選使用以太網(wǎng)

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> 添加以下這兩句

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)
