1  R16 tinav2.1常见问题
1.1  分区
修改target/allwinner/astar-parrot/configs/sys_partition.fex
例如：
    [partition]
    name        = rootfs_data
    size        = 12582912
    user_type    = 0x8000
修改其中的size属性，单位: 扇区。
如要修改成1G，计算方法如下
size = 1024 * 1024 * 1024 / 512

1.2  把文件打包到rootfs
将文件放到package/base-files/files目录下即可。如果文件过大，在pack时报错，修改分区表的rootfs分区的大小

1.3  增加spi
1) 在内核中添加spi 驱动
$cd tinaV2.1
$source build/envsetup.sh
$lunch astar_parrot-tina
$make kernel_menuconfig  
Device Drivers --->
SPI support --->
<*> User mode SPI device driver support  
2) 修改
tinaV2.1/target/allwinner/astar-parrot/configs/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

1.4  以太网不可用
$cd tinaV2.1
$make kernel_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
