R16 tinav2.1常见问题
一）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

二）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

三）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
四）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
