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
