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spi1) 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 = 32max_speed_hz = 50000000bus_num = 0chip_select = 0mode = 0
修改成
[spi_board0]modalias = "spidev"sflash_size = 32max_speed_hz = 50000000bus_num = 0chip_select = 0mode = 0
四）以太网不可用$cd tinaV2.1$make kernel_menuconfigDevice 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
