全志 Tina Linux 存储介质切换：eMMC，SPI NAND，SPI NOR，SD Card，SD NAND
存储切换方法
SDK切换存储介质需要修改board.dts、sys_config.fex、内核配置、TINA系统配置。另外，在spinor 存储介质下，通过 u-boot-sun8iw21p1.bin 进行烧录，u-boot-spinor-sun8iw21p1.bin 启动，使用sys_partition_nor.fex作为分区表。在非spinor介质(spinand、emmc、sdnand)，通过u-boot-sun8iw21p1.bin进行烧录和启动，使用sys_partition.fex作为分区表。下文将介绍spinor切换spinand、spinand切换spinor、spinor切换emmc、spinor切换sdnand四种切换方式。
- sys_config.fex中只要关注storage_type选项，这个选项决定使用哪一种存储介质，配置后在pack过程，会自动打包对应介质的二进制文件。
[target]
storage_type = xxx
其中storage_type | 0:nand | 1:sd | 2:emmc | 3:spinor | 4:emmc3 | 5:spinand | 6:sd1 |
spinor切换spinand
sys_config.fex修改
[target]
- storage_type = 3
+ storage_type = 5
board.dts/uboot-board.dts修改
&spi0 {
- status = "disabled";
+ status = "okay";
spi-nand@0 {
- status="disabled";
+ status="okay";
};
};
uboot编译
编译u-boot-sun8iw21p1.bin，spinand使用u-boot-sun8iw21p1.bin进行烧录、启动。
cboot切换到uboot目录，编辑configs/sun8iw21p1_defconfig
CONFIG_SUNXI_UBIFS=y //SDK发布默认已选上
执行mboot //编译
确保device/config/chips/vxxx/bin/u-boot-sun8iw21p1.bin已更新

Tina 一般支持nor, nand, mmc 三种介质。
更具体的，nand分为并口nand和spinand，mmc分emmc和sd卡
主要需要区分的是nor和其他介质，因为需要打包的部分有所不同。
即，emmc和nand，sd卡一般可共用一份固件，而nor则需使用另一份固件
sys_config配置
在sys_config中有一个配置项，storage_type，取值及含义如下
;----------------------------------------------------------------------------------
; storage_type 0:nand 1:sd 2:emmc 3:spinor 4:emmc3 5:spinand 6:sd1
;----------------------------------------------------------------------------------
[target]
storage_type = xxx
对于nor的方案，必须配置为
storage_type = 3
对于其他介质，storage_type则不能配置为3
spinand切换为spinor
sys_config 设置介质为nor
[target]
storage_type = 3
配置所用nor的大小
[norflash]
size = 16

注意点
对于nand，rootfs_data分区，使用ext4格式。分配太小的话可能会创建失败。
FAQ
使用mkfs.ext4等工具的时候出现
/usr/sbin/fsck.ext4 -y /dev/by-name/rootfs_data
Error loading shared library /home/wuguanling/workspace/project/v316-sdv-tina/out/v316-sdv/staging_dir/target/rootfs/lib/libc.so: No such file or directory (needed by /usr/lib/libext2fs.so.2)
关闭以下选项：
make menuconfig

| --- []strip unnecessary functions for libraries
