制作升级包：

一、整包升级包制作

以tina4.0 A133 b3版型为例

在/target/allwinner/a133-b6/swupdate或者

target/allwinner/generic/swupdate/目录添加如下文件

1.非安全固件

sw-subimgs-ab.cfg

swota_file_list=(
target/allwinner/generic/swupdate/sw-description-ab:sw-description
out/${TARGET_BOARD}/uboot.img:uboot
out/${TARGET_BOARD}/boot0.img:boot0
out/${TARGET_BOARD}/boot.img:kernel
out/${TARGET_BOARD}/rootfs.img:rootfs
)

 升级指令：swupdate_pack_swu -ab

2.安全固件

sw-subimgs-ab-secure.cfg

swota_file_list=(
target/allwinner/generic/swupdate/sw-description-ab:sw-description
out/${TARGET_BOARD}/image/rootfs.fex:rootfs
out/${TARGET_BOARD}/image/toc1.fex:uboot
out/${TARGET_BOARD}/image/toc0.fex:boot0
out/${TARGET_BOARD}/image/boot.fex:kernel
)

升级指令：swupdate_pack_swu -ab-secure

制作成功log：

3.注意制作失败案例

swupdate_pack_swu -ab

###storage type error###


###cannot choose boot0, please config storage_type in sys_config ###

说明sys_config.fex没指定具体的storage_type

sys_config.fex文件改 storage_type     = 1即可

二、差分包升级包制作

.fw_printenv命令

root@TinaLinux:/# fw_printenv
bootdelay=0
bootcmd=run setargs_nand boot_normal
earlyprintk=sunxi-uart,0x05000000
initcall_debug=0
console=ttyS0,1500000

rdinit=/rdinit
loglevel=8
cma=32M

wifi_mac=
bt_mac=
specialstr=
keybox_list=rpmb_key,dm_crypt_key
trace_buf_size=64M
trace_event=sched_wakeup,sched_switch,sched_blocked_reason,sched_cpu_hotplug,block,ext4
trace_enable=0
setargs_nand=setenv bootargs console=${console} root=${nand_root} rootwait init=${init} rdinit=${rdinit} loglevel=${loglevel}  earlyprintk=${earlyprintk} initcall_debug=${initcall_debug}  loglevel=${logleve
l} partitions=${partitions} cma=${cma} gpt=1 rootfstype=ext4
setargs_mmc=setenv bootargs console=${console} root=${mmc_root} rootwait init=${init} rdinit=${rdinit} loglevel=${loglevel} earlyprintk=${earlyprintk} initcall_debug=${initcall_debug} loglevel=${loglevel} p

boot_normal=sunxi_flash read 45000000 ${boot_partition};bootm 45000000
boot_recovery=sunxi_flash read 45000000 recovery;bootm 45000000
boot_fastboot=fastboot
boot_partition=bootB
root_partition=rootfsB
systemAB_next=B
swu_next=reboot

手动切换到B系统

fw_setenv boot_partition bootB
fw_setenv root_partition rootfsB
