rv1126 image update 打包
RK SDK中的img镜像都是gpt格式的，分区又很多，为了看起来直观，方便管理，只用三个分区就够了，uboot、kernel、rootfs。这里记录下linux和windows下两种打包img方式。
linux打包
1.修改分区
修改sdk/device/rockchip/rv1126_rv1109/parameter-ubuntu.txt文件，删除misc、recovery等分区

2.修改打包脚本
文件系统用的是自己构建出来的，没有用sdk中的rootfs.img，
修改sdk/tools/linux/Linux_Pack_Firmware/rockdev/rv1126_rv1109-package-file文件
--- a/tools/linux/Linux_Pack_Firmware/rockdev/rv1126_rv1109-package-file

3.实现
在SDK目录下执行./build.sh firmware && ./build.sh updateimg后就按照自定义分区格式生成了升级固件update.img
