会在/data/dmp_buf/里保存图片数据,假设名为frame0_win0_0_1920x1080_XBGR888.bin
使用7yuv设置好分辨率1920x1080和格式RGBA888就能显示该图片
## 使用Linaro编译器编译
[gcc-linaro-4.9.4-2017.01-i686_aarch64-linux-gnu.tar.xz下载地址](http://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/aarch64-linux-gnu/)
修改对应的gen脚本里的LOCAL_CROSS_COMPILE为指定的编译器即可
### 编译u-boot
烧写u-boot
upgrade_tool di uboot uboot.img
upgrade_tool di trust trust.img
upgrade_tool ul RK3399MiniLoaderAll_V1.05.bin
进入uboot后查看是否是新编译器编译的,执行下面命令
version
结果中能看到如下信息
U-Boot 2014.10-RK3399-10 (Mar 30 2017 - 00:42:40)
aarch64-linux-gnu-gcc (Linaro GCC 4.9-2017.01) 4.9.4
GNU ld (Linaro_Binutils-2017.01) 2.24.0.20141017 Linaro 2014_11-3-git
### 编译kernel
烧写kernel
upgrade_tool di -k kernel.img
upgrade_tool di resource resource.img
查编译内核的编译器版本
cat /proc/version
结果中能看到如下信息
Linux version 4.4.16 (gcc version 4.9.4 (Linaro GCC 4.9-2017.01) )
