Centos7 编译Android7.1_Industry烧录后启动错误

szzhangzhen

Centos7安装必要的开发环境后，执行
./FFTools/make.sh  -d rk3399-firefly-face-mipi8 -j8 -l rk3399_firefly_face-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3399_firefly_face-userdebug
完成编译，烧录固件后，启动失败，串口输出

提示fdt，error，使用官方镜像解包后的resource.img，单独下载，启动成功
请问，出现此问题原因是

已经使用  git clone https://gitlab.com/TeeFirefly/rk3399-industry-nougat-bundle.git .bundle
.bundle/update
git rebase FETCH_HEAD
同步至最新
单独编译kernel，发现dtb无法打包至resource
，
导致，resource.img只有2K

又安装了一下编译依赖，问题解决，具体是哪个编译依赖导致，未知{:5_241:}

这个问题，在编译其他厂家提供的Android8.1，再一次出现，安装各种编译环境依赖仍无法解决，花了2天时间，终于定位到了问题所在，解决方法如下：
1、编译Kernel，出现：E/get_file_size(316): Failed to get size
E/get_file_size(316): Failed to get size:./arch/arm/boot/dts/pro-rk3288.dtb
E/get_file_size(316): Failed to get size:./arch/arm/boot/dts/pro-rk3288.dtb
E/get_file_size(316): Failed to get size:logo.bmp
E/get_file_size(316): Failed to get size:logo.bmp
E/get_file_size(316): Failed to get size:logo_kernel.bmp
E/get_file_size(316): Failed to get size:logo_kernel.bmp

追踪源码发现，为resource_tool.c下的stat函数获取文件长度失败导致
（原因：部分平台不支持stat64，需将gcc编译命令加上-D_FILE_OFFSET_BITS=64）

解决方法：
cd u-boot/tools/resource_tool
vim Makefile

- #CFLAGS = -fshort-wchar -m32 -ffunction-sections -Os
+ CFLAGS = -D_FILE_OFFSET_BITS=64 -fshort-wchar -m32 -ffunction-sections -Os

重新编译resource_tool，编译后的resource_tool替换kernel/scripts/resource_tool即可
然后./build.sh kernel  重新编译内核
