楼主
有知道的大拿，指点一下方向，问题出在何处？？？？？不胜感激！！！！！！！！！！
从官网下载的Firefly-RK3399_Android7.1.2_MP_180126 镜像文件包
从官网下载Firefly-RK3399_Android7.1.2_git_20180126.7z 源码包
按照文档说明，将 u-boot/include/configs/rk33plat.h 中的 delay时间从'0' 修改为 '20'
/* mod it to enable console commands. */
#define CONFIG_BOOTDELAY 20
然后将单独编译的uboot的三个文件替换镜像文件包中的同名文件，
uboot.img
trust.img
rk3399_loader_v1.08.109.bin -> 重命名为 MiniLoaderAll.bin
用 mkupdate.bat 脚本再windows下将镜像文件打包成 update.img
最后通过 SD_Firmware_Tool._v1.46 烧录到SD 卡中。
结果还是不如预期，uboot 没有出现等待键盘输入的意思，直接引导kernel 起来，log如下，
