      如题,使用uboot源码编译获得的u-boot-with-spl.bin写入emmc或sd卡8k的位置上无法引导,同时,编译获得的二进制文件可以使用sunxi-fel的uboot命令在板子上面运行,使用emmc原本的引导程序,上电输出hello boot0 is starting 这段程序执行完后跳到u-boot-2011版本继续执行引导内核的任务

          @yuzukitsuru 将uboot-2018烧写到emmc过后,上电直接进fel模式,用sunxi-fel启动uboot-2018功能一切正常,能识别各种设备,包括emmc,但是用2018年版本后的uboot,就不能正常识别emmc了,用的defconfig是cubietruck_plus的
