全志h6平台在桌面的操作不花屏，桌面右键，其他所有应用打开，在应用上面会出现黑色色块

全志h3到h5系列CPU方案的板子使用5.10以上版本内核HDMI无声怎么解决，实测5.4.88是有声音的

这是我自己编译的uboot2018版本使用sunxi-fel工具启动时的串口信息

@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

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
