jianke512 说：晕哥，在Kernel的log中已确认console=ttyS0,与你在一楼推荐的CONFIG_BOOTARGS设置一样
另外Kernel version 4.14
困扰中参考1: https://whycan.cn/t_2388.html (荔枝派zero/小智极客S3/V3s使用sunxi-fel 借 u-boot 启动 Linux系统, 无需 spi flash / TF 卡)
参考这个帖子， 一个一个替换文件, 逐步排除问题。
Hi，
晕哥，此问题解决，参考以下链接的改法OK了，谢谢
https://www.lotlab.org/2018/07/28/record-of-using-licheepi-zero-part-1-u-boot-linux-buildroot/
晕哥，现在调试LecheePi Zero，屏幕800x480，已按照1楼的配置更改UBOOT，kernel用的800x480的dtb，启动过程中UBOOT屏幕可以显示，linux kernel屏幕不显示并且kernel hang住，请帮忙给些调试建议
