求助！求助！Linux内核启动显示屏不打印。

happy粥 · 2022-04-26 10:43:32

第一次发帖，可能有说不明白的，希望有大佬前辈能指点一下。

U-Boot能够启动，并且在显示屏上能够显示logo，显示屏选择的是480X272的，文件include/configs/sun8i.h也已经修改了。
U-Boot引导进入启动Linux内核后就出现了以下这种情况。设备树编译选择的是sun8i-v3s-licheepi-zero-with-480x272-lcd.dtb(这个设备树是我下载荔枝派的Linux文件复制到自己下载的Linux-5.15版本内的)
然后就会白屏或者黑屏。奇奇怪怪的。
板子是自己画的一个测试板

这是启动代码。
