（二）出现的问题

[drivers/video/console/vgacon.o] error 1
[drivers/video/console] Error 2
[drivers/video]Error 2

——————————————————

drivers/video/console/vgacon.c: In function 'vgacon_startup':...

当我们都配置好以后执行make uImage时，出现了以下的错误信息，根据信息的大概意思是关于vga的支持问题，在这里我直接把关于vga的配置选项去掉不选

Device Drivers

---->Graphics support

----->Console display driver support

----->VGA text Console(这个选项不选就能解决此问题)
