连接电脑，串口打印uboot以及linux内核启动信息，
屏幕一开始嘿嘿的，接着雪花花屏一闪而过，最后黑屏，同时左上角光标不停闪烁。

输入以下内容，屏幕有反应，但是都是雪花点点。。。

echo "Hello" > /dev/fb0
cat /dev/random > /dev/fb0
sl > /dev/fb0

有图为证：

输入以下内容，屏幕正常显示。。。

echo "Hello" > /dev/tty0
cat /dev/random > /dev/tty0
sl > /dev/tty0

有图为证：

***************************************************
测试framebuffer：

root#pi: ~/fb-test
root#pi: ~/mplayer cc.mp4

有图为证：

***************************************************************

想不明白啊 。
内核启动的时候，屏幕为何没有打印启动信息，偏偏是花屏一闪而过。
输入"echo ‘Hello， World！！！！！！！！！！！‘  > /dev/fb0",屏幕显示若干个光点。。
莫非字符内容全部显示为光点了？

这是什么原因啊。；？

设备树写对了吗？？？？？？？？？？？？？？？？？？

        
请大佬指教。。。。
本人初学linux ,深感亚历山大啊。。。

Re: F1c100s是否成功启动SPI屏(st7789v)!？

bootargs console 改为 fb0才行吧

试过了没用。。。。
bootargs :   console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw
bootcmd:    load mmc 0:1 0x80008000 zImage;load mmc 0:1 0x80c08000 suniv-f1c100s.deb; bootz 0x80008000 - 0x80c08000

Re: F1c100s是否成功启动SPI屏(st7789v)!？

试着输入下列代码看看。。。。。

=>setenv bootargs "console=tty0 console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw  vt.global_cursor_default=0"
=>saveenv

此时编译的linux是可以在SPI屏和串口同时输出log的，但是SPI屏端还不是控制台，无法使用USB键盘进行控制!!!!

关键之处在于这个文件/etc/inittab

我在这里面注释了console这一行语句。
添加了下面两行：；

ttyS0::respawn:-/bin/sh
tty0::respawn:-bin/sh

还是不能实现SPI屏被键盘控制字符输入。。。。。
大家有没有办法啊？？？

Re: F1c100s是否成功启动SPI屏(st7789v)!？

usb键盘? 这个有点复杂吧?

首先确保你的usb键盘工作正常，用evtest测试，然后还要做别的处理才行。

晚上试试看，，，只有这样，才是一台小电脑啊。。。哈哈。。。。。
