V3S禁用屏幕log,用于显示qt

rt
我做的V3S板子,可以正常启动linux系统,可以正常进入系统,只不过屏幕显示内核log,然后串口也有打印,通过串口输入指令cat /dev/random > /dev/fb0不能让屏幕花屏,估计是屏幕用于提示登录被占用了吧,如何禁用显示器shell呢
ps:有朋友说坑网有现成的教程,奈何表达能力不到位不知道如何搜索,输入屏幕+禁用或者屏幕+log 都得不到想要的结果

如果你用的是荔枝派uboot 2017的话,在 include/configs/sun8i.h 修改bootargs参数。

是荔枝派2017uboot的
需要添加什么参数呢,目前我只添加了这个(图中我选中的部分,其他的没有,因为接我的不一样),然后重新烧录,屏幕确实不提示登录了,但还是不能到内核禁用屏幕log

这个没问题, 是uboot加载环境变量出错, 他就用了默认参数.

楼主, 你的kernel到底啥时候编译的? 2020-11-20?

楼主, 你的kernel到底啥时候编译的? 2020-11-20?

我刚刚换了 5.2的kernel
日志发现一句Setting up a 800x480 lcd console (overscan 0x0)感觉是罪魁祸首,但是不知道如何消除掉
还得请问各位大佬
另外还发现一个问题,读取的是带dock的那个设备树,为啥ifconfig查不到eth0呢

奉上dtb文件,没有改动过,荔枝派内核5.2分支的原版

Re: V3S禁用屏幕log,用于显示qt

修改这个文件:drivers/video/console/Makefile
#obj-$(CONFIG_FRAMEBUFFER_CONSOLE) += fbcon.o bitblit.o softcursor.o  这行屏蔽掉
#obj-$(CONFIG_FRAMEBUFFER_CONSOLE)     += tileblit.o 这行也屏蔽掉

然后重新编译,亲测可行。

楼主, 你的kernel到底啥时候编译的? 2020-11-20?

我刚刚换了 5.2的kernel
日志发现一句Setting up a 800x480 lcd console (overscan 0x0)感觉是罪魁祸首,但是不知道如何消除掉
还得请问各位大佬
另外还发现一个问题,读取的是带dock的那个设备树,为啥ifconfig查不到eth0呢

奉上dtb文件,没有改动过,荔枝派内核5.2分支的原版

Re: V3S禁用屏幕log,用于显示qt

忙着折腾 说:

修改这个文件:drivers/video/console/Makefile
#obj-$(CONFIG_FRAMEBUFFER_CONSOLE) += fbcon.o bitblit.o softcursor.o  这行屏蔽掉
#obj-$(CONFIG_FRAMEBUFFER_CONSOLE)     += tileblit.o 这行也屏蔽掉

然后重新编译,亲测可行。

好的好的  马上就尝试一下,非常感谢
另外楼上你说的,ifconfig -a都看不到eth0,执行你说的那个命令,恐怕不行吧
ps:板子没在手边 稍后试一下

我看了一下,我对应的Makefile只有这些内容啊

我用的是SPI的屏幕,改了下面3个文件。

可能是你修改drivers/video/console/Makefile这个文件后,就不会生成原来并口RGB的fb0了(我也不知道这样改fb0会消失),你用的是并口RGB屏,而我又启用了SPI屏的驱动,又生成了fb0,我用的是SPI屏。
