aodzip 说：

Linux 5.4.35是通过测试的版本，试一下

吐了 用5.3 5.6都不行  又得下个5.4

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。

我看了一下，我对应的Makefile只有这些内容啊

另外  eth0的那个问题的命令 会报错的

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

有个read flash error,我的Flash型号是w25q128fvsg,但我下载xboot是正常的，不知道什么原因。

这样可以用MDK + JLink单步调试吗？调试器会自动加载gcc编译elf文件吗？
