是的
有点难度，得在uboot里面实现linux driver里面那个 tftlcd 之类的驱动。

我按照此链接中的步骤在 uboot 上安装了驱动程序。但是在启动到系统时它不显示结果。

有没有办法解决它？或者您需要使用wifi，无论哪种型号都稳定。

r8723bs wifi 能稳定工作吗？

晕哥说：

linux下设置网关有专门的命令:
route add default gw 192.168.0.xxx

我已经设置了网关，但仍然无法ping通。

我将安装 esp8089 但我使用这个命令 modprobe esp8089.ko config=crystal_26M_en=1
为什么会这样？

通常 buildroot 会像这样显示 root。

bin      lib      media    proc     sbin     usr
dev      lib32    mnt      root     sys      var

buildroot 怎么能像这样显示 root ？

bin      lib      media    proc     sbin     usr

那就可以用了，fbv,fbset都可以测试，在buildroot里面有。

Is this mainline buildroot or somebody's port? Which defconfig are you using?
Buildroot 2017.xx is probably unmaintained now so there may be build issues.

I follow this link
I don't know if there are any other links that can be used or not.
