I add a `udlfb` module into the edison-yocto image, according to the Kconfig:
tristate "Displaylink USB Framebuffer support"
depends on FB && USB
This is a kernel framebuffer driver for DisplayLink USB devices.
Supports fbdev clients like xf86-video-fbdev, kdrive, fbi, and
mplayer -vo fbdev. Supports all USB 2.0 era DisplayLink devices.
To compile as a module, choose M here: the module name is udlfb.
But when I run `modprobe` on the edison board, it gives me :
./udlfb.ko | grep depend
and it shows me that the module depends on fb_sys_fops,sysfillrect,syscopyarea,sysimgblt, and I have already run 'modprobe' one by one. What should I do ？
You said you ran modprobe on all the dependencies. Did you build these dependencies or you just added them to the image?
What other changes have you made to the kernel?
