Missing /dev/fb0 in yocto image

[piotrlewicki]

Hello.

I'm trying to adapt the freescale image to be able to work with board provided by phytec company and for now I copied their machine.conf and I have changed used kernel (they are using some recipe for "linux-mainline" which is for now v3.19, but I used freescale's "linux-imx"). I attached machine.conf file I use.

My freescale distribution is built from "fido" branch.

I use tftp to obtain the linux kernel and device tree and NFS for root filesystem.

My problem is that I have built the "core-image-sato" and now the system boots but I get :

Freeing unused kernel memory: 328K (80d1c000 - 80d6e000)

INIT: version 2.88 booting

Error opening /dev/fb0: No such file or directory

Starting udev

Could you tell my why I don't have any framebuffers?

What is responsible for it's creation?

Original Attachment has been moved to: file.conf.zip

give me a kernel boot log

I am using imx kernel (3.14) provided by fsl git repository.

I'm sorry but I'm a newbie - what do you mean by "proper kernel command line" ?

I did not understand which kernel you are using, but double check if you have the proper kernel command line to "turn on" the frame buffer in your kernel.
