SAMa5D2 DRM driver

Thu Jan 26, 2017 2:51 pm

Hello.
I am trying to build a Yocto image including the DRM driver.
I have tried the core-image-minimal, the core-image-x11 and similar (including the atmel-xplained-lcd-demo-image and the qt5 image)

None of the resulting images has the /dev/dri or /dev/fb0 devices.
I suppose I am doing something wrong.

I following the instructions at:
linux4sam/bin/view/Linux4SAM/Sama5d2XplainedMainPage

The prebuilt sd-card images on linux4sam/bin/view/Linux4SAM/Sama5d2XplainedMainPage
works fine, so my sama5d2 board seems ok.

I am using a TM7000 display.

I hope someone can give me some hints.

Drivers are part of the kernel.
The DRM driver is enabled in meta-atmel/recipes-kernel/linux/linux-at91-4.4/sama5/defconfig at line 190+

Assuming that changes were minor since 29/10/2016 when I built the Linux4SAM 5.5 demo, how did you obtain a "core-image-x11"?
