Subject: Whats missing in my new FB DRM driver... "No connectors reported connected with modes"?
Date: Wed, 30 Dec 2015 18:46:38 +0000	[thread overview]
Message-ID: <5684268E.2000607@synopsys.com> (raw)

Hi guys,

I'm writing a DRM driver for a framebuffer embedded hardware that uses 
an i2c encoder (adv7511), following the basic steps suggested by Laurent 
in "anatomy of an embedded KMS driver": 
https://www.youtube.com/watch?v=Ja8fM7rTae4

After initiliazing all kms, crtc, encoder, i2c, connector functions and 
structures i'm calling drm_fbdev_cma_init to create a fbdev.

When booting i'm getting an error message saying "No connectors reported 
connected with modes", but the driver init is ok and i can find the 
/dev/dri/* and /dev/fb0 devices.

Any clue what i might be missing during the driver load?

Thanks...

Regards,
C.Palminha
