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?
I think you should check on the 'get_modes' call back of adv7511 driver. (Or, if possible show us the code.)
Best,

Thanks...
