On pandaboard.org you will find the Omap4 reference manual. This contains
all the bits and pieces you need.
Writing a framebuffer driver for the Pandaboard includes multiple steps.
First you need to power on all
required subsystems (HDMI, display). Then you will need the GPIO subsystem
to configure the involved
components (e.g. DDC). Configuring the framebuffer itself consists of only a
few steps, however they may
be hard to grasp from the manual.
Thanks for yor reply!
Having searched information about the driver, I still didn't know where to add the driver, L4Re? L4Linux?
Where should I put my drvier to? Are there exist examples of drivers I can refer to?
I think the fb-drv package is a good starting point. However you can put your driver into its own package if you like. To plugin nicely with the existing parts of the L4Re userland (e.g. mag) your driver needs to implement the Goos video API.
