I am actually trying to work with the latest version of Petalinux in my Xilinx Spartan3 development kit. I am quite unexperienced in this sense but I have already solved some problems concerning EDK and building the Petalinux kernel.
What I would like to do now is to develop a graphical user interface in Petalinux (to do this, I will use a graphic library called MiniGUI). This software is basically a C-written program which shows the GUI by means of the framebuffer fbcon. However, I have some doubts about how to do it.
My problems are related to the EDK project. I don't really know if Petalinux will work with any type of VGA IP Core. I mean, will petalinux detect that I have a VGA IP core? That will be enough if I want to use a LCD or a monitor? Because of my lack of knowledge in this sense I don't really get to understand how to do this.
Please if you know any place where some cores are avaliable (or some information about how to build a VGA controller which works in Petalinux) it would be nice of you to tell me.
You will require a framebuffer device driver - they are quite simple to write, with many examples in linux-2.6.x/drivers/video
Which VGA IP core are you using?
