  Welcome and technical clarifications

The EFIKA has not reached France for the moment ;-), but work is in progress on the project.

I try here to develop a "lite" display interface for the EFIKA dedicated to all people who don't need an expensive & powerful GPU + screen solution. This interface is well suited for basic monitoring (static graphics) & I'm thinking about making an USB powered "fluent" console mode.

PCI is an option today since using this interface involve heavy HW & SW work (why not creating a sort of "synergy/alliance" with similar projects ?). I'm looking at alternative solutions using "more standard" ways to drive small size TFT panels with the EFIKA.

Nevertheless, the primary objective is the USB version for the moment.

You'll find a very nice description of the current development platform on B&R's blog. Thank you for this entry ;-).

Technical clarifications

Last week I discussed by e-mail with Matt and B&R from Genesi to obtain more information on the EFIKA system.

I thought using the "LocalPlus Bus (External Bus Interface)" as a direct interface to the PPC internal bus by disabling the PCI I/F (Normal Mode). But this is clearly impossible since it implies to heavy modification and signals integrity will be badly affected. I also suppose that heavy software modification have to be considered.
Conclusion: this interface is definitively not an option.

Perahps I can find some useful High Speed I/F (PSC) but USB & PCI are the prefered ways for the moment.
