Hi Philipp, I did U-BOOT driver for emaclite. You can set both ping pong mode - all combination are supported. I tested this driver with Microblaze and works well. I use this driver almost every day and I have no problem with it. If you have problem with this driver please send your email to u-boot mailing list.
