Hello! If you don't mind the top-posting, please see the quoted chain of emails below. Summary is that some changes need to make it to the omapzoom.org kernel for Zoom2. Greetings!

Both kernel changes and those bootargs are required. -----Original Message----- From: Turquette, Mike Sent: Monday, February 16, 2009 10:32 AM To: Jimenez Villareal, Omar; Mande, Nikhil; Diaz, Daniel; Castaneda Gonzalez, Axel; Munoz, Jose Luis Diaz Subject: RE: omap24xxvout alloc DMA page failed when using openMAX This is probably unrelated, but I saw in another thread by Lajos that it is necessary to set omap24xxfb:rotation=0 in the bootargs to avoid some errors when specifically using the Zoom2 board. Obviously a rotation of 0 is the default, but Lajos said it had to be specifically set to avoid some sort of issue. Maybe related, maybe not.
