Stefan, I'm the initiator of the question. I use the Epson chip in big endian mode. The problem is that in 16 bpp mode, the RGB mapping into video memory is fixed by the chip and described in little endian format. By the way, I really studied the chip and if I want to be able to manage both 8 bpp and 16 bpp mode, I need to be able to change the endianness attribute of the memory region.
Why wouldn't you access video memory via a sthbrx instruction (writew)? Regards, -- Matt Porter porter@cox.net This is Linux Country. On a quiet night, you can hear Windows reboot. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
