I am working with the EVK1100. I am working on a project that require me to use both the SD_MMC reader as well as the Display. I got both parts working in separate projects. I then merged my code together and I cannot get them both working. I understand that they both use AVR32_SPI1 and that the Display is cs2 and the SD_MMC is cs1. I try to initialize the Display first then I make a second set of SPI_Options and call SD_MMC_INIT. If i comment out the SD_MMC_INIT the display works, if I leave the SD_MMC_INIT call in the SD_MMC works but the display will not display. Does anyone have any tips to getting these two devices to work together on the SPI bus. I know there is a way I just cannot seem to figure it out. Thank you for any help.

May I suggest the nice tutorial by Chuck Baird, [TUT] SD card initialization and the Butterfly. This is not long.

I solved the very same problem. It was very easy, you can read about it here.
