The Compact Flash card is directly connected to the MPC8540 bus without the use of a pcmcia adapter. The Compact Flash card is being initialized correctly using the U-boot boot-loader and is working properly as an ide device in U-boot. However I cannot get linux to recognize the ide device. I have tried several different linux config options and have tried passing kernel command line options as advised in the Documentation/ide.txt help file. However I have not been able to get the kernel to recognize my ide device. Does anybody know if I can use the generic linux ide drivers? Or will I need to modify/write my own driver for this type of setup? Any help is greatly appreciated. Regards, Michael Willis Applied Research Labs - University of Texas willis arlut.utexas.edu
