CF operation

Make sure the LCD module is not plugged in to the demo board.

ucLinux can access the CF card like an IDE drive when it's properly hooked up. For that, you'll need to start with one of the demo projects, like "full_featured", add the CompactFlash component to the SOPC builder, and hook up the pins properly (refer to the data sheet for your demo board to find out which Stratix pins hook up to which CF pins). Then work through the ucLinux on Nios manual.

eCos may be able to deal with CF, but I can't help you on that, since I haven't done CF on eCos.

Writing your own CF IDE/ATA driver for Altera HAL is possible, but difficult, and you're on your own.

And please try not to use heavily-styled text like that. Thanks!
