hi,

i tried compiling the "cf_ide_test" project in the downloaded cdcomponent.zip but got lots of compiling errors; i do not need to install linux , do i ???

have you been able to compile cfcomponent successfully ?

i tried it for 1s40fullfeatured using niosii v1.01 but

got compile errors (see below); did you have to modify

any code (eg how did you# define cf_ide_base , "cf",.... and the file altera_avalon_cf_regs.h is installed but the compile didn't see it)

and which version of niosii you used? maybe v1.01 is too

new?)

thanks # ####################################################

Nope, I didn&#39;t try to compile the project that came with the cf_component. I believe I used linux.ptf for my development board. I don&#39;t know what you&#39;d use for an S40 development board.

Look for the# defines here.

Opinions now, since I don&#39;t have the answer:

Linux has support for the cf&#39;s VFAT filesystem. Your software must support VFAT - not just the IDE interface, but a real live PC-readable filesystem - to use the cf card properly.

Make sense?

Unfortunately, the kernal and filesystem projects I created in November no longer work. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/ohmy.gif How distressing. I&#39;ll be coming back to it next week, I hope.

Maybe one of the experts can get more detailed info for you.
