Compact Flash Problem

Hi: I am evaluating the Compact Flash IP Core using the Altera Nios Develoment Kit Cyclone 1C20 Edition and I cannot properly access the CF card. I modified the "standard" design example ...

Nir,

Did this card work at all with the previous CF component in an older Nios design, or when attached to a PC with CF card reader? If so we have a problem that was not caught! If you have an older design to try that it works on, I would be interested in seeing it for comparison sake (you have my email address).

Also, what kind of card is it? Do you know which PIO mode?

Back to your question at hand... no, in my tests I haven't come across a card that worked while stepping (debug) but then failed when you just ran it.
