CF interface
When I force safe board configuration on 1C20 dev board - can I expect the default software package in this board to use CF for any purpose? How can I see CF interface activity, not using uCLinux?

Hello,
Sorry but I do not really understand what you would like to do. In which way do you want to use the CF interface? Bye, niosIIuser - Altera_Forum

The "force safe" configuration, from Altera, does not exercise compact flash. Various versions of this design had the interface defined, but none have used it.
Note: what I say may not apply to uClinux; I don't know if they use CF or not. - Altera_Forum

In example Quartus project ("full-featured") I do not see anything going to the proto1_IOxx pins of FPGA, normally connected to Proto1 board and CF interface. I hoped I could see some example app using CF interface on nios II running Micrium OS... Is there anything like that somewhere? Why CF 128M card with a sticker indicating 1C20 board and a version number 1.0 is included in the kit if the kit is not exercising it at all? Where this particular CF is used ? Am I missing something here ?

It shows to have 14.1 Mb capacity, not 128M like I was thinking based on the manufacturer model number (FAW-5020-128). Anybody knows an example of using CF on nios II with micrium or directly, without os? - Altera_Forum

Perhaps the Compact Flash Component from Microtronix would be good starting point for you. Take a look at cf component (http://www.niosforum.com/forum/index.php?act=st&f=16&t=254)

Prior to Nios II.. Nios v3.2, etc., had compact flash defined (but not used) in the factory design (based on standard_32). It was not the best implementation - various PIOs and an interface to user logic. We took that out of Nios II 1.0 because of the component that Microtronix has provided (a much cleaner implementation); as stated above, try out their download. I believe that it includes example designs that define all the pins for you.

Thank you - I will try to play with this component. This forum is very helpful! THANKS.
