Problems mounting CompactFlash

I'm Using the Quartus 5.1, Nios 5.1, and eCos for 5.1.

I'm using the project with the CompactFlash support from the Forum.

I have build the Libraries, and compiled the the fileio1.c just fine. I modified the device name to /dev/cfa/0 as indicated in the Readme file. But when I try to run the program from the SDK shell or from the IDE, I always get the same error:

<FAIL> mount() returned -1 unknown error

<FAIL> chdir() returned -1 No such entity

I have also tried /dev/cfa/1, /dev/cfb/0, and /dev/cfb/1 with the same result

    make sure you are not using the lcd and cf on the same i/o pins.

    Also make sure you are using a Quartus project that enables the compact

    flash. I had similar problems until I realized that my project did not set up

    the compact flash component.
