CompactFlash support

Hi all, I try to put in operation the CompactFlash in my development kit, but during the compilation of uClinux source I have this errors :

I follow this (http://www.nioswiki.com/operatingsystems/uclinux/compactflash) . Has someone resolved this problem ?

Sorry for my bad english and thanks in advice.

    Hi,

    I have exactly the same error, did you manage to fix this problem?

    Should update the library libata? (Kernel : 2.6.23-uc)

    Thanks,

    Hi all,

    Here is the error message when compiling :

    CC drivers/ata/libata-core.o

    Should defined ioread8, ioread16 ... in asm/io.h?

    # define ioread8(X) readb(X)# define ioread16(X) readw(X)

    ...

    What is the kernel configuration for the compact flash?

    I followed the instructions given in nioswiki : http://www.nioswiki.com/operatingsystems/u...ux/compactflash (http://www.nioswiki.com/operatingsystems/uclinux/compactflash)

    Thanks,
