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,
