Re: [microblaze-uclinux] Fwd: Troubleshooting installation of ICAP drivers

["David Montminy" <dpmontminy@xxxxxxxxx>]

Thank you for your help, I think I'm back on track now.  I was under
the impression that the ICAP drivers were already part of the uClinux
distribution and the patch altered the drivers.  I now understand that
the patch only alters one file and adds a handful of new files.

patch -p0 < icap.diff     (this did the trick)

Although the CentOS distrubution (from XAPP730) has a uClinux
distribution/kernel installed, you still need to follow the steps the
Petalogix website to install the MicroBlaze GCC toolchain before
kernel will successfully compile. It can be found here:

I hope this is helpful for anyone trying to using this application note.

Thanks,

David
