Re: [microblaze-uclinux] Downloding image file

["David Montminy" <dpmontminy@xxxxxxxxx>]

Venkatesha,

I've been able to get uClinux to boot on the XUP2VP when I use the
version of the uClinux distribution and kernel in XAPP 934 and 730 and
*do not* update with CVS.  Just add the Petalogix mb-gcc toolchain or
use the one already installed under
/home/devel/uclinux/bin/mb-tools/bin.  Whichever you use, you will
need to add it to your path.

I'm using EDK 8.1.02 so John Williams' XUPV2P reference design
(uclinux-xup2p_rev_1_2.zip) was an easy starting point.  This file
used to be available on the Digilent website, but for some reason they
have reverted back to version 1_1 which was designed for 7.1.  Since
I'm not sure about copyright restrictions, I won't post it here.
Perhaps John could add the latest version to the Petalogix website.

To make sure you tools chain  is set up correctly (and methodology), I
suggest taking the auto-config.in and download_bootloop.bit files from
the zip and running them through the make xconfig; make dep; make
process.  You should get a image.bin file that works.

Occasionally, my uClinux bootup will freeze at the SystemAce drivers,
but I can get it to continue by removing the card then reinserting it.
(Disclaimer:  I'm not sure if this could damage the board or card).

I hope this helps,

David
