Antti, a binary demo may not be useful to you, but it's obviously of some value
to the people who've been asking for it, and the numerous people who've
downloaded it in the just last 12 hours.

One reason binary demos are valuable is for people who want a quick evaluation,
a proof of concept, or even just be able to show their boss that indeed Linux on
an FPGA works, and might make sense for their project. They don't want to take
the time to learn how to build it themselves, they just want the "5 minute
demo", and that's what this is about.

One of the goals of PetaLinux, of course, is to enable people to build the
5-minute demo themselves, as well as provide an environment for major FPGA-based
embedded Linux development. This is a lofty goal, which is why it's taking a
while to get it developed and documented to a state where we are happy to
release it.

Yes, we do have early access to the 8.2 tools, and indeed the current demo is
based on 8.1. Why? Because as a small organisation operating out of a
university research group we have limited resources which we must manage
carefully.

We also have paying clients who expect us to deliver what we have promised. If
this means that PetaLinux, and other nice-to-have features that we will be
giving aware free to the community (including you) must sometimes take a
back-seat, then I can make no apologies for that fact.

Regards,

John

Hi John,

ok, I see while you are busy with paying clients you have no longer
interest to work on mb-uclinux improvement. Good point. That is
possible the reason why Xilinx did choose lynuxworks to deliver the
microblaze 2.6.x port.

For those who want to use GPL tools to compile MicroBlaze 5.0
applications on WinXP platform here is the cygwin compiled MicroBlaze
toolchain from EDK 8.2 release.

http://www.xilant.com/downloads/mb_gnu_8_2.zip

I have only tested it to succesfully compile MicroBlaze u-boot, so the
toolchain is working at least.

I'm speechless. You win.

Digilent has a 3S1600E board out right now:

http://www.digilentinc.com/Products/Detail.cfm?Prod=S3E1600&Nav1=Products&Nav2=Programmable

The best part is, they actually fixed some of the gripes I had about
the previous 3S500E board.

Antti,

Is there somewhere I can download the source for this? I'd like to
modify it to drop its xil dependancy:

/cygdrive/f/hw/mbgcc/bin/../lib/gcc/microblaze/3.4.1/../../../../microblaze/bin/ld:
cannot find -lxil

Thanks,
Todd
