Out of curiosity, what are you using for your development host?

I am using a quite slow, by today's standards, iCore 2 Quad with 8gig, and
it's acceptable. But I don't use the GUI much at all, usually only to produce
the u-boot.mcs when I flash the SPI.

I use an iCore7 at a client I work at during the day, also with 8gig of
memory. Memory is not a constraint, but using a machine with 4gig of memory is
like banging one's head against the wall.

I would also like to get some solid state drives to build on, they are cheap
these days...when I upgrade my system next, it will be getting at least some
solid state drive(s). That will help compile times greatly.

I worked a project that had an embedded device with 4gig of memory and 2 x
32gig solid state drives. It could boot a full blown Ubuntu in just a few
seconds. That one was doing real time video, 30 fps, hooked on a catheter that
gets fished through one's artery from the the leg up to the heart, taking
video while doing so...

That is good to know. When I was having most problems with them, I was at a
startup with kinda shady network, makes me wonder if that is what was going on
with the Vivado tools. I downloaded the latest tools, but have 14.4 on my
system also...

What version of Vivado tools are you using?

Ok, the latest stuff is 2013.4 that I just installed but haven't used it much
as I'm chasing these zynq build problems.

Speaking of which, I'm just going to look at redoing my images. Stay
tuned...news at 11:00 as they say! lol
