Can anyone suggest the best evm board for virtex-4 and linux? How has people's experience been with it? Are USB drivers included in the linux os builds they provide? Thanks, Clark

There are possible other boards or modules with partial USB support, but with device and host (OTG) support already included I doubt that you find anything at the moment, you can possible find something with host support only Antti

Thanks. But that brings up another question: Is it better to go with ucLinux or use the PPC version of linux? I suspect the latter if I have the FX part, right?

Unless you are prepared to shell out a reasonable number of dollars to MontaVista, developing for uClinux with the free tools is a lot easier than PPC. There are some guides out there on DIY Linux for Xilinx PPC, but they aren't for the faint-hearted. The board port/bringup procedure for uClinux on MicroBlaze is also a lot faster than PPC Linux, with the free auto-config tools. It depends on what you are trying to do, and how much you value your time. Is this a hobbyist, study or commercial project?

This is a commercial project. I was under the impression Xilinx provides a working Linux build for the V4? I don't expect to be doing much Linux hacking per se, maybe just a custom device driver to interface to my DSP circuit/code.

That is because of Xilinx politics - everybody who is not MontaVista gets just ignored - DENX was doing lots of work towards PPC linux support but as Xilinx did not talk to them so Denx dropped any further work on Xilinx support for PPC linux. Thats too bad. Setting up a new MicroBlaze uCLinux systems is just a piece of cake So if you need some DSP code setup uClinux/Microblaze, connect your DSP functions to FSL links and you are all set -- Antti Lukats http://www.xilant.com

So if I have an FX12 part, for example, your suggestion is that I run uclinux in a soft core and implement my DSP code in the PPC core? This is the opposite of what I had expected. What do I give up for ucLinux versus PPC Linux? Speed? Device driver support? Also, what's your suggestion for unit control? I imagined a webserver interfaced to some type of CGI. Maybe perl scripts or php? Thanks, Clark
