To program the XP10, I use a parallel port JTAG cable and Lattice tools. I think others have used the USB cables just fine too. Alas, I do this part and the synthesis under Windows. For the S3, we have a tool in the repo that programs an SPI PROM connected to the XP10. On power-up, the XP10 programs the S3 in slave serial mode. So, so recap, here are the things you have to do, some optional: (1) Synthesize for the XP10. This requires the "free" Lattice tools. (2) Program the XP10. You need the Lattice tool for this and a JTAG cable. On the board, I see these labels on the header: + G I O S C (2) Synthesize for the S3. This requires the commercial version of ISE. But we have a bitfile that we can mail you. (3) Program the S3. We have a program for Linux in the repo for this. (4) Build the BIOS. The bugs in this process should be worked out. Make /opt world writable, and this will go smoother. Mark can help with that. (5) Program the BIOS. Another tool in the repo. There isn't documentation on how to do this synthesis, and can't think of all of the things you need to know. Start with the XP10 top level and start bringing in modules from that directory and I think just the pci directory until all of the dependencies are satisfied. There is a constraints file in there, and it's very important. _IF_ you are going to do this, start on it sooner rather than later in case we forgot to check something in. Mark did most of the BIOS, and Petter did most of the HQ microcode, so they should be able to help us out with any problems. I found Howard's original email to me on the latest S3 image. I've dropped the image at: http://www.cse.ohio-state.edu/~millerti/mod.bit And the command to program it is: ./s3_prom_load device mod.bit And I think "device" here means the PCI bus ID you get from lspci. > > > > > I was hoping to get time this weekend to get my own build > > environment set up here, but I'm too busy preparing for the WEED > > 2009 workshop at ISCA this weekend.
