Part 11 – porting to the Turbo Chameleon 64

After porting the Minimig core to my ebay-acquired Cyclone III board, I’ve spent some time this week porting the MiniSOC project to the Turbo Chameleon 64.

Hardware-wise the TC64 is very similar to the CIII board – the FPGA is identical, and there’s the same amount of SDRAM – albeit with a slightly different layout – so porting projects from one to the other is fairly straightforward.  The only complicated part is routing certain signals through a CPLD which is used in the TC64 to multiplex some of the IOs, and as a bonus, to provide 5v tolerance.  This is taken care of in the Chameleon-specific toplevel, meaning once again that the same basic source tree can be built for DE1, the CIII board and now also the Turbo Chameleon 64.

The Minimig core in action

I needed a bit of a break from wrestling with timing constraints and trying to figure out how to make the core stable from build to build, so figured I’d make a video of the Minimig core in action.  This is the first time I’ve used this particular camcorder, so forgive the shaky camerawork!
