I don't know much about programming flash yet so I don't have any ideas. I have looked at the documentation for the UC3F FLASH module, and it is different from the way the AMD part works in that it is register based. I may try to sort out how the flash stuff works and add support for it. If you want to send me a few ideas for cleaning things up I'll look at them. Patches will come in about a week, I have to finish a first version of this project then I'll clean things up and check that it builds on Linux. I'm not sure I'll be able to test it, though, since I don't have a local Linux box. Peter Peter Dufault HD Associates, Inc. |
