Getting there....

CoreOne revision 2 is getting there. Component placement is 99% there, just need to move 4 jumpers to remove a break in a ground connection. Other PCB revisions are almost complete as well.

I still cannot get the EEPROM working on existing DSP boards. I am at a complete loss here. They used to work on early SigmaStudio versions. I shall keep poking away at it and there is a small hardware change I can try, removing a pull-up resistor on the EEPROM chip select line. I am not sure why it would make a difference now, but might be worth a try.
