Many thanks & much appreciated!

Were X2 of the -6 variant XC95288XL the final CPLD requirement in the end or did the -10s cut it?

I await the answer with some trepidation! :lol:

I've put a 10ns on the bus cpld and a 6ns on the RAMCPLD. The ram CPLD has to cope with 200Mhz in places (clock control).

Which RAM are you guys using for 128 MB?

Thanks Mark. I notice these are 143 MHz, that enough? There is also a 166 mhz version by ISSI.

The RAM is never run at more than the CPU speed so getting expensive parts isnt necessary.

Got a bunch of family things to sort out today. Cant get a firmware to boot Diagrom in the 20 mins I spent at it.

Suffering from a PnD related hangover...

Ok it boots with a hardware patch.. need to sort the reset lines in firmware then we're good.

LoL I bet your head is hurting :) but you want to hurt it some more with a sit at your lab table doing some `Burnination` coding
so fair play to yer :)

As I told you bud my TF1260 r1 is nearly `Oven Ready` !

Try this firmware "as is" .. i dont expect it will work without a hardware patch but you can try.

For some reason the clock multiplier didnt output anything for me on channel 2 (I hadnt noticed it was a current drive differential)
I've a few theories about why i wanna run down.
