OK, I have found out why my project wont download.
Simple project with:
CPU
OnchipMem
JTAG UART
Works fine. :)
Product Project with:
CPU
Onchipmem
JTAG
Tristate Bridge / FLASH & SDRAM
DM9000 Network interface
UARTS x9
IO
Watchdog etc.
No Worky :(
If I remove the Tristate bridge, the project works fine! Even in SOPC 7.1 with SP1 to get rid of the huge 'Java error' problem it fails to download.
I have also noticed a bug with the Tristate bridge wizard - about 50% of the time the initial screen which asks you if you want a registered or non registered interface will not render the Registered button, so the only option you see is Not registered.
So I can only guess my problem is with the new tristate bridge. Sadly I need to get a product out ASAP which needs it so I have been advised by my FAE to roll back to 7.0

Hi Tom,
I just saw your new post, there is a software patch for a tri-state bridge bug in SOPC builder. You should download the patch to give it a try.
See my post in this topic:
