Jam Player

Hello:

I'm trying to configure a cyclone using the JTAG interface driven from another cyclone devices io ports using the Jam Byte Code.

I've read and converted the jam player code (ap note AN111). I've downloaded the jbc file (binary image) into my main system.

I'm running the jbc code on a NIOS II and all seems to go well till I execute jbi_uncompress(...).

I get the status that no data was uncompressed ie data_length = 0.

Anybody got this working?

Any suggestions?

THanks

George
