impact:477 the bsdl for device 'UNKNOWN' is out of date
does anyone have any idea? I have this error when working with system ace. i'm trying to make my Virtex4 XtremeDSP kit to be self-programmabel using system ace. I built the system ace circuit and encountered this error. What i did was i hooked up the jtag cable to my board's 'test jtag' port, and i hooked up my 'config jtag' port to the xtremeDSP kit. I tried to initialize chain using impact and i got this error.
I tried using the system ace board with my spartan3 board and it detects all the devices with no problem, including the system ace chip. But when i tried to use it on the XtremeDSP kit, it keeps giving me error and the boundary scan in impact shows random results. sometimes it shows alot of devices detected in the chain, but they are unkown, sometimes it shows that it only detects 2 or 3 of the devices in the chain, and this happens very randomly.
can anyone suggest anything here?
thx
