X-checker Pod : Problem w/ X-checker and Win2000

Started by Vadim Vaynerman January 20, 2005
Hi all,

I have a legacy design for an XC4000 that I'm trying to program through the X-checker pod, and this has not worked under Windows 2000 or XP. Windows 98 works fine. What can I do to get this to work under the new OS?

Thanks,

Vadim

I'm not familiar with the X-checker pod, but have you tried running the program as administrator? The reason I ask is because the main difference between windows 98 and 2000/XP is that windows 98 is built on top of a DOS core, whereas 2000/XP are based on an NT core. AFAIU, the result of this is that in windows XP/2000 you can have permissions problems with the serial/parallel ports - I have hit a similar problem before, trying to program COP8 microcontrollers. (I'm assuming that the X-checker cable is something that plugs into a serial or parallel port - you could also check that no other program is trying to use the port at the same time if this is the case) To confirm whether it is purely a software issue, I guess you could put a 'scope on the outputs and confirm whether or not there's any signals going through.

Yes, it would seem to be a software issue, as nothing goes over the serial port. I have tried a utility such as userport, which allows the old inb/outb commands in Win2000, but to no avail. I was indeed logged inn as an administrator... I was really hoping that Xilinx put something out that corrected this, but it seems that Xchecker is meant to wither and die away.

Vadim, The xchecker was officially obsoleted in 1999. None have been produced since and software support was removed from all applications released after that time. The application that last used it (JTAGProgrammer and HardwareDebugger) were developed and verified to support only Win95/98 and WinNT. Changes to the Win2K and WinXP may be interfering with serial port communications. You could try and run JTAGProgrammer through the compatibility wizard and see if that makes any difference (I suspect not) I am afraid that your choices are limited to (a) not upgrading your OS -or- (b) purchasing a new parallel cable (about $150) and using the latest iMPACT Configuration Software (available as a free download) - which can still accept older bitstreams
