Hello.

It is very difficult to say what may be wrong based on just the screen shots you have provided.

I have no idea what your program does and whether it is correct, when it comes to operation under Windows. Note that XP has memory protection and you can't just use pointer dereference to access physical memory range, you need to use some driver abstraction to access the card. How it's done on Windows, I have no idea, I have never programmed under Windows. The displayed error is very generic and may mean anything.

Also, this card was never tested in a PC computer, so I have no idea if there's any problem with the design that would prevent it from working on Windows.

Which revision did you use? Only revision 2.1 was production-grade.

I would also suggest to check for any manufacturing problems (bad connection, faulty ICs, solder joints etc.).

Btw. if you're using the program from test directory in source tree, it will not work under Windows. It's not a hardware problem - the program would have to be rewritten for Windows. This program can only work on operating systems that do not have memory protection.
