I meet a problem.I never see the phenomenon that the system ID is still keeping 0x00000000.
But my Nios in the device is matched with the software.The display on the computer is
underside.I have designed a board success,but this time i have no way to solve it.

你的软件和硬件是对应的吗，一般来说这样使你用以前的硬件版本，用新的软件版本（新的软件建立在新的硬件上）。或者是新的硬件，老的软件。你看看是不是你的备份有问题。
