Step1: delete all files in the 7188E/8000E.

Step2: download one Xserver demo program(for example, Demo4.exe) into the 7188E/8000E.

Step3: run this demo program.

If you can see the 5-digit LED shows some information repeatly and the LED light is

flashing, that means the hardware is fine.

You can download another Xserver demo program into the 7188E/800E, and run it.

If the 7188E/8000E also runs properly, that means the hardware is realy fine.

The problem maybe due to that

   (1) you wrote some code with wrong syntax.

   (2) the program want to write some data to somewhere in the memory that you shouldn't

        change it.

        For example: the memory that store MiniOS7 or your program.

   (3) the program run some function that takes more than 1.6 second. That will

        let the 7188E/8000E be reset by the hardware watchdog.

When you make the project, the compiler (for example, TC 2.01 or BC++ 3.01) will not

check these problems and show any warning.

But, when you download the program into the 7188E/8000E and run it, it

will cause the error and stop the program.

To solve (1) and (2), check your code.

To solve (3), add function "RefreshWDT();"  in your program to refresh the watchdog

before 1.6 second is up.
