Error messages

If the following error occurs:

Then...

Error 10025

Emulator initialization error

This error occurs when one of the software files needed by STVD7 in order

to initialize the emulator is missing or damaged. Check that:

●

STVD7 has been properly installed—re-install STVD7 if in doubt.

●

Any necessary firmware upgrades have been performed—see

Section 4.6 on page 23.

If this error persists, contact STMicroelectronics Product Support.

Error 20004

Communication initialization error

This error only occurs when STVD7 cannot initialize the emulator during

startup (when you click the Debug button to load your application into the

emulator).

Ensure that:

●

The parallel cable is connected between the ST Micro Connect box

and to the PC parallel port (LPT1 or LPT2) that you specified

when installing STVD7.

●

You have not placed any switch boxes between the parallel port

connector of your PC and the ST Micro Connect box.

●

The ST Micro Connect box is powered on.

●

The parallel cable used is the one supplied with the by

STMicroelectronics.

If none of the above items has been overlooked, this may mean that your

parallel port connection needs to be reconfigured. Please refer to

Section 3.1.2 on page 10.

Error 20013

Communication error

This means that the communication link between STVD7 and your emulator

has been broken while STVD7 has been in use. Check that:

●

The parallel cable is connected between the ST Micro Connect box

and one of the PC’s parallel ports (LPT1 or LPT2). Note that the use

of switch boxes between the parallel port connector of your PC and

the ST Micro Connect box is not recommended.

●

The ST Micro Connect box is powered on.
