B.1
IF...
Error Message (when starting the
STVD7 for DVP):
“Connection Error (LPT1):
Interconnection failure. Verify your
input/output cable.”
Error Message (during STVD7
session):
“Emulator power off has been
detected.”
ISP does not work.
Identifying the Problem
THEN...
Ensure that:
•
•
•
•
If none of the above items has been overlooked, this may
mean that your parallel port connection needs to be
reconfigured.
Please refer to
Ensure that your development board is powered on and
shutdown and restart your STVD7 session.
Certain application board configurations may prevent
you from being able to program your target MCU using
ISP mode.
Ensure that:
•
•
If you still cannot get ISP to work using your DVP, consult
the application note AN1363/0401 entitled Workaround
to ISP Mode Limitation on the ST7MDT1-DVP2 and
ST7MDT2-DVP2 which can be found on ST’s website at:
This application note describes how to download and
perform a software and hardware patch that will permit
you to use ISP programming even when you have high
capacitance on the RESET pin of your target device.
The parallel cable is connected between the
development board 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 development board is not recommended.
The development board is powered on.
The parallel cable used is the one supplied with the kit
by STMicroelectronics.
STVD7 and Windows Epromer are not running at the
same time. If this is the case then shut down both and
ensure that only one or the other is running at any one
time.
The target MCU mounted on your application board
has a power supply of 5 V.
There is low capacitance on the MCU’s RESET pin.
