11.12 Support
The following chapter provides advises on troubleshooting for possible typical
problems and information about how to contact our support.
11.12.1 Troubleshooting
11.12.1.1Typical problems
Target system has no power
Meaning:
J-Link could not measure the target (flash) reference voltage on pin 1 of its connec-
tor.
Remedy:
The target interface of J-Link works with level shifters to be as flexible as possible.
Therefore, the reference I/O voltage the flash is working with also needs to be con-
nected to pin 1 of the J-Link connector.
Programming / Erasing failed
Meaning:
The SPI communication speed may be too high for the given signal quality.
Remedy:
Try again with a slower speed. If it still fails, check the quality of the SPI signals.
Failed to verify Flash ID
Meaning:
J-Link could not verify the ID of the connected flash.
Remedy:
Check the Flash ID entered in the flash parameters dialog, for correctness.
11.12.2 Contacting support
If you experience a J-Flash SPI related problem and advice given in the sections
above does not help you to solve it, you may contact our support. In this case, please
provide us with the following information:
• A detailed description of the problem.
• The relevant log file and project file. In order to generate an expressive log file,
set the log level to "All messages" (see section Global Settings on page 309 for
information about changing the log level in J-Flash SPI).
• The relevant data file as a .hex or .mot file (if possible).
• The processor and flash types used.
Once we received this information we will try our best to solve the problem for you.
