information about how to contact our support.

Troubleshooting

11.12.1.1
Typical problems
Target system has no power
Meaning:
J-Link could not measure the target (flash) reference voltage on pin 1 of its connector.
Remedy:
The target interface of J-Link works with level shifters to be as flexible as possible. There-
fore, the reference I/O voltage the flash is working with also needs to be connected 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.
