15.6.1 Kinetis family
15.6.1.1 Unlocking
If your device has been locked by setting the MCU security status to "secure", and
mass erase via debug interface is not disabled, J-Link is able to unlock your Kinetis
K40/K60 device. The device can be unlocked by using the "unlock" command in J-
Link Commander.
For more information regarding the MCU security status of the Kinetis devices, please
refer to the user manual of your device.
15.6.1.2 Tracing
The first silicon of the Kinetis devices did not match the data setup and hold times
which are necessary for ETM-Trace. On these devices, a low drive strength should be
configured for the trace clock pin in order to match the timing requirements.
