When programming a MKL02Z target from my newer computer using J-Link I get a "Write protection detected" warning and cannot seem to program the processor. Using the same hardware my old computer does not get that message and is able to successfully program the part. relevant information is:
1) Used J-Link Commander V6.62d on my new computer, then upgraded to V7.88h with no change: both display the write protection message when using the "connect" command.
2) When using that command, changed the speed from 4MHz to 100kHz in case it was a speed issue
3) target hardware is self powered and connection is through SWD
4) J-link Commander version on old laptop is V7.20
5) Both systems are running Windows10 OS
Screen captures attached.
Any suggestions?
Thanks!
