MKL03Z8VFG4 and J-link: unlock failed

[romanstorozhenk]

I have been using the MKL03Z8VFG4 and J-link. I had the unlocking problem that is widely reported almost every single time but this last board I believe does not want to be unlocked. J-link print: "Timeout while unlocking device". Maybe try another new chip?

Hi Roman,

Does the board work well?

I think you can have a try with the new chip instead of the old one.
Have a great day,

HI Jeremy!

Put a new chip, new chip operates.

Later I will try once again to flash the old, you need to find out why it inoperable.

Have a nice day!

Hi Roman,

I was wondering if you can share me with the sch of the mini-system design which include the power supply, reset pin, OSC, debug interface, etc.I think it can help me to figure out the cause of the issue.

I'm looking forward to your reply.
Have a great day,
