Hi,
I've did some programming on the FRDM-KW36 board. It wasn't really going as planned... Flashing worked fine though. I tried to upload a hello world example sketch to verify that the board was working. I got a error message with the workspace directory so I temporary made a new workspace2 directory, build the example and tried to program but I got a error message... This has been there and I can't do anything now....
Console log:

Kind regards,
having the same problem.I am trying to flah a custom board through a frdm-kw36 board with no success.any ideas?
I found the problem was that the MCU was locked, It's a simple way of unlocking a MCU in MCUXpresso that I thought I'd share with other novices so they can get going again easily:
Step 1: Open the GUI Flash tool
Step 2: Choose Resurrect locked...
Step 3: Hit Run.
In a moment the MCU will be unlocked and ready for more programming action!
Hi,
Tried it but didn't work...
I installed the J-link firmware and everything worked. It gave a message about some security readout function 0x400 I think. I could overwrite this and I re-flashed the DAP firmware and it worked... So there was some protection enabled.
So if anyone experieces these problems maybe this will help ;-)
Hello,
Maybe next time you can try to use the command "unlock kinetis" in the J-link commander to check if that works for you.

Hello,
Just to confirm, you are using the MCUXpresso, is that correct? Also, I believe you are using the MCUXpresso version 1.3, is that correct?
If you are, could you please try downgrading a version of the tool?
Regards,
Estephania
