Can't connect to FRDM-KE15Z

Frotz — Thu, 31 Jan 2019 16:46:31 GMT

Hi,

I'm having trouble with my FRDM-KE15Z. After three days of nothing but smooth and easy work trying out this nifty board, today it doesn't want to connect properly. The drive appears on my Mac, the green and amber LED's come on and the red LED flickers during the resets, but no downloading. Opening a terminal to the board works and the amber LED flashes when I type, but there's no program in the MCU to do anything as it has been erased by this point in the process. My LPCXpresso845MAX, which also arrived on Monday works perfectly, though. (FYI: I'm using one board at a time.) I've pasted in the logs below. Could you help, please?

Thank you very much,

Andre.

Hi Andre,

I guess your chip is locked. Please read this document for detail.

Ah Ha!

Thanks, Jing. You've diagnosed it right-on. It was locked. I found a super 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!

Best,

Andre.

p.s. Thanks, NXP! This setup you have is the best I've ever seen on Macintosh for such embedded development!
