FRDM-K64F "blocked" and I can't program it anymore.

Hello, good day.

I was doing some test with a simple code to turn the LEDs on in a certain color sequence (I had tested the code before and it worked fine). But, suddenly the K&4disconnected  and it kind of "blocked" itself, now I am unable to load any code into the K64. I get the following error:

I tried to check the K64 with J-Link Commander and also I an error, it is the following one:

Also, I noticed that the K64 starts to warm up when I try to load code.

Can you please help with this? I don't really know why this started to happen.

Best regards

>Also, I noticed that the K64 starts to warm up when I try to load code.

That is indicating to me that you have a hardware failure and the K64 is damaged (ESD maybe?).

Is this your custom board or the FRDM-K64F?

I'm affraid that you would have to change/replace the MCU/Board.

I hope this helps,

Erich

Oh dear, well, thanks a lot for the quick response. Do you know if there is some warranty that I can use? I bought the K64 about 2 months ago.
