kinetis security fails

okaner — Mon, 06 Oct 2014 18:15:27 GMT

Hi all,

I am trying to secure kinetis k10 microcontroller. Normally my project works without any problem. If I enable the security option from processor expert, my code does not work. The only thing that I do is enableing the security checkbox below. Probably my code does not start. Any suggestion please...

Okan,

Hi Okan,

what are you using for downloading it to the target? E.g. if you use Segger, make sure you use the device with (allow security) listed.

Hi Erich,

I use PE Micro multilink. You can find the programmer logs below. I realized that at the bottom of log it is written that "Device is secured. Erasing ...". It says "Erasing" at the end, is it normal.

Yes, this is normal, if you have secured the device before.

Do you have any suggestion to try. Next monday I will give my products to customers :smileyhappy: I dont want to give them without security.

Dear Erich,

I made a new just LED blinking project. Normally it works fine. After securing, it does not blink. I really dont know why.

Hi Okan,

I've found an interesting post on community which can may be help you.

Re: K10 custom board

This post refers to 2 ANs:

How (not) to Secure my Microcontroller | MCU on Eclipse

Device is secure? | MCU on Eclipse

Hope this will help.

Have a great day,

Dear Pascal,

Thank you for your reply. Actually I dont have problem with programming my board. If I program my board with unsecure device settings, I have no problem and my board works well. If I choose to secure mcu from processor expert and program my device, my board does not work. I made a simple LED blinking project to test it. You can see the source code at previous image. I tested at different boards, same result. Thank you again.

Okan,

Hello Okan,

Are you trying to program or to debug it?

If you just program the board (You can try with Flash file to target in CodeWarrior, the blue thunder icon) it should work.

Regards,

Santiago

Dar Santiago,

Thank you very much for your answer. Actually I was not debugging but using "run as" to program the mcu. Programming with thunder icon worked.

Okan,
