How many breakpoints can I set on the FRDM-KL26Z board?

[Jiun_Yong]

I am using the FRDM-KL26Z board, with Kinetis MKL26Z128 processor and OpenSDA debugging interface.

Is there a limit to how many breakpoints or watch points I can set?

Just curious as I am in the throws of debugging an annoying timing issue in my application.

No worries.

Hi Steve,

Alice has most accurate answer.

The rule of thumb is the Kinetis L devices have 2 hardware breakpoints and Kinetis K have 4.

You can also instrument the code with following:

#if 1

//DES 1=test of adding breakpoint into code, 0=default code

    __ASM(" bkpt #4");

#endif

Regards,

David
