I'm designing a "Bare Bones KE02Z64" board. What are the minimum signals that I need to bring to an ICSP connector in order to download programs into Flash? I have a FRDM-KL25Z development board that I can use as a programmer.

Hi craig ross ,

  You can use the SWD interface to download the code with the external debugger.

  The SWD interface is: VDD, VSS, SWD_DIO, SWD_CLK.

  Actually, you can refer to the FRDM-KE02 board:

FRDM-KE02Z40M|Freedom Development Platform|Kinetis | NXP

In your hardware, please note these points:

1. Reset_b pin need to add external 4.7k to 10K pull up resistor, and 0.1uf capacitor to ground.

2. NMI pin need to add external 4.7K to 10K pull up.

3. SWD_DIO need to add external 10K pull up resistor.

Wish it helps you!

If you still have questions about it, please kindly let me know.


Have a great day,
Kerry
