KITPF09FRDMPGM – Wrong Board Included?

d_j — Fri, 02 Oct 2026 11:10:49 GMT

I ordered a KITPF09FRDMPGM. The delivery included the KITPF09FRDMPGM and a separate FRDM-KL25Z board.

However, I don't think the two boards are compatible, or at least I don't see how they are supposed to be connected. For example, the J21 header on the FRDM-KL25Z is mechanically in the way.

In addition, the pin headers required to plug the KITPF09FRDMPGM into the FRDM-KL25Z are missing.

Could somone please confirm whether the correct board was included with the kit? Shouldn't it look similar to the board supplied with the KITPF7100FRDMPGM?

Hello,

The board included with the KITPF09FRDMPGM is the correct board. The KITPF09FRDMPGM and the FRDM-KL25Z are supplied as separate boards and are compatible when assembled as intended.

The required pin headers are not included pre-installed and must be purchased separately and soldered onto the boards. Once the appropriate headers are installed, the boards can be connected correctly.

I have tested the KITPF09FRDMPGM board without any problems, so the board itself is correct and functional.

Hope this helps!

I’m still surprised that it’s supposed to fit. The outline is different, and connector J21 interferes with the board. Should I desolder it?

Shouldn't the controller board look more like this?

Okay, I’ve thought about it again. J21 is probably just a jumper and won't interfere with the top board if the pin headers are installed. I'll give it a try.

I have now soldered on the headers. However, nothing happens when I try to connect the kit using the NXP_GUI. I also found an old kit for the PF8100 with an older FRDM-KL25Z; that one is detected. What could be wrong?

Perhaps I bricked the firmware. Can you tell me if this the correct firmware: OpenSDA/PEMicro/2016-02-08/MSD-DEBUG-FRDM-KL25Z_Pemicro_v118.SDA at master · savoca/OpenSDA · GitHub

...or can you give me the link to the correct firmware?

Hello @ErikaC,

as I am a colleague from d_j:
Can you please check his question and provide us with information, which firmware is needed for this board? We both can not establish the connection as the "start" button is inactive. We both use Win11, not Win10 as suggested by the documentation.

Thank you in advance.

Best regards,
Florian
