Hi ag1998,
If you use the customer board, you can use the SWD10 pin to program your customer board chip target.
What's the debugger you want to use? FRDM board as the debugger?
If yes, you just need to disconnect the FRDM on board debugger, then connect your FRDM SWD interface to your own customer board SWD pin, and power on your customer board is OK.
About the SWD interface, you can refer to the FRDM board, take FRDM MKL26z as an example:
Disconnect J8, then connect J7 to your own customer board SWD 10 pin port.
Please note, the SWD 10pin is the same as J7 on your customer board.
pin1: VDD 3.3V
pin2: SWD_DIO, which need the external 10K pull up resistor
pin3, pin5: GND
pin4:SWD_CLK
pin10:reset pin, this pin in the MCU chip side, need to add 4.7 to 10K pull up resistor, and 0.1uf capacitor to ground.
Except these, NMI pin also need to add external 4.7K to 10K pull up resistor.
Then you can firmware your FRDM-KL26 as the JLINK firmware, which can be downloaded from this link:

Wish it helps you!
If you still have questions about it, please kindly let me know!
Best Regards,
