programming FRDMKL03 using SWD

[syed_idris]

Hi,

FRDM-KL03 programming using openSDA working fine.

Is it possible to program the FRDM-KL03 by using SWD connector ? How ?

Do we need to cut any trace on board to disconnect the KL03 form openSDA ?

Hi Syed_Idris,

Please review following blog:

We don't want to program FRDM-KL03 with another FRDM-KL03.

We have USB Multilink Universal FX and want to program FRDM-KL03 with this.

What changes do we have to make on board and in KDS IDE? (Cut J6 trace)

How to know that the board is getting power from Multilink Universal FX, because power LED is connected to the openSDA?

Hi Syed,

Cutting the J6 trace is not needed if you want to debug the MCU using the SWD connector, it is only needed when you want to debug another board using the OpenSDA. Regarding the changes in KDS, you will only have to update the properties of your connection to change the interface to USB Multilink instead of OpenSDA:

The board will get power from the Multilink if you enabled the "Provide power to target" option and placed the corresponding jumper in the Multilink:

Please take a look to the following post created by a colleague that shows how to debug a FRDM-KL25Z board through the SWD connector:

Hope it helps!
