SWD in KL03

[javierhernande1]

Hello,

It's right this connection in order to program the KL03 32kb QFN-24 with the LPC_Link_v2 ?

With 3 wires, DIO, CLK and RESET because I can not put a SWD standard connector because I have not space.

[Robin_Shen · Accepted solution]

NMI_b(PTB5)     external pullup resistor
SWD_DIO(PTA2)    external pullup resistor
SWD_CLK(PTA0)    
RESET_b(PTA1)    external pullup resistor / 100 nF capacitor

GND is needed when using LPC_Link_v2 connect to KL03.

Best Regards,

Robin

Thank you!,

Then, it's ok so?

SWD_DIO

RESET

Is the capacitor well connected? It's a 100nF 0402 ceramic capacitor.

NMI

I had already NMI pull-up 10K resistor and one button in order to enter in boot mode. It's necessary the NMI pad for use the LCP_Link2? It's enought with the button? I can remove it?

SW1 the only button I have on the pcb. I plan to use it to change channels/bands and to enter boot mode.

Best regards

Hello,

I'm try to programmer the KL03 with the LPC-Link2 but I get this error (in linux):

The wiring is so to the ARM Jtag 10 pins:

MKL03 - LPC-Link2

Reset PTA1 - Pin 10 RESET  (10K 1%)

SWD_CLK PTA0 - Pin 4 TCLK

SWD_DIO PTA2 - Pin 2 TMS  (10K 1%)

GND  - Pin 3

On the board the button is connected to the PTB5 NMI (pullup with 10K 1%) of the MKL03

Have you try to configure LPC link-2 as CMSIS-DAP?

[jhd]

Yes, but I'm having problems with that.
