How To Program MKW21D256V with 10pin J-Link Programmer

[ultrademon666]

Hello people of the forum:

I need to program a MKW21D256V using a Segger J-Link's J-TAG and a 10-pin connector for the J-Link.

The documentation doesn't inform about the pins for TRST and RTCK signals.

Microcontrollers of the same family like the MK20DX128VLH5 uses those pins and are necessary for programming  the chip properly.

I would like to know the correct way to connect and program the MKW21D256V using the J-Link and the 10-pin connector.

Thank you.

Hello Jose:

The 10-pin connector you talk about has only 9 populated pins, right?

You can refer to the schematics of the tower board TWR-KW21D256, which is available in a package called "TWR-KW21D256_PCBRD" at the next link, under "Printed Circuit Boards and Schematics...":

KW2x: Kinetis KW2x Family of 2.4 GHz RF MCUs

The tower board actually has a 19-pin header connector, but the first 1-10 pins match those of the 9-pin connector in J-link.

Hope this helps!

Regards!
