jtag programing sample

[yaronlederman]

Hi,

I'm using an other arm board and to control another my K60 ARM board - and I'd like to use the controller gpio as a JTAG programmer for the K60 ARM -based MCU board

The other ARM device is : MK60FN1M0VMD12 from Freescale.

based on the ARM Cortex-M4 is based on the ARMv7

First do you see a problem in doing so ?

Secondly is there a open-source implementation that can be references to perform such a task. Or otherwise is there a recommended reading to perform such a procedure ?

Thank you

Hello Yaron Lederman:

Your requirement is possible but it is not usual and there is not much information on implementing it since there are many JTAG/SWD interface solutions already available, either commercial (e.g. P&E tools, Segger tools) or open source/open hardware (USBDM, CMSIS-DAP).

If you want to dive into the open source solutions for reference, here are some links:

USBDM: USBDM Debugger interface for Freescale RS08,HCS08,HCS12,Coldfire and ARM-Kinetis Devices.

CMSIS DAP - Handbook | mbed

An example CMSIS-DAP implementation shared by a colleague:

Is there an App Note or software available for a K60 to program a KL14/15 through the SWD interface?

Regards!
