Best way to debug on Kinetis tower module?

mittymcdoogle — Fri, 19 Jun 2015 14:43:58 GMT

I am trying to debug on my Kinetis tower module without much success. My module currently shows up as an mbed Serial Port device so I am debugging with an OpenOCD configuration. Whenever I do, I receive the following error message:

Error in final launch sequence

Failed to execute MI command:

-target-select remote localhost:3333

Error message from debugger back end:

Remote communication error. Target disconnected.: No error.

Failed to execute MI command:

-target-select remote localhost:3333

Error message from debugger back end:

Remote communication error. Target disconnected.: No error.

I've tried debugging with P&E/Segger and both time out.

How do I fix this problem?

Thanks,

Mitty

Hi Mitty,

I just tried this on my FRDM-K64F Freedom board that has MBED firmware so I would use the OpenOCD configuration as well.

The first time I downloaded I got the same error you had.

I then disconnected the debugger USB cable and then re-connected it. Re-tried the download and it worked.

Here are my Debug Configuration settings:

Thanks, David. I checked and I have all of the same settings, but I am still unable to debug.

Here is what my console is displaying every time I try to debug:

Hi Mitty,

Can you try to clear all breakpoints and watchpoints?

Hi David,

There are no breakpoints or watchpoints.

Thanks,

Hi Mitty,

Are you connecting the USB cable to FRDM-k64F, wait 10 seconds, disconnect and quickly re-connect the USB?

I have found that initial USB connection will not work but after re-connecting the interface works.

Secondly, attached is ZIP with MBED and PEMicro firmware that works on my board so maybe switching back and forth will grease the wheels so to speak.

Have a look at this very good blogger's report on antivirus software that might affect things.

FRDM Board not responding? Check your Virus Scanner! | MCU on Eclipse

Segger JLink firmware for frdm-k64f at bottom of web page: SEGGER - The Embedded Experts - OpenSDA / OpenSDA V2

Have you done online update of KDS by doing the Help->Install New Software... then in Wizaard select from pull-down the "Freescale KDS Update Site - http://freescale.com/lgfiles/updates/Eclipse/KDS" and Select All, Next, Finish...?

David

Hi David,

Yes, I have tried that. Also, (just for clarification) I am trying to debug a kinetis tower module, not a freedom board. I also have a freedom board that I am able to debug.

I am currently updated to KDS 3.0.0.

Thanks,

Mitty

I loaded Segger firmware (SEGGER - The Embedded Experts - OpenSDA / OpenSDA V2) and am now able to debug.

If you want to use OpenSDA in CMSIS-DAP mode there is an additional step needed that is not yet well documented.

The FRDM-K64F needs this step - all other Freedom boards I have tested (so far) do not need this extra step. They can use the standard CMSIS-DAP app (is an S19 file that we use).

We are working on a Keil KnowledgeBase article for the FRDM K64F. Here is part of it:

*************************************************************************************************

Installing the CMSIS-DAP Driver for mbed

The CMSIS-DAP Debugger in µVision needs the CMSIS-DAP driver for mbed installed on your PC to communicate to your CMSIS-DAP target board.

To install the CMSIS-DAP driver for mbed:

Download the CMSIS-DAP driver for mbed (mbedWinSerial_16466.exe) from the mbed site.
Make sure your target board is connected to your PC and has the CMSIS-DAP app installed in your target board. (installed using RESET/powerup sequence)
Install the CMSIS-DAP driver. After installation, in Windows, opening the Devices and Printers dialog should show the following new devices on your PC:
- MBED microcontroller USB Device
- MBED CMSIS-DAP
- mbed Serial Port(COMnn) nn = the COM port number

*************************************************************************************************

This is using Keil uVision but we suspect this is applicable for other tools vendors.

I am interested in hearing about any other experiences getting CMSIS-DAP working and other information we can use in our forthcoming article.
