OpenSDA port error when IDE debugging

hedj — Mon, 14 Oct 2019 06:39:20 GMT

When I tried to debug my app using MCUXpresso IDE, I have this error.

My board is MK22FN512VLH12.

In my device manager, I can see a "OpenSDA CDC serial port".

Can anyone tell me what went wrong?

Some older Kinetis boards ship appear to ship with OpenSDA firmware supporting P&E VCOM but with no actual debug support. I suspect that this is what you have.

To update this firmware, please visit the OpenSDA Firmware Update pages linked to within the IDE menu:

Help -> Additional Resources -> OpenSDA Firmware Updates

My IDE (v11.0.1 [Build 2563] [2019-09-01]) shows me the above choices.

By clicking "OpenSDA probe firmware", I was redirected to a web page "OpenSDA Serial and Debug Adapter | NXP ". But I cannot find my board in the drop down list.

Hi,

K22 please use TWR-K22F120 or FRDM-K22F.

Now when I connect the board to my computer through USB, what I get is a "maintenance" drive; however I don't get COM port; and I still cannot debug with MCUxpresso.

In the drive, there are two files: details.txt and help_faq.html.

the content of details.txt is as follows:

How can I get the serial port to work??

If the board shows up with 'maintenance', it is in bootloader mode. This means you have not loaded the debug (Segger, P&E or CMSIS-DAP) firmware to it?

In order to debug the board and to have a VCOM, you need a debug firmware loaded.

See Illustrated Step-by-Step Instructions: Updating the Freescale Freedom Board Firmware | MCU on Eclipse if you are not familiar with the process.

I hope this helps,

Erich

I managed to get a JLink CDD UART port by copying Jlink_OpenSDA_V2_1.bin into the maintenance drive; after that the drive name becomes FRDM-k22FJ. I want to use MCUXpresso to flash my app firmware into the board, please suggest what I should do.

Many thanks.

I use MCUXpresso to launch J-Link Segger GDB server; however there is connection error:

Error in final launch sequence:

Failed to execute MI command:
-target-select remote localhost:2331

Error message from debugger back end:
localhost:2331: No connection could be made because the target machine actively refused it.

Hi,

You can download a jlink tool (JLink_Windows_Vxxx.exe) from https://www.segger.com/downloads/jlink/JLink_Windows.exe

It is the driver and tool that can test and control jlink interface.

I downloaded and tried to use the J-Link app to connect to the board, got similar error.

Hi,

In j-link commander, please try "unlock kinetis".

If it can't work, please try "connect". Then follow it step by step.

when I run J-Link command, I was prompted with this:

what is the IP address I shall put in?

I also ran into this:

Is there something wrong with my board?

Mk22 (and any other Cortex-M device) does not support JTAG. You must use SWD instead.

Re: OpenSDA port error when IDE debugging

hedj — Tue, 29 Oct 2019 08:58:20 GMT

SWD also failed

Hi,

This is maybe a hardware issue or the chip is locked. Please refer to below link

Communication error while accessing MDM-AP.

If everything fails - the soldering iron is only option.
