FRDM-KW36 - unable to debug

adrian_chmiel — Fri, 08 May 2020 11:55:20 GMT

Hi,

I would like to start working with FRDM-KW36, but unfortunately I got stuck at the beginning ...

When I click "Debug" button, MCUExpressois showing me an error like in attachment.

I use version v11.1.1_3241, I checked firewall, I tried to remove *.launch in project workspace but still without success.

I reflash OpenSDA according to the link:

OpenSDA Serial and Debug Adapter | NXP

But it doesn;t work still.

In err2.png (in attachment) you can see the error from the console in MCUExpresso.

Hi Adrian

Could you please try the following steps?:

Connect your FRDM-KW36 to your personal computer.
Open the app J-Link Commander V6.62d
Make sure the connection with the J-Link was successful. You should be able to see the next message in the command line to confirm the connection.
Use the command connect.
The console will request to specify the device. Type ? in the console and press enter.
The window Target device settings will open. Select the device, in this case MKW36Z512xxx4. Make sure to pick the option that hasn't the message (allow security).
The console will request to specify the target interface. Type S in the console and press enter to select SWD.
The console will request to specify the target interface speed. Press enter to use the default speed.
If the app identifies the core of the board, the console will display:
Use the command unlock kinetis. You should be able to see a message confirming the unlock of the device.

If you have any problem with this process, or if you need more information, please let me know.

Now is better, but....

MCUxpresso can detect the board via J-Link, I can erase memory, program new software, but debugging doesn't work.

When I try debug:

Hi Adrian

Could you please check if you have the latest OpenSDA version (v2.2) in your board?

If you don't, could you please try downloading and programming it to your board? You can find it in this link. Please, follow the instructions in the page. Also, could you please make sure that your drivers are updated? The links for the Segger and CMSIS-DAP drivers are in the page.

If you have any problem with this process, or if you need more information, please let me know.

If I understand correctly, I can choose whether to upload Segger or DAPLink?

When DAPLink 2.2V is programed:

Drivers are installed

And the red LED on the board lights up

When Seger is programed (last wersion form 2019-06-03 and driver 6.72c), then I can read and program board.

But when I click Debug (blue one)

Drivers are installed

The red LED on the board is no longer lit.

Of course I can develop program like that, but without a debugger it is completely uncomfortable...

I know this link, but unfortunately it looks different for me and there is no this checkpoint to mark.

I think is a GDB issue

I have installed python 2.7 with included python path in system enviroment. (python 3.x is not installed)

There is also a Python path in the project preferences.

Manual connection via GDB works, the problem only occurs in MCUXpresso.

And in this way I found a bugg, JLink server is not started by MCUXpresso in debug mode.
When SEGGER J-Link GDB Server is running manually as a separate program, then debugging is works fine in MCUXpresso.

Could you check and verify it in the next release of MCUXpresso?
