TWR-KM34Z75M cannot debug using J-Link

isaotakashima — Thu, 15 Mar 2018 09:39:27 GMT

I started develop the new project for MKM34Z256VLL7 using TWR-KM34Z75M and J-Link JTAG ICE.

I used MCUXpresso IDE v10.1.1 [Build 606] [2018-01-02], I believe that it is latest version.

But I have the following error, then I cannot debug using J-Link.

The Initialization Commands of Startup tab has "monitor reset" command as below.

I can debug using J-Link after remove "monitor reset" command as below.

Here is my questions.

Can we remove "monitor reset" command from Initialization Commands of Startup tab to get proper operarion?

Why the default settings of Initialization Commands of Startup tab?

Please reply as soon as possible.

Best regards,

Takashima

Dear Alice Yang,

Thank you for your reply.

I find out the below screen shot, no "monitor reset" command.

Then I can remove "monitor reset" command from window of Initialization Commands.

There is no other information, I cannot find a clear answer to my questions.

Again, I asked.

Can we remove "monitor reset" command from Initialization Commands of Startup tab to get proper operarion?

Why the default settings of Initialization Commands of Startup tab has "monitor reset"?

Please reply as soon as possible.

Best regards,

Takashima

The "monitor reset" command is included because generally it is needed for a successful connection. See SEGGER's J-Link documentation for more details of this command. But if you have found a particularly situation where removing it allows your debug connection to work, then simply remove it and resave the launch configuration. The modified version will then be used by your project for future debug sessions.

You will find more information on what is going on during a debug connection in the Console view, in particular the JLinkServer console. This may give you some clues as to what is actually happening in your setup.
