Can not debug MIMXRT1050-EVK via J-Link

ryanshuttlewort · ‎12-11-2017

Hello I am using MCUXpresso IDE, version v10.1.0 [Build 589] [2017-11-14] with an MIMXRT1050-EVK SDK, version 2.3.0 (2017-11-16). I am attempting to download and debug the hello_world_xip example via a Segger J-Link Plus but I am running into the following error:

I have reviewed the IDE user manual and other posts in other NXP forums which appear to be very similar but the suggestions have had little no no effect. i.e. 890826, 447820, 891538

Once the error has occurred, it will occur instantly with each new debug attempt and I can not attempt the connection process again without a reboot of the IDE.

The j-link console shows what appears to be a successful connection to the processor followed by a sudden "Server has been shut down." message. I see no obvious errors in the the GDB and JLinkServer output.

Here is my J-link setup:

The "Source" and "Common" tabs are in their default state.

Any insight into the j-link error would be appreciated, thanks.

Fixed, you have to right-click on prroject -> Launch Configurations -> Create New -> Segger J-Link Probes (or what ever your new probe is). All subsequent debug attempts will use that config. until changed again.

Do not attempt to create launch configurations manually, this just leads to unusual issues.

Hi Ryan,

If a project has no launch configuration i.e. because it has just been created, then on the first debug attempt, a debug probe discovery will be performed - this by default will look for LinkServer, P&E and SEGGER probes. Once a probe is chosen and used, a launch configuration for that probe type will be created automatically and associated with the project.

Once a project has a launch configuration (LinkServer, P&E or SEGGER), a subsequent debug operation will be restricted to the probe type matching the launch configuration (primarily for performance reasons). However this behaviour can be overridden by holding down <SHIFT> and clicking Debug from the Quickstart pane. Note: the existing launch configuration will only be replaced if the debug operation is actually started.

The MCUXpresso IDE User guide discusses this behaviour in the Debug Solutions Overview section.

Yours,

MCUXpresso Support

Yes, I found the issue as mentioned in my last post and marked it as answered at that time. Thanks.

An update on the original issue. There appears to be a bug or "feature" in the IDE such that if J-Link is not present on the very first debug attempt (blue bug button press) you will never be given the opportunity to add j-link again during the probe discovery process on subsequent debug sessions. The following images demonstrate this.

This is the menu I see on a project where J-Link was not used on the very first debug, as you can see there is no J-Link or P&E Micro probe search options, only CMSIS-DAP probes even though a J-Link probe is present on the system:

The above menu options appear even though auto-discovery of other probes seems to be enabled:

Now, if the project is completely deleted and re-imported but this time with a j-link probe attached I get the following screen:

However, once J-Link is selected I never again get an option to use other probes like CMSIS-DAP even though one is attached:

This behavior seems to be present on OSX and Linux.

Any ideas how I can get around this without deleting an existing project?
