Error in final launch sequence

srrp — Thu, 25 Mar 2021 16:33:59 GMT

Hi,

I'm trying to build and debug an sdk example on my LPC54018. I'm using MCUXpresso IDE v11.3.0_5222 and SDK LCP54018.

I'm able to import the project, to build the project (which give me zero errors) but when I debug it, it keep showing this error.

Hello,

How about debug a simple LED SDK demo?

If still can't work, please enter ISP mode, erase all, then debug again.

About detail refer to：

I think the Eclipse debug interface is unneccessary difficult and awkward.

Have you started the debuuging properly ?

First, select the debug dropdown menu, as shown in the snapshot.

From the menu, select "Debug as...".

Then, select the proper debug adapter. In your case, probably "MCUXpresso IDE LinkServer (CMSIS-DAP)".

Hello Frank,

You can directly choose debug way refer to your debug probe under "Quickstart Panel",

or click "Debug" button and pressing Shift button on your PC, IDE will search the debug probe automatically.

If I am remembering correctly - only once you went through the mentioned process, and selected one of the available debug options. I know, this is one of the Eclipse quirks.

Other toolchains do this in a much better and and more comprehensive way. The debug pod is selected during project setup, since it is usually fixed by hardware, and rarely ever changes for a project. You just press a "debug" button, and the initially assigned adapter is assumed. E.g. with IAR WB, Keil uVision, and Rowley Crossworks.

There is a preference (Window->Preferences) to select which probes to 'discover'. If you don't have (for example) a J-Link or a P&E probe, just uncheck them from the list - see screenshot below

Next time you start a debug session with a new project, it will only look for those that are checked.

Note that once a debug probe is selected for a Debug configuration, the probe persists, so it is a one-time selection.
