Encountering Issues with LPCXPRESSO55S69 Debug Probe Setup

[yidaen]

hi everyone,

I just unboxed a new LPCXPRESSO55S69 board and I am planing to program it with Zephyr. While following guide, I learned that I need to install the debug probe software. To do this, I downloaded the LinkServer Debug Host Tools. Afterward, I ran the "program_JLINK" script but encountered the following error.

The J4 force DFU jumper on my board is connected, and I've tried power resetting the board multiple times. Has anyone else encountered this issue and knows a solution?

Ubuntu 24.04

Hello, my name is Pavel, and I will be supporting your case, I recommend download the last version of LinkServer.

LinkServer for Microcontrollers | NXP Semiconductors

Best regards,

Hello, thank you for your help.

I reinstalled version 24.9.75 of LinkServer, but there was no change in the output I received.

Hello, just to confirm, is the P6 USB connector used to communicate the LPC to the Host PC during the DFU? The other way, I recommend verify the all the Jumpers on the board.

Best regards,
Pavel
