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.

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

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
