AmebaD Evaluation board is not detected by Jlink

[LokrajPatro]

Hi,

I am using Realtek AmebaD evolution board to explore Matter protocol feature for Thermostat applications. I could build and flash the device with thermostat example application , referred the

“AN0204 Realtek Matter Application Note” to perform the same.

Now, I am trying to setup the Debug environment for the device. I am referring section 1.4 Setting Debugger section “AN0400Ameba-D Application Note” to perform the same.

The Jlink Debugger is detecting by Jlink script. However, The AmebaD device is not detected.

Setup:

Linux OS version: Ubuntu 22.04.3

Debugger: Jlink Ultra +, Version 4.5

Please help me to resolve the issue.

Please find attached snapshot of log.

Thanks,

Lokraj

@LokrajPatro what command line did you use to start the jlink gdb server?

[LokrajPatro]

I am using "/opt/SEGGER/JLink/JLinkGDBServer –device cortex-m33 -if SWD -scriptfile AP2_KM4.JLinkScript –port 2335" command to start the jlink gdb server. As mentioned in “AN0400Ameba-D Application Note” document.

Hi @LokrajPatro may I inquire about the version of JLink GDB Server you are currently using? Thank you.

@LokrajPatro could you check the connections to the board again.

[LokrajPatro]

Hi @xshuqun , I have verified the wiring connection. This is as mentioned in 1.4.2 J-Link section of the AN0400 Ameba-D Application Note.

Thanks

@LokrajPatro, could you check if the EVB (Evaluation Board) is powerup? Based of what I have tested, either the EVB is not powerup or the GND&1833 connection has been flipped.
