Hej,

Currently I am trying to figure out how to setup the debugger by the use of west. I manage to start the west debug server but I failed to connect.

Maybe I am missing something or anyone having the same problem.

My steps & workflow:

"setup zephyr"

1.) open terminal

2.) set environment by "source zephyr-env.sh"

3.) build my project

4.) run "west debugserver" from my build dir

"""


"""

"setup ide"

5.) open eclipse without setting the environment

6.) create a new debug config

6.1) set in Debugger tab:

6.1.1) Debugger >> gdbserver

6.1.2) Main >> "gdb Debugger": = /opt/zephyr-sdk/sysroots/x86_64-pokysdk-linux/usr/bin/arm-zephyr-eabi/arm-zephyr-eabi-gdb
6.1.3) Connection >> "host name" = localhost
6.1.4) Connection >> "port" = 6666


Eclipse fails to connect with:

"""

Error in final launch sequence:

Failed to execute MI command:
-target-select extended-remote localhost:6666
Error message from debugger back end:

The west console print:

Any ideas how to get the combination of west & eclipse for dbg done?


There is a nice document describing the first steps with west.
