warning: attempt to assign the value 'y' to the undefined symbol DEBUG_PORT_ACCESS

[Learner]

Hello,

I have added the line CONFIG_DEBUG_PORT_ACCESS=y in prj.conf file and now the project does not open in Segger Embedded Studio (SES).

I am getting this error,

warning: attempt to assign the value 'y' to the undefined symbol DEBUG_PORT_ACCESS
error: Aborting due to Kconfig warnings

Note, I am using nthis version of Zephyr

Zephyr OS build v2.6.99-ncs1 and SES

and this version of SES 

SEGGER Embedded Studio for ARM
Release 5.60  Build 2021081102.47262
Nordic Edition
Windows x64

It looks like I am missing a file where DEBUG_PORT_ACCESS is defined.

Please help.

Kind regards

Mohamed

I am not seeing a Kconfig symbol called DEBUG_PORT_ACCESS defined anywhere in NCS using Zephyr v2.6.99-ncs1-1

What are you trying to do that indicated it needed that configuration?  Would it maybe require a different version of Zephyr that has that configuration defined?

Hi,

Thank you for the prompt reply.

Maybe you are right I need to move to a more recent version of Zephyr.

Which version has DEBUG_PORT_ACCESS defined?

We've recently migrated from the non-secured nRF52833 SoC to the secured version and I needed to Configure access to the debug port.

Kind regards

Hi,

I created a new local Kconfig file in my project folder and added the following lines,

menu "MyDevice Settings"
config DEBUG_PORT_ACCESS
    bool "Allow access to debug port across reboots"
    default false
endmenu

menu "Zephyr Kernel"
source "$ZEPHYR_BASE/Kconfig.zephyr"
endmenu

and now I am not getting the warning/error I reported in  my original post and the project loads fine in SES. Happy days!

Kind regards

Mohamed
