TREL enabling failed in NCS 1.3 Build

[shouvik-grl]

We are trying to make a NCS build with the TREL functionality.

For that we added the TREL flag CONFIG_OPENTHREAD_RADIO_LINK_TREL_ENABLE=y in the config/ncs/overlay-cli-1_3.conf and config/ncs/overlay-rcp-1_3.conf files

During the 1.3 build we are getting error (Error log attached). TRELBuildErrorLog.zip

The command for the build we are using is: REFERENCE_PLATFORM=ncs REFERENCE_RELEASE_TYPE=1.3 IN_CHINA=0 ./script/make-reference-release.bash

@shouvik-grl if You remove CONFIG_OPENTHREAD_RADIO_LINK_TREL_ENABLE=y from config/ncs/overlay-cli-1_3.conf the configs should be fine.

@canisLupus1313 After removing CONFIG_OPENTHREAD_RADIO_LINK_TREL_ENABLE=y from config/ncs/overlay-cli-1_3.conf . we are getting a new error, attaching the error log with this.

@sam-grl do You mean this warning?

/OTBR_Images/ShouvikTry/TRELBuild/ot-reference-release/ncs/zephyr/modules/openthread/platform/./openthread-core-zephyr-config.h:292: warning: "OPENTHREAD_CONFIG_RADIO_LINK_TREL_ENABLE" redefined
  292 | #define OPENTHREAD_CONFIG_RADIO_LINK_TREL_ENABLE

Because I can see that both CLI and RCP samples building process was successful.

[shouvik-grl]

@canisLupus1313 OTBR image (Pi image) building process was unsuccessful. We tried 3 times and every time got same issue.

@shouvik-grl This looks like problems with internet connectivity.

On my site those are downloaded without a problem can You verify that you are able to update raspbian? Maybe you some proxy or firewall issues?

@canisLupus1313 Thanks for your support

We changed the mirror server from India to Oxford server and after that the, build was successful. [TREL Flag is ON]

But TREL related commands are not working.

I can see a new PR, Is it related to TREL also?

[canisLupus1313]

@shouvik-grl can you try to dirty hack and in file ot-br-posix/third_party/openthread/CMakeLists.txt change line

set(OT_TREL ${OTBR_TREL} CACHE BOOL "enable TREL" FORCE)

to

set(OT_TREL ON CACHE BOOL "enable TREL" FORCE)

[sunytt]

To get TREL enabled you could also try to update the OTBR_OPTIONS, by changing -DOT_TREL=ON to -DOTBR_TREL=ON @shouvik-grl

[sam-grl]

@canisLupus1313 and @sunytt Thanks for your suggestions, These changes worked Perfectly.
