Hi Jacky Ortega,

[quote user="Jacky Ortega"]Thank you very much. west zap-generate worked perfectly when using from $HOME/light_bulb i.e project directory.[/quote]

Great to see!

[1] Approach 1: Does not work:

~/ncs/v2.7.0/modules/lib/matter/scripts/tools/zap/run_zaptool.sh $HOME/light_bulb/src/light_bulb.zap

~/ncs/v2.7.0/modules/lib/matter/scripts/tools/zap/generate.py $HOME/light_bulb/src/light_bulb.zap

[2] Approach 2: Does not seems to work:

When in $HOME/light_bulb directory and using directly 'zap' command the tool opens from
/home/user/ncs/v2.7.0/modules/lib/matter/zap/zap-linux-x64/zap

[/quote]

The zap command method is outdated and were replaced by the west commands. The west commands ensures that the correct instance of the ZAP tool is called. They were introduced in nRF Connect SDK v2.7.0 to simplify the process for editing ZAP-files and generating data model files.

Best regards,

Maria

HI Maria Gilje ,

Thank you very much. west zap-generate worked perfectly when using from $HOME/light_bulb i.e project directory.

ZAP gets downloaded and executed from the following directory:
ZAP installation directory: /home/user/ncs/v2.7.0/modules/lib/matter/.zap-install

I have few questions related to several zap executable present in various directories and there use cases.

[1] Approach 1: Does not work:

~/ncs/v2.7.0/modules/lib/matter/scripts/tools/zap/run_zaptool.sh $HOME/light_bulb/src/light_bulb.zap

~/ncs/v2.7.0/modules/lib/matter/scripts/tools/zap/generate.py $HOME/light_bulb/src/light_bulb.zap

[2] Approach 2: Does not seems to work:

When in $HOME/light_bulb directory and using directly 'zap' command the tool opens from
/home/user/ncs/v2.7.0/modules/lib/matter/zap/zap-linux-x64/zap

[3] Approach 3: Works perfectly

ZAP installation directory: /home/user/ncs/v2.7.0/modules/lib/matter/.zap-install

Using the following works perfectly:

west zap-gui - For creating & editing the zap files.

west zap-generate - For Generating the respective files.

Best Regards,

Jacky Ortega

Hello,

You need to run west zap-generate after you edit the .zap file. You can do this from the ZAP tool or from a terminal as shown in the link.

Best regards,

Hi Hieu

OS = Ubuntu 20.04
VsCode = 1.94
nRF-Connect Plugin + SDK v2.7

The default matter-light-bulb samples without adding endpoint-3(MA-ONOFF Light) builds and compiles on my system but as soon as I add endpoint-3 the error messages appear.

Please see my attached zap-file google-drive link. There I have attached both '.zap' and '.matter' files. Thank you.

Hi Jacky Ortega,

I didn't encounter any such issue building the light_bulb sample. Here is my environment:

Windows 10
NCS v2.7.0
Toolchain v2.7.0
Sample: C:\ncs\v2.7.0\nrf\samples\matter\light_bulb (light_bulb)
nRF Connect for VS Code v2024.11.75
Built in-tree and out-of-tree
Build target nrf5340dk/nrf5340/cpuapp
Built with sysbuild

The only difference is that I haven't changed the .zap file from the template one. However, that shouldn't cause the issue you wrote about.

Could you provide some more details on how you built the sample? Where you put the application directory and OS version, for starter. Also, does it work if you build in-tree?

To rule out long path issues, please also try with a shorter build directory name. I understand that this issue is more common on Windows, and you seem to be using Linux, but it doesn't hurt to rule it out first.

Hieu
