Hi everyone,

 I need help with a battery-operated device (sleepy end device) supporting the Matter-Thread standard.

 I have used:

- Connectedhomeip: branch master

- Zephyr: branch develop

- Example: Contact-sensor-app

- Build command: west build -b tlsr9518adk80d_retention


Build error:

"[644/654] Linking CXX executable zephyr/zephyr_pre0.elf
