[reprinted] Not enough RAM retention to run sleep_enddevice in deep_sleep mode

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

Is there any way to resolve this error? Thank you!!!

Hi,

  tlsr9518adk80d's retention ram is 64K,Contact-sensor-app need 74K ram ,so tlsr9518adk80d can not run Contact-sensor-app in retention state,you can change the prj.conf change the retention to suspend mode ,also it will increase current.

or you can try tlsr9528a chip,it has 96k rention ram to support Contact-sensor-app
