Matter and OpenThread Memory Requirements

[donghyuk]

Hello,

I have a question regarding the Matter Memory Requirements referenced in the links below:

1. https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/getting_started/hw_requirements.html
2. https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/thread/overview/ot_memory.html#id12

Regarding URL 1), should I interpret the Memory Requirements as referring to the Matter Application only?

Specifically, since running Matter over Thread requires the OpenThread + BLE Stack, I am wondering if the OpenThread ROM/RAM usage listed in URL 2) needs to be calculated separately.

Is it correct to assume that the Matter Application ROM/RAM (from URL 1) consumes the "Free ROM" and "Free RAM" described in URL 2)?

Thank you.

Hi,

 

Regarding URL 1), should I interpret the Memory Requirements as referring to the Matter Application only?

This ROM/RAM number includes any dependencies, such as OpenThread configuration it uses.

Ie. it is the fully compiled application for each configuration (release or debug).

 

Kind regards,

Håkon
