EFR32 4180B Support #8743

Closed kai0989 closed 2 years ago

kai0989 commented 3 years ago

Problem

As described on Silicon Labs website https://www.silabs.com/development-tools/wireless/slwrb4180a-efr32xg21-wireless-gecko-radio-board the 4180A-board is obsolet. The successor is the 4180B which is currently the only board to get.

Proposed Solution

Could you add board-support for this hardware?

I tried also to run the lighting-app example with source from last test event for 4180A on my 4180B, but i am running in a error:

4180 board is from MG21 family and it lacks RAM memory to support matter applications. We have stopped matter support for that family a while ago.
