EFR32 lighting-app build fails for 4180A #8744

Problem

On current master the lighting-app build for BRD4180A fails with error message:

Building the example for 4161A works

Noted, but BRD4180A cannot currently run matter examples as the RAM usage exceed the available 96kB of ram of the EFR32MG21

kai0989 commented 3 years ago

I tested the BRD4180B with the exampel from last test event, is this also broken due RAM-issue?

jmartinez-silabs commented 3 years ago

Yes both of those boards use MG21 which only has 96kB of RAM. Can I ask you for what company you work for? Do you have an applications engineer assigned at silabs?

kai0989 commented 3 years ago

I'm working for trilux, i'm also signed in silabs.

jmartinez-silabs commented 2 years ago

We stopped supporting BRD4180B (EFR32MG21 families) in Matter due to their RAM limitations. Unclear if/when those parts will be supported again in the near future as matter ram usage is way past 96kb currently
