I owe a response to this, but haven’t had time to think about it in a lot of detail.

Because of this Silabs does not provide an extra development board, since binaries built for the EFM32JG12B can run on the EFM32PG12B. So the recommended development board for the EFM32JG12B is efm32pg_stk3402aSo I don’t know if renaming efm32pg12b to efm32Xg12b makes sense to cover the 2 variants.
2. Since there is no development board for the EFM32JG12B soc, i would like to add the possibility to the board efm32pg_stk3402a to compile for the EFM32JG12B instead of the EFM32PG12B. Is that possible or are there other recommendations?It should be doable, we have several boards that support different “configurations” already. Examples are the dual core SoCs in which we have one board dir but different <BOARD>_CFG.yaml and such for the different variants.
Not sure if that gives you enough to start with.
