Hi,
I saw there is no demo for EFM32GG11 from Silabs (Cortex-M4 CPU based) and also this post learned me there is no official port while FreeRTOS support this Cortex-M4 core.
Do you know if there is already a port for EFM32GG11 planned and then, how long it will take to complete this one and what is done or missing currently?
Many people know a lot more about this subject, about as a quick answer: any Cortex-M4 can use the generic FreeRTOS M4 port. That is the power of ARM: code can be reused among platforms.
Have a look at the ARM_CM4F or ARM_CM4_MPU directories, for instance portable\GCC\ARM_CM4F
