Uninitialised data relocation (.NoInit)

[GeorgePriestner-Eaton]

Are there any examples available for relocation of data to an uninitialised RAM section (e.g. .NoInit)?

Like how we specify sections with ARM compiler:
__attribute__((section("NoInit"),zero_init))

and the linker script e.g.

  RW_IRAM1 0x20000080 0x0003FF80  {  ; RW data
   .ANY (+RW +ZI)
  }
  RW_IRAM2 0x20000000 UNINIT 0x00000080  { 
   *(NoInit)
  }

I'm using an STM32F429zi.
