DRA829J: R5F ECC of TCM default state

Part Number: DRA829J

Tool/software:

Hi team,

I'm currently developing a bootloader (running in MCU_R5_0) and I need clarification regarding the TCMs ECC.

  • Is the ECC of both ATCM and BTCM active by default by the ROM code?
  • Should I ensure the ECC activation during the bootloader initialization?
  • Can we read and change the ECC status? (using SciClient for example)

Note:
My understanding is that ROM activates the TCMs ECC.
I checked all R5s and the ECC is activated in all (in the Bootloader phase), plus I can see random values before initializing the TCM memories (fill with 0's), which I assume are from the ECC.
