TDA4VM: SEC_MMR0 registers neither readable nor writable

Part Number: TDA4VM

Hi TI,

I wanted to read out the following registers:

  • SEC_MMR0_DBG_CTRL (0x4594 4000)
  • SEC_MMR0_BOOT_CTRL (0x4594 0000)
  • MCU_SEC_MMR0_DBG_CTRL (0x4595 0000)
  • MCU_SEC_MMR0_CFG0 (0x45A5 0000)

I can only read zeros for all of the above mentioned registers. I am aware, that I have to unlock CTRLMMR registers to make them writeable. If I understood it correctly, this only applies to CTRL_MMR0 registers and not to SEC_MMR0 registers. Additionally, I simply want to read form the registers und not write to them.

So can you give me a hint to read out the correct values from those registers?

Thanks and best regards,

Felix
