TDA4VM: XJ721E6BALF

Part Number: TDA4VM

Hi:

 the r5f in MCU Domain can access modules and peripherals that placed other domains?

the code is in directory :

ti-processer-sdk-rtos-j721e-evm-7_03_00_07/pdk_jacinto_07_03_00_29/packages/ti/boot/sbl/board/k3/

code is in sbl_main.c

i see that SBL code configure MPU region 4 for access 2GB DDR RAM, but DDR is in main domain.

And SBL can config GTC timer that placed in main domain.

    The MCU R5F can access peripherals in the Main domain, it can access IPs, memories etc. across domains.

    Cross domain access are possible in HW, however these can be policed.
