TMS570LS1224: TMS570

Part Number: TMS570LS1224

Hi,

I want to run boot-time and run time diagnostics on MPU by checking  functionality of the non-CPU bus master MPUs (7.130 Software Test of MPU Functionality). The safety library provides this functionality for DMA  only but we are not using DMA in our design. Need your inputs, how to implement on other components such as SRAM, MibSPI or MibADC.

Regards,

Abdul

    Hello Abdul,

    Both CPU and DMA have memory protection unit, and the MPUs are built in the bust master (CPU, or DMA). If you don't use DMA, you can configure the CPU MPU to protect the SRAM, and peripheral RAMs and peripheral registers.

    Through CPU MPU, the SRAM can be configured as user ready only, and any CPU write to SRAM will generate an error. 

    The SRAM memory range is from 0x08000000 to 0x0802FFFF

    The MibSPI RAM is from 0xFF0A0000 to 0xFF0FFFFF
