LP-AM243: System Memory Map defines same address for multiple region

Part Number: LP-AM243

Tool/software:

Hi,

I am reading the datasheet for the AM64x / AM243x Processors (SPRUIM2H – May 2020, revised October 2023, Silicon Revision 2.0).

I noticed that the same address is assigned to multiple regions (specifically, COMPUTE_CLUSTER0_SS_ROM and DEBUGSS_WRAP0_EXT_APB0) in Table 2-1 "MAIN Domain Memory Map" on page 42.

My assumption is that EXT_APB0 allows the COMPUTE_CLUSTER0_... region to be disabled, so that a different debugging device can be used at the same address. However, I could not find any further information or clarification in the documentation.

Could you please explain the purpose of this address overlap, and under what conditions each region is accessible? Any additional references or documentation would also be appreciated.

Thank you!

  • Hello Petr,

    I see that you are referencing the AM243x / AM64x Technical Reference Manual (TRM), this section of the "MAIN Domain Memory Map":
