PROCESSOR-SDK-AM64X: ECC Aggregators

Tool/software:

Hi,

I am trying to figure out how to implement ECC Aggregators in order to catch memory errors in the ESM.

I seem to be having a hard time trying to figure it out.

I am confused on which aggregator corresponds to which module, or if I should just go ahead and implement all of the Aggregators.

1. Do the Aggregators match-up with the Modules? Does COMPUTE_CLUSTER0 matchup with a module along with; PSRAMECC0; CBASS0; GICSS0; MCU_CBASS0 (TRM pg 10144)

I am not sure how the aggregators match up with the modules. Are the modules, such as GPIO that don't have aggregators associated with them?

2.  What is COMPUTE_CLUSTER0. It seems to be correlated with GIC, but there really is no mention as to what it is, or what it does.

As per the previous question. I am not sure how all the aggregators correlate to modules.

3. What is an EDC checker for Aggregator Instance? Checks Parity?

I dont know the difference beween and aggregator and an EDC checker.

4. Does ESM Interrupt DDR16SS0_DDRSS_DRAM_ECC_CORR_ERR_LVL_0 Correlate to an Aggregator? (TRM pg 5827 Interrupt ID 6)

I am trying to match the Aggregator to a module, but I am not sure which module this Interrupt corresponds to

5. Where is ADC12_CORE_FIFO_RAM0_TPRAM_ECC in Memory?

6. There are 40 Aggregators, but there are multiple properties for the Aggregators and Multiple cores. 
How many are allowed to be implemented? Can they all be implemented?
(4 R5F Cores)
(29 Memory Sections)
R5FSS0 (29) * 4 = 116 
7. What is MSS L2 in Example Usage of MSS L2 in SDK Samples software-dl.ti.com/.../SDL_ECC_PAGE.html
MSS L2 Does not seem to be an aggregator
8. What is MSS TPTC Example Usage of MSS TPTC software-dl.ti.com/.../SDL_ECC_PAGE.html
MSS TPTC does not seem to be an aggregator

9. PSRAMECC is mentioned as a Module Instance in Table 12-5039. Does it correspond to a module listed in section 1.2.1 Module Allocation Instances within Device Domains

Again, I am not sure how aggregators matchup with modules.

Thankfully yours,
