AM2634: Using ECC with SysConfig

Part Number: AM2634
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi

In the latest SDK (TI_mcu_plus_sdk_am263x_10_02_00_13) it is possible to configure the SDL via SysConfig. There are no examples how to use it correctly.

While CCM/ESM worked great, I face multiple problems when trying to detect ECC errors in L2RAM and TCM:

- Init for R5FSS0_CORE0_ECC_AGGR / SDL_R5FSS0_CORE0_ECC_AGGR_PULSAR_SL_ATCM0_BANK0_RAM_ID leads to a crash.
- Init for SOC_ECC_AGGR / SDL_SOC_ECC_AGGR_MSS_L2_SLVx_ECC_RAM_ID works, but when an error is injected, ESM callback is not called, although the corresponding interrupt has been activated

Is there anything important to now? I assume that the ECC has already been activated on these memory modules in the bootloader (sbl_qspi).

Thanks for any help.

    My sincere apologies for delayed response.

    We tested this on our side, and we didn't see any issues in execution.

    Here is our output:

ECC Example Application

ECC UC-1 and UC-2 Test 

ECC_Test_init: Initialize of MSS L2 ECC Memory is complete 

ESM_Test_init: Init MSS ESM complete 

ECC_Test_init: MSS L2 ECC initialization is completed 

MSS L2 RAMB Single bit error inject: starting 

ESM Call back function called : instType 0x2, intType 0x1, grpChannel 0x0, index 0x13, intSrc 0x13
 
Take action 

High Priority Interrupt Executed

ECC Error Call back function called : eccMemType 0, errorSrc 0x1, ramId 2, bitErrorOffset 0x00000002, bitErrorGroup 0

MSS L2 RAMB Single bit error inject at pErrMem = 0x70100008 and the value of pErrMem is 0x00000000 :test complete

Waiting for ESM Interrupt

UC-1: Injected 1-bit error and got ESM Interrupt 

MSS L2 RAMB Double bit error inject: starting 

ESM Call back function called : instType 0x2, intType 0x1, grpChannel 0x0, index 0x14, intSrc 0x14
 
Take action 

High Priority Interrupt Executed

ECC Error Call back function called : eccMemType 0, errorSrc 0x2, ramId 2, bitErrorOffset 0x00000001, bitErrorGroup 0

MSS L2 RAMB Double bit error inject: pErrMem fixed location = 0x70100008 once test complete: the value of pErrMem is 0x00012002

Waiting for ESM Interrupt 

UC-2: Injected 2-bit error and got ESM Interrupt

All tests have passed.

    Check this one once and if needed we can setup one live debugging session.
