TMS570LS0432: esmInit or SL_ESM_Init(ESM_Applica..) problem

Part Number: TMS570LS0432
Other Parts Discussed in Thread: HALCOGEN

Hello

 Team

 I use the library demo. In the startup.c  ,which the code is

esmInit();
/* initialize copy table */
__TI_auto_init();

SL_ESM_Init(ESM_ApplicationCallback);

A few days ago, the ECCbit failure of my setting has not been interrupted, and it is found that  the problem is ，if I cancel the SL_ESM_Init(ESM_ApplicationCallback);

that the interrupt function is normal. but the demo have the SL_ESM_Init(ESM_ApplicationCallback);

 I want to know Why did he not interrupt it? Should I cancel or change SL_ESM_Init code?

    Hello Whong,

    If SL_ESM_Init() is not called, the esmHighInterrupt(void) is the ESM interrupt ISR. This is defined in vimInit().

    After SL_ESM_Init() is called, the ESM interrupt ISR is re-defined as sl_esm_high_intr_handler() which is located in sl_esm.c

    Please add a breakpoint in sl_esm_high_intr_handler() or in the callback function  ESM_ApplicationCallback() to monitor if the interrupt is generated by 1-bit ECC error.

    Thank you

     Yes ,If I use the SL_ESM_Init()，the program go into the  ESM_ApplicationCallback()

    and go into  here 

    else if((ESM_GRP1_MASK == ((grp_channel&ESM_GRP1_MASK)))&&(ESM_G1ERR_B0TCM_CORRERR == (grp_channel & 0x0000ffff)))
    {
    callbkParam1 = param1;
    /* clear nError PIN and esm flags */
    sl_esmREG->SR1[0] |= GET_ESM_BIT_NUM(ESM_G1ERR_B0TCM_CORRERR);
    BIT_SET(sl_tcram1REG->RAMERRSTATUS,TCRAM_RAMERRSTATUS_ADDR_SERR);/* Clear for subsequent operation */
    BIT_SET(sl_tcram2REG->RAMERRSTATUS,TCRAM_RAMERRSTATUS_ADDR_SERR);
    _SL_HoldNClear_nError();
    sram_1bit_prof_faultinject_callback = TRUE;
    }

    But  the library 2.4 code  dont have the Infinite loop，I think it should be added it

    What are the benefits of safety library2.4? Compared with the automatic generation of HCG software

    Hi Whong,

    HALCoGen was developed before SafeTI diagnostics library hence there are few overlapping Safety Diagnostics features between them. We strongly recommend to use SafeTI Diagnostics library for Safety Functions.

    _SL_HoldNClear_nError();
    sram_1bit_prof_faultinject_callback = TRUE;
    }

    Should I add an infinite loop，in that  code.

    Hi Whong,

    If 2-bit ECC detected, data abort is generated, and custom_abort_handler should be called if the 2-bit ECC error is not caused by selftest. 

    For 1-bit ECC error, the SRAM data is corrected and restored to SRAM. An infinite loop is not required here.
