    Hi,

    nERROR signal is driven by ESM Module.

    Please check ESMSR1/2/3 registers which should let you know the exact cause for nERROR.

    Hi,

    Please refer to the DataSheet of the part you are using.

    Regarding ESMSR3=0x80, its most likely Flash Module uncorrectable Error, (FMC - uncorrectable ECC error: bus1 and bus2 interfaces). If this is the case, then you should further look in to the Flash Module Controller specification to root cause the exact location of the failure.

    Best Regards,

    Karthik.

    At my main loop program ,the code is behind ,  use CCSV5.3

    nERROR will light after run logSendBuf() twice

    when it don't use  delay() at while(1), nERROR will not light, give me some suggestion. Thank you

    while(1)
    {

    GPIOSet(D4,1);//gioSetBit(gioPORTB, 0, 1); //portb0
    GPIOSet(TESTLED,1);//gioSetBit(hetPORT1, 28, 1); //D15

    delay();
    GPIOSet(D4,0);//gioSetBit(gioPORTB, 0, 0); //portb0
    GPIOSet(TESTLED,0);//gioSetBit(hetPORT1, 28, 0);

    logSendBuf(m_data_out,6); //mibspi dma send

    delay();
    }

    void delay(void)
    {
    unsigned int i;
    for(i=0;i<6000000;i++);
    }

    Help me see  my project, debugging for several days, it has not been resolved. When using the "delay()" in the "while" function, the MCU error lamp will light up.

    Thank you !

    looked forward
