CCS/RM41L232: By SL_SelfTest_CCMR4F CCM selftest failed

Part Number: RM41L232


Tool/software: Code Composer Studio

Hello,

I am working on RM41L232 and using SafeTI 2.3.1. As follows by using SL_SelfTest_CCMR4F  I want to implement CCM periodic selftest functionality.

retVal=SL_SelfTest_CCMR4F(CCMR4F_SELF_TEST, TRUE, &failinfoCCMR4F);

The function returned failure.

By step debug I found that program stopped the following point.

while(!(SL_SelfTest_Status_CCMR4F(config)))

{

}

At this time register view is as follows:

CcmR4_Sr:0x00000000

CcmR4_KeyR:0x00000006

From these information would you like help me to analyze why CCM selftest failed?

    Hi Lily,

    You won't be able to see the result of CCMR4 test in debug mode.
    You need to program your code onto the flash memory of your device (Make sure that you trigger the GIO in the program once the CCMR4 test completes to indicate successful completion of the test). Disconnect the JTAG cable from your device PCB board and recycle the power supply. The CCMR4 test should work.

    Get back to us if you still face the problem.

    Kind Regards,
    Sagar
