RM48L952: HALCoGen FEE example stuck waiting on TI_Fee_GetStatus()

Part Number: RM48L952
Other Parts Discussed in Thread: HALCOGEN

Hi.  I am trying to get the HALCoGen FEE example to work with the RM48 HDK (RM48L952ZWT).  The program loops forever waiting for the call to TI_Fee_GetStatus() to return IDLE.  It always returns 0.

The example is code is from: C:\ti\Hercules\HALCoGen\v04.07.00\examples\RM48x\example_TI_Fee_Write_Read.c

It is linked with the F021 little endian library recommended: F021_API_CortexR4_LE_V3D16.lib.

The relevant screen shots from HALCoGen are:

I am using the IAR IDE. The screen shot below shows point where the code loops forever. 

Please recommend how I should proceed. I will need to save parameter data to flash in our target design and proving it can work on this demo board is necessary. Thank you.

    Hi Shawn,

    Can you remove the delay in do-while() and try again?

    TI_Fee_Init();
    do
    {
    TI_Fee_MainFunction();
    }while (TI_Fee_GetStatus(0) != IDLE);

    What is the MPU setting for FEE memory? Is it protected? What is the wait state settings for flash/EEPROM? Your CPU frequency is 220MHz, the ewait should not be less than 3. Please check the register: EEPROM_CONFIG

    Thank you for your reply. I am not sure exactly what I was doing incorrectly in the example. But I now have flash working OK in my target project. I will close this issue.
