TMS320F28388D: Flash Erase

Part Number: TMS320F28388D
Other Parts Discussed in Thread: C2000WARE

Hi, 

I using F28388D controller, i am facing a strange behaviour.

I am running a individual scheduler of  500 micro sec, i am able to copy the data into the FLASH Sector 7,8,9 . but when i try to erase the sector 13 for CPU1 it does not happen i have a watchdog refresh at 10ms, but the same functionality works fine in CPU2 i can erase the sector 13. not understanding the difference in behaviour in 2 different CPUs

steps followed to erase the sector:

Flash_claimPumpSemaphore(FLASH_CPU1_WRAPPER);

Fapi_initializeAPI(F021_CPU0_BASE_ADDRESS,CPU_FREQUENCY_MHZ);

Fapi_setActiveFlashBank(Fapi_FlashBank0);

Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,0xBE000);

while (FdFlashOperationStatus() != Fapi_Status_FsmReady){}

FdFlashEraseVerify(0xBE000);

gstrCpu1IpcRegs.PUMPREQUEST.all = FLASH_PUMP_KEY (0x5A5A0000UL)

The macros used is provided below

typedef enum
{
FLASH_CPU1_WRAPPER = 0x2, //!< CPU1 Wrapper
FLASH_CPU2_WRAPPER = 0x1 //!< CPU2 Wrapper
}Flash_PumpOwnership;

//Define to map the direct access to the FMC registers
#define F021_CPU0_REGISTER_ADDRESS 0x0005F800

//Define to map the direct access to the FMC registers.
#define F021_CPU0_BASE_ADDRESS ((Fapi_FmcRegistersType *)F021_CPU0_REGISTER_ADDRESS)

#define CPU_FREQUENCY_MHZ 200

the same is followed every time erase is called . What could be the problem for this any pointers to check

Thanks,

Nagesh
