• If the erase request is successfully sent to the Flash

False:

• If Write enable fails before sending chip erase command to Flash
• If chip erase command itself fails

DRV_HANDLE handle; // Returned from DRV_SFDP_Open

if(DRV_SFDP_ChipErase(handle) == false)
{
    // Error handling here
}

// Wait for erase to be completed
while(DRV_SFDP_TransferStatusGet(handle) == DRV_SFDP_TRANSFER_BUSY);

None.
