Trey,

The example does work. Here is your .cmd

I deduce from this data that RamfuncsLoadStart is the start of the .text section as defined by LOAD = FLASH_N | FLASH_M; that RamfuncsLoadEnd is the end of the actual code consumed by the allocation of all the ramfuncs .obj files, and that RamfuncsLoadSize is this length. In a similar fashion, RamfuncsRunStart is defined as the beginning of the ram section C0; that RamfuncsRunEnd is the end of the memory space required (same as RamfuncsLoadEnd), and that it's size is the same as RamfuncsLoadSize. Therefore, the values associated with these are automatically assigned and / or calculated by the linker and I do not need / cannot set the size of the data to be transferred to ram.

Are my assumptions correct?

Thanks,

Pat

All of your assumptions are 100% correct!

Trey,

I found that by removing my debug folder in the project list and reinstalling it, I could get some of the ram code allocated.  The _c_int00 address seems quite high for some reason. Also I have lost the driverlib.lib , Example_Error, and Example_Done. Here is my new map:

Any direction would be helpful, Thanks.

Pat,

_c_int00 is in the right place.  That address is a flash address so that is fine.  Typically we also link in the codestart_branch file which is designed such that when it links it resides in the "Boot to flash" vector address.

What do you mean by you lost driverlib?  Did you accidentally delete the lib file?  If so you can rebuild it by importing and building the driverlib project, just like you would with any other example.  I'm not sure about the other two functions you are missing.  Which example are you working with here?

Trey,

I am trying to incorporate your latest flash_prog example code into my current application.

What I meant is that the ramfuncs file flash.obj was not included in the map. I do have driverlib.lib included in both the projects list as well as a path to the dir location using the include options. It just doesn't get loaded. One difference is that I am using compiler 4.9.7 which is compatible with my application code vs v4.6.6 that you recommended. Could that be the problem? Is there a compromise?

Thanks,

Pat

I tried v4.9.7 for the flash example and it looks almost the same, at least it did include flash.obj and the two Example subroutines.

Pat,

The compiler version shouldn't cause any trouble.

The linker is only going to pull in what it needs.  From your map file it looks like it is pulling in the parts of driverlib that the project needs.

Is there something specific that is wrong when you run the application or are you just trying to understand the whole compile/link process?

I have moved the example code into my application and am trying to duplicate the test there. The code hangs up at the point Fapi_GetBankSectors. If I comment out that code, it passes thru the code OK.

???

Pat

Excellent, now we are getting somewhere.

Are you calling FlashGainPump() before calling any of the Fapi functions?

When you say it hangs, what do you mean?  Do we hit an ITRAP instruction? Does the CCS window go blank only showing an address in the debug window?

Yes, I call FlashGainPump() before entering this code: I get a FaultISR when it hangs. The Example_Error and Example_Done functions have been commented out so they return, but when I enable the Error function, the code never seems to get there.

// COM_TX((UINT8*)&oFlashStatus,4);

// COM_TX((UINT8*)&oLibInfo,4);

return oReturnCheck;

}

The code will run all the way through the programming function, but then seems to get lost somewhere. Here is some data from the watch window, followed by the .cmd file. Perhaps I need to segment all my flash sectors into 16k blocks like the 2 sectors that were set in the example???.  I would appreciate some direction here.

oReturnCheck = Fapi_Error_Fail
oLibInfo = {...}
 u8ApiMajorVersion = .
 u8ApiMinorVersion = 4
 u8ApiRevision = .
 oApiProductionStatus = Production
 u32ApiBuildNumber = 220
 u8ApiTechnologyType = .
 u8ApiTechnologyRevision = .
 u8ApiEndianness = .
 u32ApiCompilerVersion = 4009006
oFlashBankSectors.u32NumberOfSectors = 14
oFlashBankSectors.u32BankStartAddress = 2097152
oFlashBankSectors.au8SectorSizes = 0x20007D3C
 [0] = .
 [1] = .
oFlashStatus = 0

Pat,

You might be getting an ECC error.  Could you try running your application with ECC disabled?

FlashInit function can be modified to disable ECC.  See below code snippet from this function.

        //At reset, ECC is enabled

       HWREG(FLASH_ERROR_BASE + FLASHERR_O_ECC_ENABLE) = 0xA;

In above code statement, instead of writing 0xA, write 0x0 to disable ECC as below:

       HWREG(FLASH_ERROR_BASE + FLASHERR_O_ECC_ENABLE) = 0x0;

Thanks and regards,

Vamsi

Vamsi,

That didn't make any difference. I also re sectored my flash to more correspond with the example as such:

Still doesn't work. I'm just clutching at straws here in order to find something that works.

The PLC example that I started with used "FlashPump()". I commented this out, but is there some conflict here?

Thanks,

Pat

oFlashBankSectors.au8SectorSizes (14) all are set to zero apparently, according to the Watch data when I break following Fapi_getBankSectors. Is there some reason why this value is not the value set in the .cmd file?

Pat

OK, I think I found part of the problem. In your example flash_program, you disable hardware protection and never reenable it.  In my application, I disable hardware protection in order to setup the sys clock, then reenable it. Doing this causes the flash programming to fail. Removing the reenable allows it to work, but my app fails when I am configuring my GPIO. What's the proper procedure?

Thanks,

Pat

My PLC app uses the following flash pump code:

// set up flash pump

void

FlashPump(void)

{

#define

IPC_MPUMPREQUEST_KEY 0xA5937EC0

// Key Value

HWREG(MTOCIPC_BASE + IPC_O_MPUMPREQUEST) = IPC_MPUMPREQUEST_KEY | 0x2;

}

I cannot find any reference to FlashGainPump in the latest Flash API. What does FlashGainPump do? This may be part of my problem. Any help, please?

Thanks,

Pat

Pat,

I just got the flash API in my concerto project to work. I adapted the example delivered with the flash API library.

The C28x and the M3 share one flash pump so they have to claim this ressource to protect for each other. Figure 5-78 in the TechnicalReferenceManual (spruh22c) shows it quite clearely. A description how to deal with this semaphore is found in the TRM section 1.12.7 of the TRM.

The simple functions FlashGainPump() and FlashLeavePump() are part of the MWare/driverlib of ControlSuite.
Before Gaining the pump I have added a check whether this semaphore is available so my application can return with an error. It looks like this

#pragma CODE_SECTION(IsFlashPumpIdle,"ramfuncs");
/*******************************************************************************
* \fn static BOOL IsFlashPumpIdle(void)                                         
********************************************************************************/
/*!\param     -                                                                 
*                                                                               
*  \remarks   Checks if FlashPump Semaphore is available          
*                                                                               
*  \retval    success                                                     
********************************************************************************/
static BOOL IsFlashPumpIdle(void)
{
  return HWREG(MTOCIPC_BASE + IPC_O_MPUMPREQUEST) == 0;
}

FLASHARM_RC_T AppFlashArm_foo(void)
{
  ...
  if (!IsFlashPumpIdle())
  { // Semaphore is not available
    return FLASHARM_RC_APP_PUMP_BUSY;
  }

  FlashGainPump(); // Gain flash pump semaphore
  ....

Hope this helps,
Stefan
