Tool/software: Code Composer Studio

Hi all,

We are developing a motor control system with 3 TMS320F28054Ms as controllers of 3 axes and a TMS320F28055 as control manager. Software tool is Code Composer Studio(Version: 6.1.2.00015) and control program based on motorware_1_01_00_17. All chips work at 60 MHz frequency. The communication between 3 TMS320F28054Ms and a TMS320F28055 uses SICs. All things are great right now.

We want to save some parameters into TMS320F28055's FLASH. So we tested flash programming with \TI\controlSUITE3.4.4\libs\utilities\flash_api\2805x\V100\example_ccsv5 project. The testing is all right.

But after I ported flash programming example into my TMS320F28055 control manager, I had troubles.

PIE Vector SARAM Locations used by the Boot ROM set as:

0x0D02 Flash_CPUScaleFactor 0xFF04 0x00BF(Decimal 12,582,660)

0x0D04 Flash_CallbackPtr NULL

After I run ' Flash_Erase((SECTORB),&FlashStatus) ' instruction by step over command my program stopped at 0x3FF67B (into Bootloader zone).

Who can help me to solve the problem. Thanks in advance.

Winston,

If your PC is at 0x3FF67B, then your PC is waiting in PARALLEL BOOT. So, your CPU had received device reset.

Check whether BOR (or) WD had reset your device.

Manoj

Hi Manoj,
Is there anything I need to pay close attention to when I copy the Flash2805x_API example from controlSuit to MotorWare's lab? The code structure and the way they define variables are different.

When I added Flash2805x_API code into Motorware's lab, the Flash_Erase function doesn't work correctly. I tried to follow the extract same settings from Example_Flash2805x_API,I ran into same problem as Winston did.

Any suggestions?

Qiang,

Please check the below Flash API reference guide. It tells the do and don'ts with Flash API. It also provide a checklist on what needs to be done.

Hi Manoj,
I followed the exact same settings as controlSuit example, but my program suck inside Flash_Erase(), it can't come out. It doesn't report any error.

Hi Manoj,

I had checked BOR (or) WD. They did not reset my device I think. WDCR always is 0x0040 and the voltage of power supply keeps stable. Is there anything else to reset my device? Why is the project (\TI\controlSUITE3.4.4\libs\utilities\flash_api\2805x\V100\example_ccsv5 ) correct?
