CCS/TMS320F28377D: Running Application Code From CPU1 On-chip Flash

Tool/software: Code Composer Studio

Hello everyone

I'm recently upgraded myself from TMS320F28335 to TMS320F28377D and I'm newbie in dual core microcontrollers.

I loaded "gpio_ex1_setup" from "C2000Ware_1_00_01_00/driverlib/f2837xd/examples/cpu1/gpio/CCS/gpio_ex1_setup" into "CCSv8.1.0.00011"

and I added some additional code for togglling one LED on my custom board to the end of the main function as follows:

    GPIO_setPinConfig(GPIO_91_GPIO91);
    GPIO_setDirectionMode(91,GPIO_DIR_MODE_OUT);

    while(1)
    {
        DEVICE_DELAY_US(300000);
        GPIO_togglePin(91);
    }

its works fine in the "CPU1_RAM" configuration, but when i click right on the project and choose "CPU1_FLASH" from "Bulid Configuration/Set Active/CPU1_FLASH" menu,

the erase and program process begin and complete sucessfully and by restarting board "turning board power supply off and then on" nothing happens and LED does not blink.

What i missed?

Any help will highly be appreciated.

Hi,

Can you please check if the boot mode is configured for "boot to flash"?

Please refer section "4.3 Device Boot Modes" in the technical reference manual at www.ti.com/.../TMS320F28377D

Thanks,
Katta

Hi Katta
Thanks for reply.

The both GPIO84 and GPIO72 are pulled up to 3.3VDDIO (Configured to GET/Flash mode), and I checked them on the board and their voltages are 3.25Volt.

Hi,

After you program the code to flash, could you please step-in to the code till the control reaches your custom code.
Please let me know if you see any problem.

Also, could you please run the led blinky example at "C2000Ware_1_00_01_00\driverlib\f2837xd\examples\cpu1\led\" in FLASH configration and check if the led is blinking when you restart the board?

Thanks,
Katta

Hi

"After you program the code to flash, could you please step-in to the code till the control reaches your custom code.
Please let me know if you see any problem."

After programming code without turning board off, by clicking step into or run, the program works correctly, but still turning the board off and then on does not work.

"Also, could you please run the led blinky example at "C2000Ware_1_00_01_00\driverlib\f2837xd\examples\cpu1\led\" in FLASH configration and check if the led is blinking when you restart the board?"

The problem is the same in this case too.

Thanks

Hi,

Could you please try the gpio and led example from the latest c2000ware V1.00.06.00 from www.ti.com/.../C2000WARE

Thanks,
Katta

Take a look at C2000 Multi-day workshop - chapter 10 "System Design" includes a lab with full instructions on loading and running from Flash.

Hi,

It seems that the projects under "C2000Ware_1_00_01_00/driverlib" directory does not work correctly for me, but the projects in the "C2000Ware_1_00_01_00/device_support" section works without problem.

I will try the latest version of C2000Ware.

Thank you so much.
