LAUNCHXL-F280049C: Serial Flash Programmer

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: C2000WARE

Hi,

I am using serial flash programmer to load application via sci pins. I compiled serial_flash_programmer.cpp by using visual studio.

In command arguments I execute the command as shown below:

-d f28004x -k D:\ti\C2000Ware_3_03_00_00\utilities\flash_programmers\serial_flash_programmer\f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel.txt 

-a D:\ti\C2000Ware_3_03_00_00\utilities\flash_programmers\serial_flash_programmer\f28004x_fw_upgrade_example\led_ex1_blinky -p COM4 -b 9600

when i clicked on start debugging CPU1 kernel commands is coming. I selected option 1 DFU CPU but code is not loading into flash.

I set my GPIO pins as GPIO 24 0n 0 and GPIO 32 on 1 for SCI boot.

It is running fine when I am loading SCI_FLASH_KERNAL using CCS studio then I commented line //define kernel in serial_flash_programmer.cpp and by using the same command arguments as written above .In this case it is working fine.

I want to know that can we directly load application into flash by using serial flash programmer or not?

I attached the image of command window below

    Deepak,

    Yes, what you're trying should work.

    Can you try this - build the CPU1_RAM build configuration of the flashapi_ex2_sci_kernel project (the same one you successfully download via CCS), copy the resulting .txt file into C2000Ware_3_03_00_00\utilities\flash_programmers\serial_flash_programmer\f28004x_fw_upgrade_example (overwrite the existing .txt file). Then try running it with the commands, and see what you find.

    d f28004x -k D:\ti\C2000Ware_3_03_00_00\utilities\flash_programmers\serial_flash_programmer\f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel.txt 

    -a D:\ti\C2000Ware_3_03_00_00\utilities\flash_programmers\serial_flash_programmer\f28004x_fw_upgrade_example\led_ex1_blinky.txt -p COM4 -b 9600

    A couple of side observations:

    - your command sequence is missing the .txt for the LED application file. I've pasted it in bold. Not sure you typed it, or pasted it.

    - the picture you sent indicates a "led_ex1_blinky.txt Does it exist?" issue. Confirm the file is there. And it seems to be printing the path twice. Not sure why.

    - Please use the prebuilt serial flash programmer executable instead of building it in Visual Studio. See if that helps. Note that serial_flash_programmer.exe is the executable that sends both the kernel and the application, and the serial_flash_programmer_appln.exe is the executable that sends only the application (i..e define kernel is commented out)

    Thanks,

    Sira

    Hi Sira,

    Thanks for the reply. Now I have more clarity about serial flash programmer.

    I did the same what u suggest but it is not working, command prompt is coming like this as shown below

    Deepak,

    Sorry for the delayed reply. Dealing with power outages and other issues in Houston. I'll get back to you in a day or two.

    Thanks,

    Sira

    Hi Sira,

    No problem there is one correction in previous post COM port will be COM3. But continuous stream of data are coming kernel is unable to download.

    Hi Sira,

    It is working now thanks for your help.

    Actually kernel takes some time to download the data I thought it was not working.

    Hi Deepak, good to hear. Yes, when the kernel is downloaded, each byte is echoed, which is why it takes several minutes to download. The application downloads much faster.

    Good luck,

    Sira
