ezDSP loses programming after being unplugged!

Timothy Sapio

I have a c5505 ezDSP module. I can program it however I want, but as soon as I unplug it from the USB port, it reverts back to the factory test code. How do I prevent this?

    Timothy,

    You need to burn your program to the SPI EEPROM of your eZdsp. For that, you need two things:

    1) Create a boot image using the hex55 utility. You can get step-by-step instructions here:

    http://processors.wiki.ti.com/index.php/C5000_Creating_Boot-Images

    2) Use a programmer.out file to burn the image to SPI. The programmer can be found at

    http://code.google.com/p/c5505-ezdsp/

    under "C5505 EZDSP programming tool"

    Load the program to your eZdsp using CCS, then input the file path to your boot image, and make sure it doesn't have any white spaces on the path or name of the file.

    If you need further assistance, let me know.

    Do you have the boot image created according to the wiki article?

    What exactly don't you understand to get the desired result (what step are you stuck on)?

    Regards,

    HI juliana 

     

    i work hard to learn how to make the boot image and i get good result after many experements

     

    but i have some problem with following :

     

    *can i make any project that i want as boot image and then burn it to nor flash , or there is certain specification for project ?

    since i try to make boot image for first project included in european university program for c5000 teaching room and install the image to c5515 ezdsp but no result i get


    *for this

    hex55 -i filename.out -o boot_image_file_name.bin -boot -v5505 -b -serial8

     

    are this used always in this form , or there is other combination can be used?

     

    thanks
