F2837xd

Dear All,

We are working on F2837xD and we have designed our own board.  I have made sample project to test Basic LED flashing and it is first test program I would be loading to my new board. Same is getting loaded properly on control card without any problem. I am facing some problem while loading on new board.

I get following message on CCS6.0 console window.

 

C28xx_CPU1: GEL Output:
Memory Map Initialization Complete
C28xx_CPU1: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
C28xx_CPU1: File Loader: Data verification failed at address 0x00082000 Please verify target memory and memory map.
C28xx_CPU1: GEL: File: C:\Users\aakelkar\workspace_v6_0\f2837x_board\Debug\f2837x_board.out: a data verification error occurred, file load failed.

My boot load setting is load from flash.

I checked other details like, reset voltage, clock pulse etc. they are OK.

Since region 0x000820000 flash B region, I have also checked flash VDD pins. They are getting 3.3V.

Can any one give idea where could be problem? as I am using same .cmd file in both cases

Also in earlier versions of CCS to check Jtag connectivity, we had option of connect/disconnect processor . I am not sure how do I do it in CCS6. If I want to connect processor with out loading program , is there any way to do this?

not sure if it is possible?

regards

    Abhijit,

    The above errors indicate that perhaps CCS is not configured for the device you are using.  I would double check the configuration. 

    In both cases (control card and your custom board) were you able to connect with the same exact Code Composer Studio installation?   Make sure you have checked for updates for CCS.

    Here is a youtube video which provides some steps for testing the JTAG connection:

    This may also be useful.

    Here is a wiki which has some troubleshooting information for JTAG connections:

    Lori,

    thanks for reply.

    Yes Lori, CCS is correctly configured to Device I am using.

    Using help details you have attached, I complete JTAG scan test as directed in You tube video.

    Also using wiki help, I connected to my target by launching  Target configuration through View>Target Configuration>right click>Launch Selected target configuration.

    I have attaced screen shot of connected target . Here I could edit registor, view 0x00082000 memory area. It gave me relife that my board connection is not a problem.

    Am I having some other problem ? Or Am I missing some project set up related think?

    It works properly with control card connected with external JTAG (XDS200) but give data verification error to my board.

    Hi Abhijit,

    A few thoughts:

    1) Can you try to search & install any CCS updates?  (inside CCS, Help -> Check for Updates)
    (if I remember correctly, there was a slight change needed in CCS for it to program newer revision F2837x chips - you may be running into this)

    2) Are you able to load and run an example project that was designed to run from RAM?


    Thank you,
    Brett

    Hi Brett,

    Thanks for replying.

    Tomorrow I will check with update patch.

    Secondly, I already tried with importing control suite example project blinky. It works fine when code is running from RAM and gives same error when I try to run it through flash.

    Regards

    Abhijit
