Problem with connecting the target

Other Parts Discussed in Thread: TMS320DM6437

I m using CCSv4. I m trying to communicate my target board (TMS320DM6437) with Black hawk USB560bp emulator.

When I try to debug a  simple Hello World program(with main.c and target config file), the IDE is able to launch BlackHawk Emulator

but later while writing the code into the target memory, it gives the following error.

C64XP_0: Trouble Reading Memory Block at 0x20 on Page 0 of Length 0x4: (Error -1190 @ 0x20) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Release 5.0.429.0)
C64XP_0: File Loader: Data verification failed at address 0x00000020 Please verify target memory and memory map.
Error found during data verification.
Ensure the linker command file matches the memory map.

I have also tried changing settings in Target Configuration. Yet no use.

More over in the Target menu, I always find the Connect/Disconnect, debugging options inactive.

Unfortunately there is no Getting Started User guide for CCSv4.

Can anyone please let me know a brief about How to Program/Debug a simple code in my board.

    The error is likely due to not specifying a linker command file when building your project. If you do not specify a linker command file, the linker will perform some default allocation of code and data which may or may not match up with the actual memory on the target.

    This post tells you where you can get a linker command file for DM6437. Download and add this to your project and rebuild.

    Although not specific to getting started with your board, there is a Getting started guide for CCSv4 here that should help you with getting familiar with CCSv4 in general:

     In addition, this wiki page contains a lot of additional details on CCSv4: http://processors.wiki.ti.com/index.php/Category:Code_Composer_Studio_v4

    Hi,

    The information you provided was pretty helpful. Yet I m stuck in the last part.

    Now, I ve added the linker command file and .GEL file, which on debugging is executed as below

    I doubt few things. Please answer them.

    FASTBOOT, BOOTMODE[3:0], AEM[2:0],AEAW[2:0]. I have all these pins on user configurable jumpers.

    How do I handle these pins? Are they really causing problem?

    Currently using

    Emulation Boot (BOOTMODE[3:0] = 0000b, FASTBOOT = 0 or 1)

    Debugging via BH-USB560-bp.

    The boot mode settings seem ok. I would suggest first trying to run some of the tests that come as part of the Spectrum Digital content for this EVM (http://c6000.spectrumdigital.com/evmdm6437/reve/ - EVM Target Content). These are set up to build and run out of the box. They are set up for CCS 3.3 but you should be able to import them into CCSv4 and the project import wizard should be able to convert the project. Once you get these working, you can move on to creating your own examples using the provided examples as a starting point.

    Also be sure to use the latest version of CCS, v4.2.4 to avail of bug fixes to date.

    Please explain me the following commands in the linker file. Hope I can modify as per the error I m getting.

    Please rename the file evmdm6437.txt as evmdm6437.gel, linker.txt as linker.cmd
