Trying to get started, examples do not build

Hi,

 

I'm trying to get started with an C6748LCDK. I've loaded the facedetect demo in CCS and when I hit build, I get the following short output:

***************************************

"C:\\ti\\ccsv5\\utils\\bin\\gmake" -k all

'Building file: ../facedetect_lcdk.cfg'

'Invoking: XDCtools'

"C:/Program Files (x86)/Texas Instruments/xdctools_3_23_00_32/xs" --xdcpath="C:/Program Files (x86)/Texas Instruments/bios_6_33_01_25/packages;C:/ti/ccsv5/ccs_base;" xdc.tools.configuro -o configPkg -t ti.targets.C674 -p ti.platforms.evmOMAPL138 -r debug -c "C:/ti/ccsv5/tools/compiler/c6000_7.4.1" --compileOptions "-g --optimize_with_debug" "../facedetect_lcdk.cfg"

The current directory is invalid.

gmake: *** [configPkg/compiler.opt] Error 1

gmake: Target `all' not remade because of errors.

**************************************

I've no idea which directory it refers to nor what should be wrong.

When I try to load the mcasp example (from starterware) I get a lot of the following error:

***********************

warning: library

   "../../../../../../../binary/c674x/cgt_ccs/c6748/system_config/Debug/system_

   config.lib" contains ELF object files which are incompatible with the

   TI-COFF output file.  Ensure you are using the proper library.

**************************

And of course the resulting "unresolved symbols" error.

Finally I tried creating a new project in CCS, based on the "Hello World" example. It compiles fine, but when I try to load in on the board I get this error:

********************

Error connecting to the target: (Error -2131 @ 0x0) Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).

*********************

I've no idea how to continue from here.

It seems though that the board is working fine, as I can load the binary pre-compiled mcasp example and it works great (loaded over the UART)

 

Thanks in advance.

 

Kind regards,

    I go the luminious idea to change the output format of the mcasp exmple to eabi, as it noted "ELF". I do know get the following errors:

    ***************

    "../mcaspPlayBk.cmd", line 18: error: L1P memory range overlaps existing memory range SHDSPL1PRAM

    "../mcaspPlayBk.cmd", line 19: error: L1D memory range overlaps existing memory range SHDSPL1DRAM

    "../mcaspPlayBk.cmd", line 20: error: L2 memory range overlaps existing memory range SHDSPL2RAM

    "../mcaspPlayBk.cmd", line 21: error: DDR2 memory range has already been specified

    "../mcaspPlayBk.cmd", line 21: error: DDR2 memory range overlaps existing memory range DDR2

    ***********************

    I've not changed anything in the mcaspPlayBk.cmd, as I assumed it would be setup correctly as an example.

    Where can I find information on how to setup this memory configuration?

     

    Regards,

    Hi Remco,

                Kindly take a look at the following thread which talks about the same issue and upgrading the CCS to latest version resolves the issue.

    http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/132000.aspx

    If the problem persists, let us know the CCS version you are using to build the project.
