EZDSP_Sample

Hi!

I am trying to burn my code into the EZDSP 5515 NOR permanently. I found a folder with spectrum digital named EZDSP_Sample which is suggested to be used as the base code so that the project could be written on EZDSP 5515.

As things go, I am unable to compile the project after importing it to CCS 4.1I have included everything needed to run codes for 5515 but getting Linker errors

 undefined    first referenced
  symbol          in file    
 ---------    ----------------
 _DMA_Isr     ./vector.obj   
 _I2S0_TX_Isr ./vector.obj   
 _I2S1_RX_Isr ./vector.obj   

error: unresolved symbols remain
warning: entry-point symbol other than "_c_int00" specified:  "reset_isr"
error: errors encountered during linking; "EZDSP_Sample.out" not built

>> Compilation failure
C:\Program Files (x86)\Texas Instruments\ccsv4\utils\gmake\gmake: *** [EZDSP_Sample.out] Error 1
C:\Program Files (x86)\Texas Instruments\ccsv4\utils\gmake\gmake: Target `all' not remade because of errors.


It will be highly helpful if somebody direct me as to burn my code onto the NOR flash. I have completely followed the instruction given in http://processors.wiki.ti.com/index.php/C5515_Boot-Image_Programmer but the code doesn't run in the DSP standalone.

    Hi,

     

    You need to compile it without error. Can you check your vector.asm file for _DMA_Isr, _I2S0_TX_Isr, and _I2S1_RX_Isr commented out?

    Regards,

    Hyun

    Hi Hyun!

    Thanks for the reply ...

    I have checked vector.asm and it all seems right their. For reference, this is what is there in vector.asm

             .global _DMA_Isr
             ;.global _SAR_Isr
             .global _I2S0_TX_Isr
             .global _I2S1_RX_Isr
             .global _RTC_Isr

     

    Kindly, let me know if I would be able to compile the EZDSP_sample myself and thus change it to burn my code permanently onto the device standalone.

    Thanks

    Solved the problem, the issue was that I had downloaded EZDSP_Sample from spectrum digital and extracted it in a non-standard location. There is similar folder present in ccs4/emulators/boards/usbstk5515 folder. If the project is imported from there without making a copy in the workspace, it works fine.

     

    Thanks everyone for the support.
