CCS/TMS320C6678: EVM6678L connecting issue :gel goes wrong

Lucius Green

Part Number: TMS320C6678

Tool/software: Code Composer Studio

error code:

IcePick_D: GEL: Error while executing OnTargetConnect(): identifier not found: DNUM
at GEL_TextOut("DSP core #%d\n", 0, 1, 0, 0, DNUM) [evmc6678l.gel:1976]
at Core_Info() [evmc6678l.gel:559]
at OnTargetConnect()

CCS 9.3   , EVM BOOT MODE:FIRST 0 ,ohter 1  

I have know that Feruz have the same problem ,he do some changes in xml files as Darian told him ,and it works.

But in my case ,it does't work.

I add <register id="DNUM"   acronym="DNUM"   width="32" description=""/> to  64x+NotVisible.xml ,it does't work;

I add <register id="DNUM"   acronym="DNUM"   width="32" description=""/> to c66xx_hidden_registers.xml,it does't work;

I have try all gels ,for example : C:\ti\ccs\ccs_base\emulation\boards\evmc6678l\gel , C:\ti\mcsdk_2_01_02_05\tools\program_evm\gel

and the one contended in the EVM DVD

I can get the value of DNUM in the register : DNUM 0x00000000 DSP Number[Core]

Can anyone give me some suggest?

    If you are running CCSv9.3.0 then the DNUM register is already defined on line 14 of c66xx_hidden_registers.xml.  I believe the comment from Darian is from 2012 and no longer applies.

    I am going to loop in the DSP team.

    Hi,

    Can you elaborate what you are trying to do? Are you using TI 6678 EVM or your own board? Is your board in the no-boot mode? The standard GEL is under \ccs\ccs_base\emulation\boards\evmc6678l\gel, what is your CCS version? The one in the MCSDK or DVD may be too old, although I expect that still work. I recall I used CCS 5.x, 6.x ... up to 9.3 in recent years and I didn't see any problem.

    >>>>I have know that Feruz have the same problem ,he do some changes in xml files as Darian told him ,and it works.>>>>> I don't have this conversion history, and I don't expect you need to change CCS xml file to make this working. Please just install CCS 9.3 (to a different location, don't mess with your existing c:\ti\ccs) and use the GEL file to try. if still fails, can you send me the full CCS console log when you connect to the device core 0?  

    Regards, Eric

         Thanks for your replay.

          I have uninstalled the ccs9.3 for many reasons,instead  I use version10.1 .Though 10.1 have some other issues but it can work with gel  ,and I can make my TMDSEVM6678L  board work,the leds are twinkling,it really make me excting and let me have intresting to learn dsp.

         CCS10.1 can't bulid a sys/bios project ,just like i post the problem in another question:e2e.ti.com/support/tools/ccs/f/81/t/941201,you told me how make it work,and it worked.Thanks again,Eric.
