hi, I am using CCS v2.0(eval) for 'c621x. I was running the example programs(related to dsp/bios) that comes along with ccs. In one of the programs, GEL control has been used to increase the load on cpu. and it also says that using GEL will halt the processor. so to debug in real time we go for RTDX. My doubt is : 1. When I use Gel to vary the load in CCS, how does this information gets transferred to physical DSP ??? Is it through JTAG interface (in case of custom boards). ?? If yes, what are the interface functions (in case of GEL control) between CCS and the program running on physical DSP ?? 2. Is there any way to save the on-line help that comes with CCS-2.0 30 day eval ??? thanks |

GEL ??

1. The information in GEL is transferred to the target via the JTAG emulation interface. GEL is a scripting language used in CCS and meant for debug. If you want access from the host to the target, for example, you may need an API that is supplied via a host library. One such library is the Win32 DLL on the DSK. It allows access of the DSP from a Windows program and is fully documented in the Help files for CCS. Please note this API assumes you are using the parallel port interface to the HPI on the DSP and NOT JTAG. There is another API which gives you access to the target via JTAG and that is RTDX, which is documented in CCS docs and app reports on the TI web. There is an API available in the CCS SDK, for developers to access the CCS functionality. This is meant primarily for creating plugins to CCS. 2. At this time there is no way for you to print the on-line help. But you may be able to get some docs, like the DSK help, from the TI Product Information Center. Regards, Tom Dillon |

Tom, This last point is an excellent reason to NEVER provide help files as the only means of documentation. I recently had to call the support line to try to get documentation on the C6711 DSK hardware. There is nothing on either of the CDs that came with the DSK (other than the schematic) and I could find nothing on the TI web site. The result of the call was that it is in the help files with the DSK version of CCS. I did find it there, but it is very limited and being in a HELP file is a major PITA!!! All I can say is... WHAT WERE THEY THINKING??? One simple PDF file with the block diagram, some notes on the operation of the functional blocks and a listing of each IO connector pinout with consistent signal names would be all that was required. Is this something that you need to contract out? I am available for consulting as a documentation engineer. :) Rick Collins Arius - A Signal Processing Solutions Company Specializing in DSP and FPGA design http://www.arius.com 4 King Ave 301-682-7772 Voice Frederick, MD 21701-3110 301-682-7666 FAX |
