XDS100-V2 OLIMEX JTAG

Other Parts Discussed in Thread: TMS320C6678

Hi everyone

I am starter with TMS320C6678 and i want to program this core with XDS100-V2 JTAG also i have the TMDXEVM6678LE that it has a spartan core but i want to use a Virtex 6 core instead of spartan. What program must be in the FPGA core for connecting the DSP processor? When i do not program the FPGA, I can not connect the DSP and i receive the Error:2131 on the code composer studio. I know that i must set the reset sequence with FPGA but i don't know what is the reset sequence. do you have the vhdl code for spartan on TMDXEVM6678LE?

    Hi Armin,

    The JTAG for the FPGA on the TMDXEVM6678LE is not connected to the XDS100 and cannot be programmed using that interface. A separate connector for the FPGA JTAG can be found on the board. This can be used to program the FPGA using a Xilinx programming pod. Note that the FPGA is not provided for customer development and must be programmed with the factory provided bit file for proper operation. This bit file can be found on the Advantech website.

    http://www.advantech.com/Support/TI-Evm/6678le_download3.aspx

    The Advantech website also provides an example of the RTL code to demonstrate the function of the FPGA. The EVM is only guaranteed to operate with the factory provided bit file.

    Regards, Bill

    Hi Bill

    I have not any problem with programming the spartan on the TMDXEVM6678LE board. I can program this FPGA with XILINX JTAG. I want to connect to the tms320c6678 without using factory's bit file. I know that i must control reset sequence. I do follow step:

    1. I had set the power sequence on the board

    2. I set the DSP_RESETZ signal after 5 ms

    3. I set the DSP_PORZ after 5ms

    4. I set the DSP_RESETFULL after 5 ms

    after all I built a new target configuration with CCS V5 and when I want to connect to board i can't because I had the Error 2131. I want to know what was the factory's bit file for connecting to board not for anythings other.

    do you know how i can connect to board?

    Hi Armin,

    As I stated, we are not supporting customer modification of the FPGA on the EVM. The details of the FPGA can be found in the EVM technical reference manual and in the RTL code on the Advantech website. This code includes the basic logic needed to initialize the board and control the interfaces shared with the expansion connector. No change to the FPGA is necessary to use the EVM. More details can be found at the following post.
