TMDSEVM6670L 60-pin DSP JTAG question

Other Parts Discussed in Thread: TMS320C6670

Hello again.

Here's hardware question about an 60-pin JTAG port on the board. Can i connect the another device  (preferably like other board like this one), with the special connector of course?

    Hi Taras,

    I did not understand your question.

    EMU1 is a high speed system trace capable TI 60-pin JTAG connector for XDS560v2 type of DSP emulation. The on board switch multiplexes this interface with the on board XDS100 type emulator. Whenever an external emulator is plugged into EMU1, the external emulator connection will be switched to the DSP. The I/O voltage level on these pins is 1.8 V. So any 1.8V compatible emulator can be used to interface with the TMS320C6670 DSP. It should be noted that when an external emulator is plugged into this connector (EMU1), on board XDS100 type emulation circuitry will be disconnected from the DSP.

    What do you mean by another device? I think it is not possible. Please refer EVM TRM for pinout information from below link.

    Thank you.

    Of course. I've made a JTAG connector , so i can hook up another device to my evaluation board. I've needed to debug the device with the same processor, but without an JTAG and Usb emulators. So now, when the other device will be ready, i can use the TMDSEVM6670L evaluation board like "connection buffer"

    Hello Taras,

    Could you please explain the connection with help of a block diagram ?
