I've just got my emulator recently from SEED and as I'm trying to program the evaluation board, I'm also thinking on designing other test boards for other C2000 DSP samples I collected since a while ago, untouched as yet.
Anyway, getting to business, I'd like to know how do I identify the pinouts, when the XDS100v2 terminals I have extends like these (Samtec) :
Let's say pin number one starts on the top left and ends on the bottom right, and according to what I read, the pins are designated like:
So any references or better, can anyone just point out the labels for the pins according to the image I inserted above?
Thanks a lot guys. I searched high and low for the right places to look at.

mmm... no takers? Have I missed something here? what I meant is that do I designate the pins like this?:
according to this table:
Hope this clears the air.
If you take a look at some of the various schematics and pcb layouts in controlSUITE you'll be able to copy this information out.
Attached is a JTAG interface that TI has on one of its boards. Note that this schematic is also labelled as it would physically look from above. Note that pin 6 is a key and should be removed.Thank you,Brett
Thanks a lot man... made my day there.

From the FAQ:
Q: What is TDIS used for?
A: XDS emulators can use this pin to detect when the target is disconnected from the emulator. It is usually a pull-up in the emulator and GND on the target. The emulator senses the removal of GND.
From what I see, the TDIS is grounded rather that pulled up.
Do I permanently set the TDIS pin to ground for the DSP? Is there any special importance to make it floating or connected to the TDI of the emulator?
Thanks a lot for your time.
Abdul,I'm no expert, but it sounds (from the FAQ) like the target board should ground TDIS. The schematic I sent is for the target board (which has the C2000 MCU on it). So it shows TDIS tied to ground.Thank you,Brett
aaaah that cleared that one. I thought the graphic is for the emulator itself.
Thanks a lot man.
I downloaded the ControlSUITE anyway, and installed it. But the result is that there's no controlSUITE program for me to run! Is it integrated with CCS? Mine's a microcontroller edition of CCS v4.
Thanks for ya time,
Halim,controlSUITE is not really integrated with CCSv4. However, if you look in Start->All Programs->Texas Instruments->controlSUITEthere is an application which will allow you to browse the software suite in a graphical manner.In general though, controlSUITE is a set of files useful for development with C2000. If you installed controlSUITE with the default install path, all files will all be found at:C:\TI\controlSUITE\Thank you,Brett
thanks brett. I am a bit confused with the systems nowadays.
I'm only one step away from fabricating my first F28027 PCB, but first just a couple of quick questions:
1. The EMU0/EMU1 pins are not connected to any pins of the F28027, I assume? I can't find any designation on it. And the FAQ doesn't seem to address anything regarding it, except mentioning that it's not supported in XDS100v3 (but mine's v2 anyway). What do I do to the pins? Do I pull them down/up?
2. I'm going to re-adapt the emulator pins into a minimum number anyway, so will I need the EMU0/1 pins in future?
I've just made a board using a 28069 and I had to do the following on the JTAG header:
1) to TMS on DSP
2) to TRST on DSP, with 2k2 pull-up to 3V3
3) to TDI on DSP
4) to ground
5) to 3v3
6) no pin
7) to TDO on DSP
8) to ground
9) join to 11 (i.e. a TCK loopback)
10) to ground
11) to TCK on DSP (and also to pin 9)
12) to ground
13) to 3V3 via 4k7 pull-up
14) to 3V3 via 4k7 pull-up
I remember that I needed most, maybe even all of the above to get it to work with the programmer (an XDS 510). Sorry I can't say for sure, but the above does work for me.
yeah, I also just read the datasheet:
NOTEThe 2802x devices do not have EMU0/EMU1 pins. For designs that have a JTAG Headeron-board, the EMU0/EMU1 pins on the header must be tied to VDDIO through a 4.7-kΩ(typical) resistor.
So you're right.
