2834x 168pin experimenter kit connector & schematics update

Hi  everybody

please any news ?

thank you

bye

Carlo,

Attached is the most recent version of the 168-pin docking station.  Unfortunately, this set of docking stations did not match up with the DIM168 Delfino controlCARD; particularly, the issue was with pin 107.  This pin/trace will need to be cut for the board to work.


Thank you,
Brett

Brett,

The schematics you have attached show a DIMM168 USB experimenters board using an FT2232D (I'm assuming this is used to implement XDS100 emulation).  I thought the the 168-pin docking station didn't come with the USB emulator  because they "require an external JTAG emulator to keep up with the C2834x’s high performance".  Are the drawings you attached for a new version that is not released yet?  Can the FT2232H shown in this schematic (or the FT2232D used on the other USB docking stations) be used to successfully implement an XDS100 emulator in combination with the TMDXCNCD28346-168 control card following this procedure.  It would be nice to use built in USB emulation for a project I'm working on.

Thanks,

Jon

Jonathon,

About 2-6 months ago we released a new revision of the DIM168 Experimenter's board which works in conjunction with the C2834x DIM168 controlCARD.  This was done so that the controlCARD could work with an onboard xds100v2 emulator.  The xds100v2 emulator is a step-up from the earlier xds100v1 emulator (which we've been using on many C2000 kits) and has a faster data rate which would make the debugging process more workable. 

Most of the other controlCARD's Experimenter Kits come with a board which has an onboard xds100v1 emulator.  The procedure you linked gives the process to get the xds100v1 emulator working.  The process for xds100v2 is similar but uses a different .ept file. 

The xds100v1 (FT2232D) or xds100v2 (FT2232H) can be used with the C2834x devices although I would recommend using the xds100v2 because of the reasons mentioned above.

See the following wiki article for more information:

Thank you,

Brett,

I have a couple more questions about the integration of the XDS100v2 with the DIM168 control card.

1.  The DIM168 USB schematics you attached do not include the CPLD from the XDS100v2 reference design (from the Wiki page you linked to).  If I were to build my own board to interface to the control card which design should I follow (with or without the CPLD)? 

2.  Would the .ept file needed to program the device be different than the one included with the XDS100v2  reference design if I omitted the CPLD?

On a side note, I thought is was awesome that the XDS100v2 reference design is provided as a Kicad project.  It would be even more awesome if the hardware development files in controlSUITE followed the same format.  ; )

Thanks,

Jon

Jonathon,

To be honest I'm not really an expert in the xds100v2 hardware.  I believe the CPLD was added as a minor revision to the original xds100v2 design in order to support adaptive clocking.  Which I believe is needed to fully support emulation on ARM parts that TI has.  If you want to be safe (which may be the best option), you can certainly go with the full xds100v2 design from the wiki site and do well.

In-house we've used the DIM168's xds100v2 design and things have worked with C2000 devices, so you can also use that as well.


Thank you,
Brett
