Hi Yong,

It should be 2.5mm ID & 5.5mm OD, based on the barrel connector listed in the Docking Station's BOM. 

A compatible supply could then be the: Phihong PSAC05R-050(P)-R-C2 & a Phihong RPBAG.

Note that instead of using an external supply, you can use a USB cable plugged into the Docking Station to provide the 5V power.  If you want to enable your xds200 to be the emulator & remove any chance of contention with the onboard emulator, you can populate J8 on the Docking Station baseboard.

Hopefully this helps!


Thank you,
Brett

Hello, Brett,

   Thank you very much for your email and the part number.

   Yes, I indeed want to use xds200 emulator but I cannot find J8 from the docking station baseboard.  Do you mean to populate J84/J85/J86/J7?  In addition, should I populate R40 - R46 of the F28M35xx controlCard?

   Thanks,

   Yong

Hi Yong,

J8 on the Docking Station is highlighted below.  You can find the schematic & pcb files for this hardware within controlSUITE.




I'll look into your question on the controlCARD's R40-46, shortly.


Thank you,
Brett

Hi Yong,

The schematic for the Controlcard is in the below directory if you have not already found it:

C:\ti\controlSUITE\development_kits\~controlCARDs\CCF28M35xxHWdevPkg_v3\R_PWB_RevD

Yes, you'll need to populate R40 - R46 to connect the F28M35 to the JTAG header on the docking station.

Best,

Kevin

Hello, Brett,

   Thank you for your email and I populate J8 of the Docking Station baseboard and R40-R46 of the F28M3xx controlCard.  I run Test Connection and get following error message,

  In addition, from the link of 

https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/344517?How-to-connect-the-F28M35-controlcard-via-docking-JTAG-

  It looks like even the package has 3 emulators (built-in emulator on controlCard (J20), built-in emulator on Docking Station baseboard JP2, and external emulator on Docking Station baseboard J2), it only makes on board emulator working (J20). To use either emulator JP2 or J2, it needs to remove the isolation chips on the controlCard (U19-U222 and U40) to disable emulator on controlCard J20. Then to populate J8 of Docking Station baseboard to disable emulator JP2 to enable other emulator (could be xds200) J2?  

  Thanks,

Yes, you understand correctly.

Yong Zhou1 said:

When using the XDS200 on the docking station's J2 you don't have the USB cable plugged into the ControlCard J20, correct?

Yong Zhou1 said:

You don't need to remove the isolator chips completely, you can just take the 0 ohm resistors off (R48, 49, 50, 51, 52, 53, and 55)  to remove contention on the signals.

Yong Zhou1 said:

Populating J8 is needed to turn off the JP2 (U2 FTDI chip) JTAG.

Kevin

Hi Yong,

Sorry, didn't mean to click the resolved button. You can ignore or reject that...

Yong Zhou1 said:

However, when testing 2, Test Connection only has 83 % successes repeatedly, is there any comment?

You have J8 not populated in this case, correct? I think J9 on the docking station may also need to be populated.

Yong Zhou1 said:

 My understanding is to make use of 3, I have to remove R48, 49, 50, 51, 52, 53, and 55 and populating J8 which seem not convenient to switch back to 1. 

I believe this is needed to remove any contention on the JTAG signals. Another thing you can try before removing all the resistors listed is setting both switches on SW3 to the off state. That may be enough to remove unwanted contention.

Best,

Kevin

Hello, Kevin,

   Thank you for your suggestion.  To make Test 2 operational, I populated J8 but it is disable the emulator then not working.  Populating J9 had no difference than before with error message "Some of the values were corrupted - 83.3 percent".  Switch off 1 or both 1/2 of SW3 had no differences with the same error message.

   Regards,

   Yong

Hi Yong,

I cannot tell from your last message.  Have you been able to get the system working as you desire (or at least are able to move forward with your evaluation)?

If things are still not working, could you maybe post some pictures of your setup?  Or describe your current setup that is not working?


Thank you,
Brett

Hello, Brett,

  It turned out Kevin partially answered my questions. With the package, I can only make built-in emulator of controlCard working but not other two emulators (one is built-in emulator of Docking Station and other is external emulator) without disable emulator of controlCard by removing some resisters.  Even my goal is to use external emulator and evaluate all of three emulators that available, but I gave it up.

  Thanks,

  Yong
