CCS/TMDSCNCD28035ISO: TMDSCNCD28035ISO

Part Number: TMDSCNCD28035ISO
Other Parts Discussed in Thread: TMDSCNCD28035, TMS320F28027F

Tool/software: Code Composer Studio

Hi,

I have recently purchased the TMDSCNCD28035ISO control card through Mouser. When I am trying to program it through CCS studio ( through Simulink code generation)  I get the following meassage

"SEVERE: C28xx: Error connecting to the target: (Error -1135 @ 0x0) The debug probe reported an error. Confirm debug probe configuration and connections, reset the debug probe, and retry the operation. (Emulation package 6.0.407.3)"

When I am trying to program any other control card of texas instruments ( ex. TMS320F28027F, TMDSCNCD28035 R1.2 ETC.) with the same cable through the same port of my laptop using always the correct microcontroller target I am able to perfectly program the cards. 

Furthermore I received the TMDSCNCD28035ISO control card with some external wire connections as shown in the attached pictures which I believe is not acceptable for a new product (blue cable in the picture) .

Looking forward to your feedback.

Best regards,

Nikitas

    Nikitas,

    Thanks for reaching out to the E2E forum, and thanks for the detail of the issue and pictures.  Can you confirm which LEDs are lit when you try to connect to the board(LD1/2/3/4).  LD1 = Board Power, LD4 = USB mini/emulator power(LD2/3 are GPIO31/34)

    Since this is an isolated design the power for the MCU is not sourced through the mini USB header, but through the bottom DIMM  connector from the docking station.  That will need to be connected and supplied with 5V to power the control card.

    If all of the above is done, and you still can't connect, please post a follow up.

    BTW, I've tried to capture common JTAG connection issues in an app note here: http://www.ti.com/lit/an/spracf0/spracf0.pdf .  The above process is covered, but for the sake of time I wanted to root cause this given this is the ISO version.  If we have further issues the app note should be helpful as well.

    Finally, I will look into the blue wire(s) you've shown.  Typically this is done if we find an issue with a board, and have built a significant qty so that we can ship evaluation modules without supply interruption.  While they do visually stick out, the board should behave in the correct manner electrically to the spec/schematic.

    Best,
    Matthew

    Hi Matthew,

    That resolved my problem. Thank you!

    Hi Nikitas,

    Matt is correct.  Some builds of this TMDSCNCD28035ISO contain blue wires to fix some problems on the blank PCBs. 

    With the blue wires, these controlCARDs will work as designed.


    Thank you,
    Brett
