TMS320F28035: TMS320F28035

Enzo Ternavasio
Expert 1065 points
Part Number: TMS320F28035


Tool/software:

With MSP430F51 controller I used only a 5 pin connector for debugging and programming.

With TMS320F28035 i see, at pg. 24 of its data sheet,  a connection, figure 5.4, of 14 pins.

Some pins indicated do not correspond to: XDS110 Depug Probe User Guide

figure 2, pg. 9

I am very confused.

    Hi Enzo,

    C2000 can be used with either the TI 20-pin standard (which you see in the XDS user guide) or the TI 14-pin standard. XDS110 Debug probe comes with an adapter that adapts the 14-pin standard to the 20-pin standard so you can use either. You can see more information about the standards here: https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html

    Hy Peter.

    You are suggesting me a documentation for TMS320C6000 DSP; I have the: XDS110 Debug Probe User's Guide

    and I think it is more appropriate. In that paper there is no schematic of 14 pin larger header, though it is present in the box a hardware for conversion 20-->14.

    14 header is needed, to evoid the 20 pin mini connector, whose thin pins give no reliability.

    I have to say that a signal listed on 20 pin connector of XDS110 is not explained: nRESET; it disappears on 14 pin connector.

    In your paper suggested, the schematic of 14 pins connector fortunately exists.

    Based on that informations, I see that no longer i will use the simple 5 pin JTAG of MSP430, but I will use a 14 pin connector.

    Is it correct?

    Hi Enzo,

    The link I referenced also applies to the C2000 family of MCUs. It would be helpful to understand the hardware you are working with. Is it a controlCARD with HSEC docking station? In this instance you would want to conform to TI JTAG pin, either 14 or 20 pin depending on hardware version of docking station. 

    5-pin JTAG is not one of our standardized layouts, that may only be applicable for custom use case. But 14-pin is universal for TI devices. Like mentioned, the XDS110 debug probe itself should come with all required adapters to connect to 14-pin header.

    For nREST/nRST, this is just an optional signal provided by the debugger, a lot of devices do not need this signal so that is why it is omitted in 14-pin standard

    Regards,

    Peter

    Hy Peter.

    For my purpose, I will use a 10 pin Canon header on my prototype, smaller than a 14 pin.

    I see that 10 pins collect all signals, beeng GND redoundant 5 times.

    Thansk for your help, Enzo
