Other Parts Discussed in Thread: UNIFLASH, TMS570LS1227, TMS570LS1224

Hello,

I'm trying to connect to LAUNCHXL2-TMS57012 via UNIFLASH with no luck.

Configured Device : Texas Instruments XDS110 USB Debug Probe keyboard_arrow_right TMS570LS1227

when I try to Read Memory, it just writes "Loading" forever...

What am I doint wrong?

Many Thanks

Andre

    Hello Andre,

    1. Choose your device: TMS570LS1224

    2. Choose your connection: XDS110 USB Debug Probe

    3. Start

    4. Memory tab->Read Target Device: click on "ReadTargetDevice", it will configure the debugger, then read the memory

    Or you can use CCS7.x to verify the JTAG connection:

    View_>Target Configuration->Under Define (Projects) ->Right click, New Target Configuration

    Target Configuration: select XDS110, and TMS570LS1224, then Save Configuration

    Click Test Connection

    You will see a message window which shows the connection status.

    If you are talking about UNIFLASH 4.x, I can't find there "Connection" item.
    I have installed UNIFLASH 3.x, and it worked well.
    Thank you

    Hello,

    I also want to know why I can't use JTAG pins from this PCB in order to read/write onboard chip.

    If I desolder CPU and move it to the other board, as I connect TCK pin, board does not load. Why this happens?

    If I order full verion of XDS programmer it would work or no in this case?

    Many thanks.

    Hi,

    Is anybody here?

    Can you tell me minimum requirements of TMS570 connection (power, ground etc.) in order to make JTAG work.

    Thanks

    Hello Zend,

    I am unable to tell what you are attempting to do by the description you have provided. Are you stating that you have taken the MCU off of the Launchpad and moved it to a custom board and are now attempting to use the Launchpad XDS110 as an emulator for your custom board? If this is the case, this is not a recommended usage of the launch pad.

    To actively debug or program the device you need to have the full JTAG connections which include nTRST, TCK, RTCK, TDI, TDO, TMS, GND etc. The device itself needs to be powered with the appropriate 3.3V and 1.2V power rails and a clock source needs to be provided on OSCIN.
