TMS320F2800157: Debug with LP-XDS110

MSP432E401Y: LP‑XDS110ET

Part Number: MSP432E401Y
Other Parts Discussed in Thread: LP-XDS110ET, MSPM0G3507, UNIFLASH, TMS320F28069, TMDSEMU200-U, ALGO-3P-UISP1-TI, TMDSEMU110-U, ENERGYTRACE

Hello I am using the LP-XDS110ET in order to flash and debug the controller tms320f28069upzps through the XDS110 output connector but it is not working at all. I have no idea why

Best regards

    Hello Ali Mousa,

    A few things to check first:

    • Is your LP-XDS110ET detected by other programs correctly?
    • Are you using a 10 - pin JTAG connector?
    • Is the green LED light powered ON on (solid green) the XDS110? 
    • Do you get any errors when trying to flash/debug the tms320?
    • Is the TMS320 using a custom PCB, and did you already get the PCB reviewed? 

    Thanks,
    Alex F

    Hello Alex,
    thank you for your response.


    Regarding the first question: the LP‑XDS110ET is working correctly, as I was able to flash an MSPM0G3507 controller using both Code Composer Studio and UniFlash.
    Additionally, I was able to flash the TMS320F28069UPZPS microcontroller using the XDS110 JTAG Debug Probe, and I successfully flashed the LP‑MSPM0G3507 using both the LP‑XDS110ET and the XDS110 JTAG Debug Probe.

    Does the RST pin of the TMS320F28069UPZPS need to remain held low during the entire flashing process?
    Thanks in advance for your support.

    Best regards,
    Ali

    Thanks for the confirmation, so it looks like there is a proper connection with the JTAG cable to the XDS110, and that the TMS320 can be flashed!

    I unfortunately am not familiar on this specific device, since we can flash the device, we could use a logic analyzer to measure the state of the pin during the flashing process to see when it goes high or low. 

    I also wanted to ask are you flashing it different than the JTAG when the error occurs? Additionally, from experience with other devices we should check the SWD pins, as if they are connected to some other peripheral and are potentially active (changing state) during debugging/flashing it would cause an error. 

    Thanks,

    Hello Alex,

    I am flashing the controller using JTAG.

    Does the LP‑XDS110ET support microcontrollers that are not based on the ARM architecture?

    Thanks,
    Ali

    Hello Ali,

    Looking at the XDS110ET device page the C2000 is not directly mentioned as a supported device. Looking at the TMS320F28069 product page you seem to use the ALGO-3P-UISP1-TI programmer or the TMDSEMU200-U (XDS200) USB debug probe.

    Hello Alex,


    Could you please provide us with the schematic for the following debug probe:


    TMDSEMU110‑U (XDS110 JTAG Debug Probe) – www.ti.com/.../TMDSEMU110-U?
    I would like to understand the differences between the XDS110 JTAG Debug Probe and the LP‑XDS110ET

    Thanks,
    Ali

    Hello Ali,

    Quoting another TIer from another thread:
    "Unfortunately the XDS110 standalone pod (TMDSEMU110-U) design files are not public. As you said, reduced versions are available embedded in Launchpads and development kits."

    "Although the changes to the standalone XDS110 are much larger (mostly due to the auxiliary and expansion connectors), the fundamental functions can be found in the various implementations: the MSP432 is the most complete as it feaures EnergyTrace." 

    -The standalone XDS110 has an "expansion interface", also looking at the XDS110 Debug Probe documentation the C2000 MCUs are supported.
