TMDSEMU560V2STM-U: 4 of 5 debuggers not working from the beginning - model TMDSEMU560V2STM-U

Part Number: TMDSEMU560V2STM-U
Other Parts Discussed in Thread: J721EXENETXPANEVM,

Hello TI Team,

I am reporting an issue with 4 out of the 5 units purchased from DIGIKEY distribution - model TMDSEMU560V2STM-U.
Initially, we purchased 3 units, and immediately 2 of them showed errors as shown in the attached screenshots.
After consulting with DIGIKEY distribution support, we returned the 2 non-functional units and, while waiting for the correction, ordered the last 2 units from the distributor's stock.
It turns out that both of these units also do not work from the beginning.
We kindly ask for verification of our report and approval for the replacement with 2 new functioning units.
Currently, we only have one unit that has been working since the beginning, and we need a total of 3 units.

Both XDS560v2 debuggers (TMDSEMU560V2STM-U) were checked in each case with, among others, the Texas Instruments J721EXENETXPANEVM and J784S4XG01EVM EVMs.
We own several TMDSEMU560V2STM-U debuggers purchased 2023 and they have not caused any problems so far.

Symptoms of defect:

SN: SB47416 - Issue description: The product is not recognized by Windows each time (message - "No USB"), the device does not fully boot even after hours.
SN: SB47243 - Issue description: The product can boot, but cannot be communicated with. Dozens of attempts have been made without success.
SN: SB47208 - Issue description: The product can boot, but cannot be communicated with.
SN: SB47264 - Issue description: The product can boot, but cannot be communicated with.

Please accept the supply of two new good working debuggers.

    

Best regards,

Piotr Ochalik

  • Hello,

    SN: SB47416 - Issue description: The product is not recognized by Windows each time (message - "No USB"), the device does not fully boot even after hours.

    Sounds like a defect with the probe itself.

    For the others with the cable break error, basically the debugger can communicate with the probe but the probe cannot communicate with the device due to some hardware connection error from the probe to the board/device.

    For more details, see the "Cable break" error in the below document:

    https://dev.ti.com/tirex/explore/node?node=A__ANoamrIZPWD2-6T-NDDWGg__ccs_devtools__FUz-xrs__LATEST

    Since you have some good probes, did you confirm that you have a board that does work with one of the "good" probes and that the same board fails with one of the "bad" probes? If so, then you know the issue is not related to the board at all and it could be the ribbon cable from the probe that then connects to the jtag header of the board. 

    Thanks

  • Hello Ki,

    Thank you for your quick response.

    Each of the listed products (serial numbers) was repeatedly tested by the Motorola Solutions laboratory.
    In 100% of the cases, there is no communication between the debugger and the EVM.
    The probe has two cables -- a mini USB, which connects to the PC, and a ribbon cable, which connects to the EVM. The ribbon cable is connected to the sensor, and the sensor casing is factory-sealed.
    I do not quite understand what you mean by writing such a sentence, I quote: "If so, then you know the issue is not related to the board at all and it could be the ribbon cable from the probe that then connects to the JTAG header of the board."
    We purchased sensors that do not work (4 of 5 units).
    The ribbon cable is an integral part and there is no external access to change anything with this cable.
    If there is an internal connection problem inside the casing, it should be detected during production, not by the customer.
    Should the customers of these products become beta-testers?
    As a customer, we expect the purchased product to be fully functional and operational.
    Any potential manufacturing defects should be found at the early stages of production.

    According to the picture, the ribbon cable is permanently attached to the device, there is no possibility to detach the cable.
    The products being claimed are in perfect condition. The plug and the cable itself are in perfect condition, not mechanically damaged.
    The debugger casing is closed and there is no possibility to open it.
    A product costing around 1000 USD per unit should meet the expected quality standards.

    Please send us your consent to replace the products with working ones.

    Kind regards,

    Piotr Ochalik

  • Please send us your consent to replace the products with working ones.

    I personally cannot provide this consent. I will notify the group responsible for this product for further support.

    Thanks

    Please contact the vendor (in this case - DIGIKEY) regarding a return.

  • Thank you, Ki.

    We have sent the products to the distributor for correction.
    We need two new working units, but I see on TI.com that the TMDSEMU560V2STM-U is unavailable. The same situation is in the distributions.
    Could you please inform us if the two products below are identical?
    Are there any differences between them?
    We care about compatibility with the Texas Instruments products EVM J721EXENETXPANEVM and J784S4XG01EVM:

    Thank you, Ki, and best regards,

  • Could you please inform us if the two products below are identical?

    They look like the same product to me. 

    BH-USB-560V2 is Blackhawk's product number

    TMDSEMU560V2STM-U is TI's product number of Blackhawk's BH-USB-560V2

    Some of the description for the latter is outdated. I can't explain why there is a price difference. I would contact the distributor for clarification.

  • Thanks Ki and we look forward to your comments on the comparison between the two models.

    As I mentioned earlier, please contact the distributor or the owner of that webpage you referenced. I can't explain the differences.

  • Hi Ki,

    Please let me know what will be the disposition of returned defective items.

    We are now in the process of creating a return authorization requested by the digikey to process the RMA. We need the disposition of the defective items. Do we need to return the 4 defective items to TI?

    I have started a discussion with some people regarding the return.

    Piotr - Not sure if you still have any of the bad probes but one thing I did want to check with you if the probes with any issues are rev G. If they are rev G, just want to double check that you followed Blackhawk instructions regarding the dtc_top.jbc file. The instructions come in the box with the XDS560v2 probe:

  • Hi Ki,

    Just need some clarification here, if in case we identified that the probes are indeed received defective, the return process should be processed by Digikey right?

    Cordially,

    Please disregard this message. I confirmed that it only applies to the TMDSEMU560v2STM-UE (the one with additional ethernet capability). It does NOT apply the TMDSEMU560v2STM-U (USB based only).

    I actually do not know what the official return policy is for this. I don't have much visibility into it.

  • Hi Ki,

    Thanks! we're waiting for the final confirmation that the 4 boards are indeed received defective. Hopefully we can received that confirmation the soonest.
