content: HiI bought this device from RS in the UK believing it was a TI part. I have hardly used it and it has failed during a firmware probe check. So now I am in the position of having a bricked XDS200. RS wont help me as its just over a year old. The actual manufacture is Blackhawk-Dsp / Corelis and they are blanking me. And because I am retired (no company clout anymore) I cannot contact Texas Instruments even via E2E. Its a TI reference design.I am at a loss what to do. Just proves that RS are box shifters and quite honestly I wish I had bought from AliExpressAny suggestions?

content: Nice suggestion but the serial number is logged.I really cannot understand how RS get away with huge mark ups yet provide zilch technical support. They should have a workshop and the ability to re flash kit as a minimum.Anyone else feel powerless being outwith a corporate structure?

content: RS logs the serial numbers when they sell them? That would be a surprise.Can the case be swapped over without breaking any seals.

content: As part of my support request to RS the serial number was logged. All that I am asking of RS is to put pressure on Blackhawk DSP for a remedy but they dont want to know

content: Yes but you'd be opening a new case for the new probe, which would have no SN associated with it.Anyway, you can pursue the legal avenue but it might be more work and take longer:https://www.citizensadvice.org.uk/consumer/somethings-gone-wrong-with-a-purchase/return-faulty-goods/

content: If you have another XDS JTAG debug probe, you can try to re-flash it by following the procedure shown in the URL below - despite it mentions the onboard/embedded Debug Probes, it works for the standalone probe as well.https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds200.html#re-flash-the-firmware-of-onboard-xds200-units-You will have to open your probe for that to work.

content: Its beyond reflashing via USB. I have opened the device including the seals. Its disappointing to find a completely non standard JTAG ? connector. Its a AM1802 inside. Because if I knew the pinout I could use another emulator and reflash. The problems all began when I discovered it didnt work via a usb hub so I was using TI software to probe it. My last resort would be taking a guess on the JTAG pins.

content: Read all the links on the reference I sent. One of them has the pinout of the edge connector used by the XDS200's PCB (IIRC), which is similar to the Mezzanine card used in some of the EVMs.

content: Hiappreciate the links but that is for another device. I have the TMDSEMU200-U which has a 16 way samtec connector nothing like any JTAG I have seen before.I now have a chink of light I have managed to open a support case with TI so hopefully that will bear fruit. That post reflectson the hub difficulties that I experienced. It is certainly not fit for purpose and and that price a scam.Thanks and regards

content: Ok, if you see a connector inside, it is probably the cTI 20-pin connector, a ~15 year old standard for TI processors.Its pinout (and several others that comprise the TI and ARM JTAG connectors) is shown at:https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_jtag_connectors.html

content: HiIts certainly not a standard JTAG connector as I have all the adapters for Segger /TI / ARM / SWD and they are 10w 20w and 14w whereas this is a 16w
