AM263P2: Flashing issue

Venkata Rami Reddy Vempati

Part Number: AM263P2
Other Parts Discussed in Thread: XDS110ISO-EVM, LP-XDS110

Hi Team

Im facing an issue while flashing the code. The debugger LED is OFF, although the MCU appears to be functioning correctly and all supply voltages have been verified.
Could you please help me resolve this issue?

    Hi Venkata,

    I see you're getting Error -260 when trying to connect your XDS110 debugger to the AM263P2. The error message points to several possible causes, and the fact that your MCU is functioning and voltages check out is good—this looks like a debugger communication issue rather than a hardware fault.

    Just to confirm, are you using a TI EVM or is this custom hardware?

    Here's what I'd recommend checking:

    1. USB connection & cable – Verify the USB cable is firmly seated on both ends and try a different USB port (preferably a direct port on your computer, not a hub). A faulty or loose cable is a common culprit.

    2. XDS110 firmware & serial number – As the error suggests, run the firmware update utility:

      • Navigate to <CCS_install>/ccs_base/common/uscif/xds110/
      • Use the xdsdfu utility to check and update the firmware and serial number
      • Refer to the XDS110SupportReadMe.pdf in that same directory for step-by-step instructions

    3. Debugger LED status – The LED being off is unusual. After updating firmware, check if the LED comes back on. This would indicate the debugger wasn't being recognized by your system.

    • Which XDS110 variant are you using? (e.g., XDS110ISO-EVM, LP-XDS110, or another?)
    • Have you already attempted the firmware update with xdsdfu, or is this your first time troubleshooting this?
    • Are you able to see the debugger appear in your system's USB device list (Device Manager on Windows, System Information on Mac)?

    Best Regards,

    Zackary Fleenor
