The package consists of a USB cable, a USB uWire interface board, and a 5 inch cable for connecting to an LMX or LMK evaluation board. All LMK evaluation boards work with this USB uWire interface board. The following LMX evaluation boards may not work with this interface: LMX2350, LMX2352, LMX2353, LMX2354, LMX2364, LMX2470, LMX2471, and LMX2604. The reason for incompatibility is discussed in the section, Using the USB uWire interface board with the “exception” boards, and includes a work-around solution.

The reason these devices do not work is because one of the programming lines: “Clock Bit”, “Data Bit”, or “LE Bit,” is placed on bit position 10, 11, 12, or 14. The programming lines must be placed in one of the lower 8 positions. To correct: 1) Change the violating pin position to one of the lower pin positions which is unused. In the LMX2470 example shown below the “LE Bit” pin can be set to position 1, 3, 4, 5, or 7. 2) Solder a jumper on the evaluation board shorting the new pin position to the old pin position. Once this has been done, the USB uWire interface board will correctly program the evaluation kit in question.

Figure 11 - Selecting "USB" Communication Mode. CodeLoader4 to USB uWire interface board communications Verify USB communications by selecting, “USB” → “Version” from the menu (see Figure 12). Figure 12 - Checking the USB version Figure 13 - USB communication successful, version displayed. If no communication still exists, try... 1. Exiting CodeLoader4. 2. Remove the USB uWire interface board. 3. Reattach the USB uWire interface board, wait for the interface board to be detected. 4. Start CodeLoader4 again. Only one USB uWire interface board may be attached to a single PC at the same time. Known Bugs Plugging in a USB device such as a memory stick may cause CodeLoader 4.1.14 or earlier to crash. 8 IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.
