    Trouble programming TAG4

      I received my new TAG4 last week, but so far I am unable to program it. I have done the following:

      1. Upgraded to SDK 2.2.3

      2. Set SW4 to VUSB and SW5 to VREG

      3. Set all SW6, SW8 and SW9 DIP switches to OFF, except

         a. SW6: 2 and 4 are ON

         b. SW8: 1, 3 and 5 are ON

      4. Left all the jumpers unconnected

      5. Connected the USB cable and saw two ports appear in device manager:

         - Silicon Labs Dual CP210x USB to UART Bridge: Enhanced COM Port (COM4)

         - Silicon Labs Dual CP210x USB to UART Bridge: Standard COM Port (COM3)

      6. Picked "watch-BCM920737TAG_Q32 download" on the list of targets and hit Build


      Result: download fails - see output below. Unlike my TAG3, the TAG4 doesn't flash any LEDs when connected or when attempting to download the app.
