2.14 JTAG

The AM261x LaunchPad includes an XDS110 class onboard emulator. The LaunchPad includes all circuitry needed for XDS110 emulation. The emulator uses a USB 2.0 micro-b connector to interface the USB 2.0 signals that are created from the UART-USB bridge. The VBUS power from the connector is used to power the emulator circuit so that the connection to the emulator is not lost when power to the LaunchPad is removed. For more information on the XDS110 and the UART-USB bridge refer to UART

The XDS110 controls two power status LEDs. For more information on the Power Status LEDs refer to Power Status LEDs
