2.11.9 JTAG

The AM263Px Control Card includes an XDS110 class on-board emulator. The control card also has the option to map the JTAG signals from the AM263Px SoC to the HSEC connector.

A DIP switch (SW1) is used to drive the select line of a 1:2 mux (SN74CB3Q3257PWR) that determines the pathing of the AM263Px SoC JTAG signals.

The Control Card 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 emulation circuit so that the connection to the emulator is not lost when power to the Control Card is removed.

The XDS110 controls two power status LED's. For more information refer to Section 2.2.2.
