RealView Platform Baseboard for ARM1176JZF-S User Guide: 2.3. Connecting JTAG, Trace, and configuration equipment

2.3. Connecting JTAG, Trace, and configuration equipment

You can use JTAG debugging equipment and the JTAG connector to:

connect a debugger to the ARM1176JZF-S core and download programs to memory and debug them
program new configuration images into the configuration flash, FPGA, and PLDs on the board. (You cannot program the normal flash from configuration mode.)

The JTAG connector is shown in Figure 2.2.

Figure 2.2. JTAG, Trace, and config connectors

The debug mode is selected by default and the JTAG port can be used to debug applications running on the processor.

If the CONFIG switch is ON, the JTAG or USB config port can be used to load FPGA images. For more details on JTAG debugging see JTAG debug port and USB config port support.
