You can use JTAG debugging equipment and the JTAG connector to:
Connect a debugger to the system processors 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 USB debug port can also be used to download device images. See Procedure for progcards_usb.exe.
The setup for using a JTAG interface with the baseboard is shown in Figure 2.8.
Note
The USB debug port is used to load FPGA and PLD images and cannot be used to debug applications. For more details, see JTAG and USB debug port support.
To use the JTAG interface for debugging, the CONFIG slide switch must be in the OFF position as shown in Figure 2.7.
Note
Some early versions of the Emulator Baseboard have a jumper instead of a switch. Placing the jumper across the connectors is equivalent to the switch being in the ON position.
