3.2 JTAG Interface
3.2.1 On-board Interface
The JTAG boundary scan chain can be accessed via a standard header (J2).
This allows the connection of the Xilinx JTAG cable for FPGA debug and QSPI Flash programming via the Xilinx
toolchain.
The JTAG chain starts on the config FMC board and through the Base board, passing through the FPGA, the
LPC FMC (if fitted) and the FMC+ (if fitted).

3.2.2 JTAG Voltages
The Vcc supply provided to the JTAG cable on the config header is +3.3V and is protected by a poly fuse rated at
375mA.
The voltage level of the JTAG chain on the ADM-SDEV-BASE board is set to the config FMC adjustable voltage
FMC2_VIO.
