On board JTAG connector[edit | edit source]
The Zynq-7000 family of AP SoC devices provides debug access via a standard JTAG (IEEE 1149.1) debug interface. This JTAG port grants access to the device chain composed of both the CPU core and the FPGA part.
JTAG signals are connected to the pinout connector (J2) on BORA.
