Each connector has a specific arrangement of the signal pins, which are grouped together in categories related to their functionalities and to their belonging to particular units of the Zynq UltrascaleUltraScale+ MPSoC like I/O - banks, interfaces and Gigabit transceivers
or to the on-board peripherals.

...

...

JTAG access is provided through the MPSoC's PS configuration bank 503 with bank voltage ' PS_1V8'.

...

The Xilinx Zynq UltraScale+ MPSoC's PS configuration bank 503 control signal pins are accessible through B2B - connector J2.

For further information about the particular control signals and how to use and evaluate them, refer to the  Xilinx Zynq UltraScale+ MPSoC TRM and UltraScale Architecture Configuration - User Guide.

...

Quad SPI Flash memory ICs U7 and U17 are connected to the Zynq MPSoC PS QSPI0 interface via PS MIO bank 500, pins MIO0 ... MIO5 and MIO7 ... MIO12.

Boot Process

The boot source device and mode of the Zynq UltraScale+ MPSoC can be selected via 4 dedicated pins , which generate a 4-bit code to select the boot mode. The pins are accessible on B2B connector J2:

...

Table 8: Boot mode pins on B2B connector J2.

Following boot modes are possible on the TE0808 UltraScale+ module by generating the corresponding 4-bit code by the pins ' PS_MODE0 ' ... ' PS_MODE3 ' (little-endian alignment):
