System Controller I/O Pins
Special purpose pins are connected to System Controller CPLD and have following default configuration:
Pin Name | Mode | Function | Default Configuration |
---|---|---|---|
RESIN | Input | Reset input | Active low reset input, default mapping forces POR_B reset to Zynq PS. |
PGOOD | Output | Power good | Active high when all on-module power supplies are working properly. |
MODE | Input | Boot mode | Force low for boot from the SD card. Latched at power-on only, not during soft reset! |
EN1 | Input | Power enable | High enables the DC-DC converters and on-board supplies. Not used if NOSEQ is high. |
NOSEQ | Input | Power sequencing | Forces the 1.0V and 1.8V DC-DC converters always ON when high. |
JTAGMODE | Input | JTAG select | Keep low for FPGA JTAG access. |

Ethernet Interface
The Marvell Alaska 88E1512 (U8) is a physical layer device containing a single Gigabit Ethernet transceiver and three separate major electrical interfaces: MDI interface to copper cable, SERDES/SGMII interface and RGMII interface. RGMII interface is connected to the Zynq SoC PS bank 501 MIO pins, see section Default PS MIO Pin Mapping.
SGMII (SFP copper or fiber) pins are routed to the B2B connector JM3 and MDI pins are routed to the B2B connector JM1 (see table below).
