Recommended Accessories

TesKit is a "Test Fixture" for testing TE0808, most I/O pins are looped back for I/O Connector connectivity testing. For additional testing an LVDS oscillator is providing known clock to GT Reference Clock. SMA Connectors are provided on PL and on PS Connected GT lanes. Connector is provided for direct connection to SiLabs ClockBuilder Pro Field Programmer for Si5345 Programming.

NOTE: Kit Content may be different, depending on customer agreements. Positions 1 to 3 are always included.

 Supported Bootmodes are SPI and JTAG.

Getting Started

TestKits are pre-assembled and pre-flashed with initial Flash image, they start up as soon as power (3.3V) is applied.

WARNING: There is no over-voltage protection on TEBT0808, proper power supply must be used!

Power would be around 3W if the ZU+ does not boot (DDR4 not active).  With Linux booted (or hello world from DDR4), the power consumption goes up to some 5W. If the junction temperature goes higher, then the power consumption goes up to 6-7W.

Startup procedure

  1. Connect mini-USB Cable to PC
  2. Start terminal 115200 Baud
  3. Connect 3.3V Supply to 2mm Banana Connectors
  4. Turn on power

Depending on initial Flash content either Hello appears, or then Linux does boot.

To restart the boot process press the small push-button on TE0790, it is wired to TE0808 Reset.

GT Transceiver connections and loopbacks.

PL I/O has on-board internal loopback an all pins for connectivity testing.


UART is available on MIO68, MIO69 via the supplied TE0790 USB Module. TE0808 and TE0803 board parts do not support this settings. They must be changed manually.

SPI Flash Programming

Flash programming is supported from SDK GUI, fsbl.elf that is needed is provided in common download area.

NOTE: Boot mode must be set to JTAG before starting Flash Programming.

Reference and Test Designs

Please check Project Delivery - AMD devices first.

Hello World

This works out of the box with Vivado/SDK 2016.1, if you only have EVAL license for ZU+ then it is necessary to export HDF without bitstream.

NOTE: 2016.1 Bootgen seems to have small bug, automatically generated BIF file has bitstream partition set to PS as destination device what results in BOOT.BIN that does not load correctly. Make sure it is set to PL. This problem has been fixed in 2016.2


Support in Petalinux 2016.x for ZU+ MPSoC is fully integrated. Vivado HSI flow works, all settings from Vivado Design are imported to SDK and Petalinux to generate a working system with all required software components.

Important: BL31.ELF is needed or Linux would fail with kernel panic. PMU Fimware is not absolutely necessary, without it there would be warnings during Linux boot.

Note: if there are no network drivers installed, then linux boot does stop on "Configuring network interfaces..." as workaround special "disable network" application can be installed into petalinux to allow booting with no network.


If Si5345 is not programmed then there is only 1 GT Clock available, from 125MHz oscillator on TEBT0808, it does clock B228 CLK0 input, with this clock up to 12 GT can be tested, including the GT that has SMA connectors.
