Block Diagram
The block diagram shown below gives an overview over the Zynq SSE reference design: Within the Zynq Programmable Logic (PL) the MLE storage micro-architecture instantiates the DMA and the SATA Host Controller IP blocks. The storage micro-architecture itself interfaces with the Zynq Processing System (PS) via the high-performance AXI HP0 slave port. The ARM A9 in the PS runs Xilinx PetaLinux and the SATA Linux kernel driver.Implementation

Step by Step Instructions
Hardware needed:
• Avnet Mini ITX Z045 Board (including Power supply) Link- Micro USB Cable for USB Console
- Supported SSD (for Example Samsung 840)
- Power Supply for SSD
- Micro SD Card (2 GB or bigger)
- Ethernet Cable to connect Host PC and Avnet ITX board
Software Assembly:
1. Format the SD Card using FAT32 File system2. Put image.ub and BOOT.bin into the root directory of the SD Card
Hardware Assembly:
- Insert the SD Card into the Avnet Mini ITX board’s SD Slot
- Connect the micro USB cable to the UART port o
- Connect the Ethernet port of the host pc to the ethernet port of the Avnet MINI ITX
- Connect the SSD to the SATA connector on the Avnet Mini ITX board using the SATA Cable.
- Connect the SSD to power
- Switch the Avnet Mini ITX board’s SW7 to SD Boot mode (as shown in picture)
- Connect the Avnet Mini ITX board to the Power Supply
Startup:
Connect to the Avnet Board using RS232
- Switch on the Avnet Mini ITX board
- On the PC open a Serial Terminal on the new serial port using the settings 115200 Baud 8N1
- Observe the Linux System booting
- After some time you should see a screen similar to the screenshot in the Expected Results.
- Login using
Login:root
Password: root
Connect to the Avnet Board using FTP
- configure the ethernet port on the host PC to have an IP address of 10.89.231.1 and a subnet mask of 255.255.255.0
It is crucial to configure the Host PC that way so that it can connect to the ZYNQ board - The ZYNQ-board has an pre-supplied IP of 10.89.231.200
- now connect to the ZYNQ-board which has the IP of 10.89.231.200 using an FTP program and start transferring data to it
$ ftp 10.89.231.200 Connected to 10.89.231.200. 220 Operation successful Name (10.89.231.200:christian): root 230 Operation successful Remote system type is UNIX. Using binary mode to transfer files. ftp>
LED Description
Status LEDs can be found next to the PCIe connector. The associated meanings can be seen in the following table and in the Image below.Figure 1: Location of the User LEDs on the Avnet Mini ITX Board
Expected Results
As a result you should be having a running Linux system on the Zynq board. The UART Console output should be similar to the screenshot below.Also you will have file-system access to the attached SSD using FTP, and by this evaluate and test the Zynq Sata Storage extension.
The Evaluation Reference Design (ERD) of the Zynq SSE comprises a hardware license management which allows to run full SATA functionality for up to 12 hours after power-up. After approximately 12 hours the evaluation expires, which is indicated by illuminating the LED ’timeout’. You will also notice that the Linux kernel driver informs you of having lost the SATA link to the SSD/HDD.
D7 | Timeout LED, indicates the Timeout of the IP core. |
D6 | Gen3 Link, indicates 6 GBit/s connection |
D5 | Gen2 Link, indicates 3 GBit/s connection |
D4 | Linkup and Activity, Led will light up on Linkup and will go dark during data transfers |
