==== Specification ====
 
−
 
−
For details of the board hardware, please download the [https://github.com/MeshSr/wiki/blob/master/doc/msr-ons30-hwug.pdf ONetSwitch30 Hardware User Guide].
 
−
== Overview ==
 
−
 
−
A bottom-up approach is recommended when developing on the Xilinx Zynq SoC-based ONetSwitch.<br />
 
−
The figure below from [http://www.wiki.xilinx.com/ Xilinx Wiki] shows a high level block diagram of the Xilinx design flow for Zynq AP SoC.

−
 
−
For any layer or component in this hierarchy, you can either download the pre-built images for quick use, or modify then generate it by yourself in the way described below.
 
−
 
−
==== Get Prepared ====
 
−
 
−
* Prepare the Boot Medium<br />
 
−
Xilinx Zynq SoC offers different types for system booting, on your demand.<br />
 
−
Here in the GitHub for an ONetSwitch, '''the SD boot is chosen as default'''. An FAT partition in the size of 512MB is used for storing the boot and kernel images, while an EXT partition typically larger than 1GB is for the root file system and the applications(e.g. OpenFlow switch software).<br />
 
−
For the detailed how-to, please refer to Xilinx Wiki [http://www.wiki.xilinx.com/Prepare+Boot+Medium Prepare Boot Medium].<br />
 
−
 
−
* Setup a Serial Console<br />
 
−
It is a must to use the USB-UART when running an interactive program on the platform or debugging. Here's a helpful link on Xilinx Wiki [http://www.wiki.xilinx.com/Setup+a+Serial+Console Setup a Serial Console].<br />
 
−
 
−
* Get a Linux Environment<br />
 
−
Software development on ONetSwitch requires a Linux environment for easy cross compilation.<br />
 
−
Ubuntu 12.04 LTS x86_64 may lack some needed 32-bit libraries. This can be fixed by installing <tt>ia32-libs</tt>.<br />
 
−
Ubuntu 14.04 LTS x86_64 may also lack some needed 32-bit libraries. This can be fixed by installing <tt>libc6-i386</tt>.
 
−
* Install Xilinx Tools<br />
 
−
Xilinx Vivado and SDK must be installed for ONetSwitch development. [http://www.xilinx.com/support/download.html Download]<br />
 
−
Notice that, by 2014 Q4, all our projects are developed with Vivado 2013.4.<br />
 
−
When working in a Linux environment, especially for software developers, remember to setup the environment variables for cross compiler and the Vivado/SDK tools.
 
−
 
−
<source lang="bash">export CROSS_COMPILE=arm-xilinx-linux-gnueabi-
 
−
source <path-to-installation>/Vivado/<version>/settings32.sh # OR
 
−
source <path-to-installation>/Vivado/<version>/settings64.sh</source>
 
−
== Use Pre-Built Images ==
 
−
 
−
The pre-built images can be fetched mainly from<br />
 
−
* [https://github.com/MeshSr/common-bin common-bin]<br />
 
−
This repo stores the common FSBL, SSBL(u-boot), Linux kernel(uImage) and root file system(rootfs), as well as the SDN/OpenFlow executables. It is easy to find them in the repo according to the folder and file names.<br />
 
−
The boot loaders are board-dedicated, while the kernel image and the rootfs are applicable to all ONetSwitch boards.<br />
 
−
* ready-to-download<br />
 
−
This is a sub-folder associated with each project, usually contains the FPGA image(system.bit) and the project-specific devicetree blob(devicetree.dtb).<br />
 
−
The boot.bin, which is created by Xilinx SDK, always consists of the common FSBL and u-boot from common-bin above, and the project-specific system.bit.
 
−
 
−
An example here to prepare for an OpenFlow software switch (ofs-sw) on ONetSwitch30 using pre-built images.<br />
 
−
You need to collect following items and make copies of them to the FAT partition.
 
−
 
−
| File | Repo | Link | | ---- | ---- | ---- | | boot.bin | onetswitch30 | [https://github.com/MeshSr/onetswitch30/blob/master/ons30-app51-ref_ofssw/ready-to-download/boot.bin ready-to-download/boot.bin] |<br />
 
−
| devicetree | onetswitch30 | [https://github.com/MeshSr/onetswitch30/blob/master/ons30-app51-ref_ofssw/ready-to-download/devicetree.dtb ready-to-download/devicetree.dtb] |<br />
 
−
| kernel | common-bin | [https://github.com/MeshSr/common-bin/blob/master/kernel/uImage kernel/uImage] |
 
−
 
−
You need also to extract the compressed rootfs to the EXT partition and then put the application images to somewhere in the extracted folder structure.<br />
 
−
In this example, some runtime libs are required so the sw-lib is copied as well.
 
−
 
−
| File | Repo | Link | | ---- | ---- | ---- | | rootfs (EXT) | common-bin | [https://github.com/MeshSr/common-bin/blob/master/rootfs/rootfs_ext4.tar.gz rootfs/rootfs_ext4.tar.gz] | | sw-lib | common-bin | [https://github.com/MeshSr/common-bin/tree/master/lib lib/*]| | sw-app | common-bin | [https://github.com/MeshSr/common-bin/tree/master/ofs-sw ofs-sw/*] |
 
−
 
−
Notice that, all the boot.bin are prepared to start the kernel in the EXT partition, using the pre-built u-boot with suffix -ext.elf in its file name. If you want to simply run all in an FAT partition, rootfs as uramdisk and the u-boot with suffix -ram.elf. The FPGA image should be used in the boot.bin regeneration.

==== Build the System ====
 
−
 
−
===== Zynq Hardware Design =====
 
−
 
−
The Zynq hardware design generates the system.bit, defining the ARM CPU settings in Zynq PS and the FPGA bitstream in Zynq PL.<br />
 
−
* Create IP cores and hardware design * Configure the processor * Add and integrate IP cores * Generate the bitstream * Export the hardware design to SDK
 
−
 
−
The entire process is implemented in Xilinx Vivado tool. See more information in our [https://github.com/MeshSr/wiki/wiki/Guide-Hardware-Design Hardware Design Guide].
 
−
 
−
===== Zynq Software Design =====
 
−
 
−
The Zynq software design introduces several steps to build up an entire embedded system, from boot loader to Linux kernel, including * First stage boot loader, FSBL * Second stage boot loader, SSBL, using u-boot * Root file system, rootfs * Device tree * Linux kernel
 
−
 
−
The process needs Xilinx SDK, and working environment in Linux with cross compiler installed. See more information in our [https://github.com/MeshSr/wiki/wiki/Guide-Software-Design Software Design Guide].
 
−
 
−
===== Application Design =====
 
−
 
−
The applications, often the final target what we want, run on top of the OS (Linux as we mentioned above, or any others from 'bare-metal' to Android.)<br />
 
−
For SDN/OpenFlow application, we have done following and hope to get more from you.<br />
 
−
* A vSwitch running a CPqD ofsoftswitch13 ported to ARM [https://github.com/MeshSr/ofs-sw <tt>ofs-sw</tt>]<br />
 
−
* An FPGA accelerated OFS, with both HW and SW flow tables [https://github.com/MeshSr/ofs-hw <tt>ofs-hw</tt>]
 
−
 
−
==== Integrate and Test ====
 
−
 
−
===== Prepare the Boot Image =====
 
−
 
−
The boot image, boot.bin, is created in Xilinx SDK, by assembling the FSBL, the FPGA image, and the SSBL in sequence.<br />
 
−
1. Select 'Xilinx Tools' from the SDK menu<br />
 
−
2. Choose 'Create Zynq Boot Image', a pop-up appears<br />
 
−
3. Add ''fsbl.elf'', ''system.bit'', ''u-boot.elf'' sequentially<br />
 
−
4. Click 'Create Image' and wait for the generation<br />
 
−
5. Rename the output binary to ''boot.bin''
 
−
 
−
===== Use the Test Sequence =====
 
−
 
−
Project-specific test sequence is provided as a demo. It mainly shows the usage of the board and the features of the application.<br />
 
−
Try the test sequence and check the results.

−
# bootable SD card
 
−
 
−
==== Task Description ====
 
−
 
−
The following instructions are taken from the OMAPPedia wiki.
 
−
 
−
The following instructions assume a Linux system. Furthermore, most commands require root permissions. After completing this steps the SD card holds two partitions which can be read/written under Linux. Windows can - if at all - only access the FAT partition; but even this seems to depend on the card reader/driver used.
 
−
 
−
Insert SD card and figure out the corresponding device. The last lines of the dmesg output should tell you under which device file the inserted SD card is available in the system. dmesg
 
−
 
−
Warning: The following commands will use '/dev/sdX' to refer to the SD card device. Replace this with the actual device on your system. Executing the following commands on the wrong device may corrupt your data on other file systems. Also, all data on your SD card will be destroyed.
 
−
 
−
The fdisk utility does not seem to erase the first few bytes of the first sector in the card when the partition table is saved. Use dd to erase the first sector. <tt>dd if=/dev/zero of=/dev/sdX bs=1024 count=1</tt>
 
−
 
−
Calculate the new_cylinders value <tt>fdisk -l /dev/sdX</tt>
 
−
 
−
The output should look similar to this > Disk /dev/sdb: 8068 MB, 8068792320 bytes<br />
 
−
249 heads, 62 sectors/track, 1020 cylinders, total 15759360 sectors<br />
 
−
Units = sectors of 1 * 512 = 512 bytes<br />
 
−
Sector size (logical/physical): 512 bytes / 512 bytes<br />
 
−
I/O size (minimum/optimal): 512 bytes / 512 bytes<br />
 
−
Disk identifier: 0x00000000
 
−
 
−
Disk /dev/sdb doesn't contain a valid partition table
 
−
 
−
Look for the size of the device in bytes and calculate the new number of cylinders using the following formula, dropping all fractions: > new_cylinders = <size> / 8225280
 
−
 
−
For the example output given above, we would write down '''new_cylinders = 8068792320 / 8225280 = 980'''.
 
−
 
−
Partition the SD card. We will create two partitions on the SD card. One 200 MB sized boot partition. And a second partition taking the remaining space on the SD card.
 
−
 
−
<tt>fdisk /dev/sdX</tt>
 
−
 
−
The dd command should have wiped all existing partition tables, if this is not the case, delete all existing partitions on the SD card. >Command (m for help):<br />
 
−
Partition number (1-4): 1<br />
 
−
Repeat this for all valid partitions numbers.
 
−
 
−
<blockquote>Now configure the sectors, heads and cylinders of the SD card.<br />
 
−
Command (m for help): x<br />
 
−
