As the most popular FPGA development platform in China, I believe that everyone is not stranger against the red hurricane development board, and the red hurricane is a member of the Weisui company. Beijing Weijing Rui Technology is a domestic leading company in the field of software radio and high-performance signal processing. As a professional team of FPGA / DSP design, Beijing has long been dedicated to the development of FPGA development kits. Here, you will introduce you to the high-performance FPGA development platform of Weiwei's independent research and development.
It is well known that Xilinx's Zynq-7000 series devices are currently recognized as the highest integration chip, which has caused a small response after launch. Recently, Weishi launched Zing SK & SOM based on the Zynq-7000 based basic development platform, consisting of the bottom plate SK and the core board SOM, where SOM is the minimum system board of Zynq-7000. Zuolun has launched Zedboard last year. What is the difference between the two development platforms? How does the Zing SK & SOM platform make full use of Zynq rich resources?
A few days ago, the pavilion has been fortunate from Wei Wei to the Zing SK & SOM development platform. The author can't wait to share with you. Let's take a look at the original factory.
As always, simple black red paper cartridge packaging
I don't know what baby is there in the box?
Wei Shi Rui is still very careful, and the accessories that can be used are allocated, so that users don't have worries. Specifically include:
Set of Zing Sk & Som
USB II download cable one
MINI USB line
USB cable
HDMI cable
RJ45 network cable
Power adapter one
DVD CD
Look at Zing Sk & Som's true, or bright big red, arranged so neatly and orderly, simple and generous.
Many interface peripherals basically meet the requirements of users
I have seen Zing Sk & Som, maybe someone will ask the core module SOM Will not only so small? Bingo, answer. The core plate Zingsom is the smallest Zynq core module, only half of the ID card, but integrates the usual components required by the system, and all user interfaces are concentrated on the bottom plate SK. The design of the SODIMM interface used between the core board SOM and the bottom plate SK makes it easy to remove, and it is very convenient, and the connector is buckled and the groove on the lifting of Zingsom. Or the installation will be reversed when installing.
The design of the core board adds is the biggest difference between ZEDBOARD. The interface configuration of SOM can be said to be unique. When the board SK cannot meet, you can design the bottom plate according to the requirements, and the zedboard interface is fixed, the user can only pass FMC Interface expansion, there is a certain limitations, and Weiweizui is still very flexible in the core board.
Take Zingsom from the bottom plate and feel how small it is SOM.
Inappropriate! Such small volume but integrated system all the chips needed
Two chips are also hidden in the back
Which chips are there on the SOM core board?
1, ZYNQ-7020
2, Micron's DDR3 SDRAM memory
3, Spansion S25FL128SA1F00 Quad SPI Flash
4, Marvel's 88E1116R Gigabit Ethernet Transceiver
5, I2C chip
6, USB3320C-EZK USB processing chip
7, the power module, power supply through the bottom plate SK, then converted to the working voltage required for each chip
8, Micron's NAND FLASH flash memory
9, SODIMM interface
Comparison of peers: Zedboard's zedboard is also the design and development platform of Zynq-XC7Z020. Below the two platforms, the author is suitable for you, and the author tends to zing, I don't know which one I like. ?
Appearance zing is slightly larger than the zedboard size

Although Zing Sk & Som does not have zedboard on the interface, it is convenient to extend the zingsom to other interface boards as the design of its core boards that are mentioned earlier.
After you know the zingsk & som, let's take a look at how to start Zingsk & Som.
Before running the Zing Sk & Som development board, you need to confirm the necessary conditions:
USB TYPE-A turn mini-B cable (provided);
Usb turn UART driver, you can download and install the following address:
http://www.silabs.com/products/mcu/pages/8-bit-microcontroller-software.aspx#usb
After installation, you can view in the device manager-port and determine the port number of the COM.
Serial debugging software PUTTY or other similar terminal debugging software;
The TF card containing binary files (provided).
Before you go:
1. Insert the TF flash card containing the binary file into the TF card slot of the zing SK development board (JM1), and the TF card has pre-installed the file required for the system startup.
2. Set the mode to the TF card start mode:
3. Use the Mini USB Typea-B wire connection development board UART (JU1) and computer; USB II download cable is connected to the development board JTAG interface (JC1).
4, open the PUTTY and make the following settings:
5, the development board is connected to the 5V power supply (JP1), turn on the power switch (SP1), the development board is powered on, and can see the Linux boot process by debugging.
6. Some zing SK & SOM's basic experiments in the combo discs, we will show in LED test. Open the Xilinx Sintering tool, initialize the authentication chip information, and then display the following two parts, including the ARM PS and FPGA PL logic. Double-click the XC7Z020, select the sintered .bit file, then right-click the XC7Z020, select the Program sintering file;
7. After the sintering file is successful, the 8 user LEDs can be seen on the zing SOM board, and there is no problem when the core plate zing SOM board and the SODIMM connection between the interface board SK are detected.
A small episode
When I got Zingsk & Som for the first time, I found that several lead solders of the HDMI chip were put together. Is it a welding problem?
Three local soldering together
As an authoritative development board evaluation platform, the author viewed the schematic exploration in the responsible attitude towards the Wei Shi Rui Company. These pins have also received a network GND, and it can be welded together. It turns out that the author is more, you can use it with confidence.
Three places corresponding to the physical map
Write in the last:
Zing SK & SOM development board is a very nice entry platform developed by Weiwei R & D, fully meets the study requirements for beginners to Zynq-7000. The separation design of the core board and the bottom plate makes SK and SOM are not unique, which can be flexible for hardware platform construction. For beginners and software engineers, Zing Sk & Som is a nice Zynq SoC to play platform; for hardware engineers, you can DIY interface board, play different patterns. Zing SK & SOM has a powerful function, this article is only introduced to the development board hardware, and the board's Demo demonstration, please pay attention to the evaluation of the follow-up of the PS and PL interactions.
Zing SK & SOM Development Kit is willing to sell in the Red Hurricane Mall of Wei Wei, interested people can go to buy.
