developed in the 1990s S. With the emergence of large-scale integrated circuits, the manufacturing process of printed circuit boards is becoming small, micro, and thin, traditional ICT testing cannot meet the testing requirements of such products. Due to the many pins of the chip, the small size of the components, the density of the board is very large, there is no way to test the probe. A new test technology is developed. The joint test behavior Organization (joint test action group),

Connecting 2_CCS to the simulator in the 335 project development record In actual use, the connection between the simulator and the CCS may have one or another problem. Maybe your connection is successful and you haven't encountered any problems, but I do have many problems, it may be related to computer configuration, or personality; Some of the following errors and solutions are not necessarily correct, but they are also a solution. I would like to share with you: Problem:1.The

Target Board download Mode All in all, the Quartus II software is just a GUI user terminal used to design code and integrate FPGA logic circuits. The ultimate goal is to download it to the target board through USB bluster, parallel port or other means. There are the following types: (1) Configure FPGA--

In fact, the initial prototype of the DD-WRT was released by Cisco, the originator of the router, and was carried on the WRT54G Wireless Router launched by Cisco's Linksys, supporting the highest 54mbps connection speed at that time. Soon, some enthusiasts discovered that WRT54G firmware is based on Linux. However, a basic condition for using Linux as an operating system is that the source code must be open

Now on the market mainstream firmware has dd-wrt, Openwrt,tomato, why have the choice to use Openwrt to transplant WiFiDog do wireless portal? About OPENWRTWhen Linksys released the source of WRT54G/GS, there are many different versions of Firmware on the Internet to enhance the original function. Most of the Firmware are 99% use Linksys source code, only 1% is added to, each Firmware is designed for a specific market, so there are 2 shortcomings,

Jlink) 3. In the transient connection, the two passing holes of A are about 10 s, disconnect, and unplug the USB connector. 4. Use USB to power Jlink again after connecting two backholes of B, and stop power supply after 10 s. 5. Disconnect B through the hole. Iii. Install firmware 1. Open the desktop SAM-PROGv2.4, the following settings: 2. Use USB to connect the PC and Jlink, and then click "Write Flash" to wait for the data to be written, 3. Unplug the USB connection and try again. : Whe

name option, select Create a new user board. The connection method uses JTAG to connect, the big Watermelon FPGA board card does not have the Ethernet, thus uses the Jtag interface.???? In the Configuration Information window of the board, the FPGA chip information on the board is configured first, as shown in.Set the name of the board LOGIC_BOARD,FPGA the vendor is Altera, the chip is Cyclone IV E, select

cheap Flash write solution. With JTAG, a JTAG is set on the s4510b. through the JTAG, we can control all the pins on the s4510b, so that we can input the corresponding commands and data to the JTAG interface, the Flash device read/write operation time sequence is generated on the data, address, and control bus of the

FPGA supports multiple configuration/loading methods. It can be roughly divided into two types: active and passive. Active loading refers to the configuration process controlled by FPGA, and passive loading refers to FPGA only passively receiving configuration data. The most common passive configuration mode is to download bit files using JTAG. In this mode, the device that initiates the operation is a computer, and the data path is a

operating system.The inconvenience of resident monitoring software lies in its high requirement on hardware devices. Generally, application software development can be carried out after the hardware is stable, and it occupies part of the resources on the target board, in addition, the full-speed running of the program cannot be fully simulated, so it is not suitable for some situations with strict requirements.3. JTAG SimulatorThe

devices are connected in parallel (Fig. 3 ). The RS-232C transmitter (txd) is typically connected to all devices, but also supports separation of aging Board areas for multiplexing for further transmission.Each device returns a signal to an RS-232C acceptor (rxd) on the drive board, which can be reused on the drive board. The drive circuit transmits signals to all devices and then monitors the rxd line of the device. Each device is selected and the system compares the obtained data with the res

Summarize the SPI3 problem, because the SPI3 NSS port has a common pin to the JTAG, so misconfiguration can cause SPI3 to be unusable. The following three points need to be noted:1. Configure the PA15 as a normal IO port, gpio_mode_out_pp2. Turn on the AFIO clock Rcc_apb2periphclockcmd (Rcc_apb2periph_afio, enable);3. Turn off the JTAG function to enable SWDGpio_pinremapconfig (gpio_remap_swj_jtagdisable,en

In the as mode, the foot is the CII that sends a control signal to the serial configuration chip. It is also used to read configuration data from the configuration chip of the foot. In the as mode, the ASDO has an internal pull-up resistor that has been in effect until the configuration is complete
