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),

following operations are performed: [Root @ localhost root] # chmod + x your software package [Root @ localhost root] # tar your software package [Root @ localhost root] # cd your decompressed folder Then modify your jtag. h file. For details about how to modify the file, refer to the second website I gave above. The first one is also acceptable, but it is not very detailed. The preceding steps are not described in detail, because they were decomp

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

I'm tired of switching the system to download the u-boot.bin to the development board, I use Jlink, so I always want to make him in the UbuntuLinux environment can also use, when I browsed the Jlink official website, I found some clues. segger has a Linux test version of J-Link, but it is not easy to make Jlink run, after a lot of effort, I finally got some results. The following is a summary of my installation process and I will learn from you: 1. Do

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

Original address: http://group.chinaaet.com/99/472641.i/o, ASDOIn the as mode is a dedicated output pin, in PS and JTAG mode can be used when the I/O foot. 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

Use of cycloneii special pipe head In the forum, I saw a friend posting about the connection of the Altera FPGA special pipe foot, which is very helpful for beginners like me. I checked the cycloneii manual and materials of Altera, add the functions and usage of each special pipe foot. Ep2c5t144c8n/ep2c5q208c8n 1/1. I/O, asdo In as mode, it is a dedicated output foot. In PS and JTAG mode, it can be used as an I/O Foot. In as mode, this foot

configured successfully. 3. Measurement of FPGA-related configuration pin impedance. It is found that the local impedance of the conf_done pin is about 600 euro, and the vcc_3.3v impedance is about Euro; normally, the peer and peer vcc_3.3v impedance is about 9.88k and 10.85k. After removing the pull-up resistance (10 K), the Earth and the impedance of 3.3v are 634 and 1.74k, and the normal value is about 5.75m. 4. Check whether the internal configuration circuit of FPGA is damaged. Ah, unf

written to flash, and then powered on, uClinux willStart in flash? Yes, indeed. Now we need to write the kernel image of uClinux to flash. Write the uClinux kernel imageFlash, and then solder the flash to the PCB or plug into the flash outlet of the Development Board? Of course. If you have a writer. However, few people have such writers. What we needIs a cheap flash writing solution. With JTAG, a JTAG is

The arm Development Board is essentially a small computer system. Therefore, you can compare the Learning Development Board with a PC computer. A new computer needs to be installed with a system (pre-installed by the manufacturer or installed by yourself) before it can be used. In the same way, the Development Board must first burn the software before it can be used. PC computers can be installed on a CD system and used on keyboards and monitors. For Development Boards, you can use the

Before the holiday, I was so glad to have borrowed an easyarm development platform from me that I could finally develop something for fun. Who knows there is no JTAG, with serial port. Then I asked him for a JTAG. He said that JTAG can be used without it. I went to the e-market to buy a serial port. When you are preparing to develop a program for fun at home on h

Chapter 2 compiler and language 14th Q:Q: 00254: What is the error message of unimplemented RDI? It indicates that the connection settings are normal. Is the chip burned?A: It is a JTAG problem. You can try ISP first. If ISP is available, it indicates that the LPC2104 is not damaged and the program can run normally. 15th Q:Q: When I debug the program, the following message is displayed in axd: RDI warning 00159: cocould not open specified device port.
