In TRACE asynchronous Mode,pb3 or Traceswo. If the system does not require JTAG, PB3 as a gpio, the following settings are required: Rcc_apb2periphc

slow. Eclipse's GNU ARM Environment is complex and difficult to debug. Here, I still recommend the use of em::blocks. Em::blocks small, not as big as Keil uvision, nor as bloated as eclipse. Em::blocks installation, configuration relative Keil uvision is simpler and easier, and Eclipse's environment configuration is more complex and error-prone. Em::blocks's code-editing environment is quite intelligent and relatively keil uvision much better than eclipse. Em::blocks embedded the GNU compiler,

This section describes how to burn bare-metal programs using Oflash and Openjtag. Oflash also supports parallel-burning writing, similar to Openjtag. If you want to use Jlink burn write, need to install Segger J-flash tools, here we do not introduce more.First, you need to install Oflash,oflash from the development board manufacturer or download from the Internet. Copy the Oflash to the "/usr/bin" directory by adding the executable permission . The command is as follows:　　　　sudo cp oflash/usr/bi

Home computer installed WIN10, out of enough and installation files small, want to install QuartusII9.1, according to m$ style, drive is definitely not on. It's a dual-system ubuntu14.04 64-bit. The installation process is not going well and is recorded as a backup of the brain that is already out of mind.According to the normal steps to install, and play a good patch SP1 and SP2, basically smooth, here is to note that some of the installation script is declared in the shell is Cshell, run-time

image. Personal opinion, it is easier to use image at the beginning of a transplant, although TFTP is a little more time-consuming to download, but reducing the intermediate decompression steps can reduce the chance of error and speed up development progress.After jumping to Linux, it is necessary to debug with JTAG, such as setting a hardware breakpoint at 0x80008000, because it is a compilation code at the beginning. The main task of the assembly c

SOF, POF and elf sof = FPGA internal SRAM configuration data, download through the JTAG, after the implementation of FPGA hardware function, after the electricity is evaporated. POF = Configure the device flash data, download the as mode to configure the device, after power off, the FPGA will automatically read the configuration data from the configuration device, then configure the SRAM inside the FPGA to realize the hardware function of FPGA. If t

For beginners, why not control the output when using PB3 and PB4. The following is an analysis of this issue. First, after the STM32F10X series MCU is reset, the PA13/14/15 PB3/4 is configured as a JTAG feature by default. Sometimes in order to make full use of the resources of the MCU I/O port, theseThe port is set to a normal I/O port. Here's how:In Gpio_configuration (); Configure the GPIO ports used: Gpio_pinremapconfig (gpio_remap_swj_disable,

Bus Blaster v4 Design OverviewBus Blaster V4 is a experimental, high-speed JTAG debugger for ARM processors, FPGAs, CPLDs, Flash, and more. Thanks to a reprogrammable buffer, a simple USB update makes Bus Blaster v4 compatible with many different JTAG debugger T Ypes in the popular open source software. Based on ft2232h with high-speed USB 2.0 Buffered interface works with 3.3volt to 1.5volt ta

. There are two methods for software upgrade: Through the JTAG interface or through USB cable. The JTAG interface is used to upgrade the program to operate the memory directly through the JTAG interface of the CPU. The JTAG method requires the opening board and corresponding software. The USB cable Upgrade Program r

can help us clarify the problem. Take care of some of the multi-function pins. 3. Select the FPGA configuration Scheme The following table shows the configuration scheme in the original article.There are many configuration schemes, includingActive serial ():Single-chip, with a 3rd-speed configuration by using the intel. The chip is expensive.Active parallel (AP ):Single-chip FLASH (INTEL P30, P33) with a configuration speed of 1st. Chip prices are cheap. However, it takes up to 40 FPGA pins (16

In this case, the Response Message of the SDRAM base address will be displayed, and a final solution will be made. Step 20:Add JTAG UART Jtag uart is a method for generating serial numbers in the PC-to-the-machine sequence and the serial/serial input parameter of the niosii standard. For exampl

When we get a blank board, how does our bootloader burn to flash? One way is to use a simulator. arm has a high-level simulator, and advanced products are good. However, we chose the poor method as a simulator. So what is it? A lot of online searches, jlink, openjtag, USB ..., there are many things, which are cheap in China (everyone knows ). According to the standard, these are actually called adapters. They are an interface, and they can be connected. By the way, they are the

1. Brief DescriptionThe debugging and flash burning functions of jlink are powerful, but it is difficult to perform flash operations on S3C2410 and S3C2440: You need to set SDRAM when burning or flash; otherwise, the speed is very slow; burning and writing NAND flash can only be achieved theoretically, but no one has implemented it directly.In this article, an indirect method is used to burn or write non-NAND flash on the S3C2410 and S3C2440 development boards. The principle is: jlink can easily

stream to a specific FPGA chip, also called chip configuration, on the premise that the function simulation and timing simulation are correct. FPGA is designed with two configuration modes: directly configured by a computer through a dedicated download cable, and automatically configured when the peripheral configuration chip is powered on. Because FPGA has the property of power loss information, you can use a cable to directly download bitstream at the initial stage of verification. If necessa

We didn't pay much attention to it before. Altera provided many online debugging methods in Quartus, In section V. In-system design debugging of Quartus II version 7.2 handbook Volume 3: verification, five methods are introduced in Chapter 5: 1. Quick Design Debugging Using Signalprobe Signal Probe The method does not affect the original design functions and layout wiring, but connects the signals to be observed and debugged to the reserved or unused I/O interfaces by adding additional wiring

How does one mix 1.5 V/3.3v?The development of TI DSPs is the same as that of Integrated Circuits. The new DSPs are all 3.3v, but many peripheral circuits are still 5 V. Therefore, in the DSP system, there are often 5 V and 3 v dsp mixed connection problems. In these systems, Note: 1) the DSP outputs to a 5 V circuit (such as D/A), which can be directly connected without any buffer circuit. 2) DSP input 5 V signal (such as A/D), because the input signal voltage is greater than 4 V, exceeds the D

in the debug header. This is the case of my twr-k64f120m board:Trace Swo pin (from: twr-k64f120m schematic)As shown, the SWO trace pin is shared with the JTAG TDO pin. This means that SWO cannot be used in Jtag, but only in SWD.So carefully check your board's schematic to determine whether he supports SWO. For example, frdm-k64f (a previous version of twr-k64f120m), its swo is not led to the debug header:T

instruction set, and then performing the corresponding operation when the corresponding instruction is found. If we need to compare instructions in our instruction set, we will shorten the comparison between the instructions we write to the CPU and the instruction set, so our CPU processing instructions will be faster. However, there are some very infrequently used instructions in another place, if the CPU can not find the corresponding instructions in the truncated instructions to go to the pl
