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

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

Find helloworld. c In the drop-down menu src, and double-click it to edit it. 　　 Edit the code, click Save, and compile 　　 Check the compilation report on the console. If no error occurs, the compilation is successful. Next, you can connect to the Zedboard for board-level debugging. 4. board-level debugging 　　After the application is co

is likely to be controlled independently. 9530 it is easier to rewrite the configuration data. 9630 currently, no public software tools are available to switch out or write configuration data. However, there is no way at all. There are at least two ways to import the configuration data of the goods to the goods. One is to remove the licensed flash chip and copy a flash chip that replaces the commodities. The other is to use the JTAG to read the flash

program memory integrated in P89LPC932 are: System Programming (ISP), program running (IAP), and program in parallel. Generally, ISP programming relies on an external tool (except the conventional parallel programmer) to Program program memory directly integrated into the processor. There are many common external tools mentioned here, and different processor vendors may provide different solutions. For example, based on different programming interfaces, there are multiple methods such as

01.FPGA Jtag interface Download not inProblem reason: The JTAG interface and other interfaces are connected together, the manual shows that the power is added well, a few pins on the weak pull up can work. But the unused pin floats, the voltage is greater than 2.375, so the JTAG pin is hijacked.02. Connector Drawing Anti-Docking connector is a pair of opposite, i

Double-click the Analyze Design Using chipscope to open the Chipscope interface as shown below17, if the JTAG connection is normal, the following window will pop up, this window indicates that the development Board was found to use the FPGA model xc6slx4518, click OK, the upper left corner of the p tag turned green,

Use BDI2000 to debug Linux kernel and modules Hansel@163.com2007-12-22 BDI2000 is a JTAG debugger with high cost performance. It supports multiple embedded processors such as ARM, MIPS, and XSCALE by loading different firmware. What I use isThe mips version of bdiGDB, that is, it can be simulated as a gdbserver and used with gdb for source code-level debugging. The Linux kernel version 2.6.18.8 is used. 1. BDI2000 configuration fileIf the target board

. Although TFTP is a little more time-consuming during download, it reduces the middle decompression steps and reduces the chance of errors, accelerate development. After redirecting to Linux, JTAG debugging is required because it is a piece of assembly code at the beginning. For example, you can set a hardware breakpoint at 0x80008000. The main task of assembly code is to add the ing of the serial port I/O address in the memory ing table, so that th

, The method for adding a non-portal is the same as adding an input pin. Double-click the blank space and enter not in the red circle. Click OK. Then, assign pins, compile, and wait ...... After compilation, let's look at how many resources are used, as shown in, or 66%, Let's make a comparison. In the previous section, we used resources, as shown in. After comparison, it is found that the PIO module occupies a considerable amount of resources. After compilation, you can d

debugging. For example, GDB provided by VxWorks tornadoii belongs to this type. . Simple and Practical printing and display tool [printf] Printf or other similar printing and display tools are estimated to be the most flexible and simple debugging tools. Printing various variables during code execution allows you to know the code execution status. However, printf imposes a lot of interference on normal code execution (generally, printf occupies CPU for a long time) and needs to be used with c

synchronous serial s Tandards,such as JTAG, SPI, I²c and UART as well as synchronous and asynchronous parallel FIFO interfaces.In addition, this device features the new synchronous, Half-duplex FT1248 bus,Which allows an engineer to trade off bandwidth for pin count using 1, 2, 4, or 8 data lines at the up to 30mbytes/s.The I/O structure is 3.3V with built-in tolerance for 5V, allowing the designer maximum flexibility when interfacing with FPGAs.On-b

(general-purpose registers and I/O registers) are also zeroed by the reset operation.There are 5 reset sources for the ATMEGA16 microcontroller, which are:1, power-on reset. When the system supply voltage is lower than the power-on reset threshold Vpot, the MCU resets.2, external reset. When the external pin reset is low and the low duration is longer than 1.5us, the MCU resets.3, the power-down detection (BOD) reset. When the BOD is enabled and the supply voltage is lower than the reset thresh
