When debugging the H-JTAG, there will be a solution for "can't halt the target and make it enter debug state;
First: power-off, short ISP, on the lpc2400 Development Board is the jp6 in the lower left corner, and then power-on, programming several times on the number.
Second: Check the datasheet of norflash, find the address pin of norflash, connect to norflash, and repeat it several times.
Cause: Improper debugging of the H-

Source: http://www.union-rnd.com/xilinx-vs-altera-slices-vs-les/ObjectiveOften a friend asks me, "Am I using a FPGA or X-Home FPGA for this program?" Do they have enough capacity? How do they compare their capacity? "Of course, most of the time, when I design for the customer, I will use the highest capacity products directly, because our products are not sensitive to cost. However, this is still a comparison of the two products, simply write some of
After one months of bump, the problem of the driver of the Development Board finally solved, the time of the maniac also vividly, how many times on the brink of collapse.It's funny to think, before this method is to open the Regedit registry, and then search for Altera related drivers, not specific (may not be searched), and then delete all the Altera USB related registry, it is OK.Have tried this method be

The recent Android project encountered a memory-crushing problem, by analyzing the log to find the memory is trampled on the address, but can not find who stepped down. Generally the problem of stepping on memory, you can use the hardware data breakpoints to find the perpetrators. But in this project, stepping on the memory is in the Android boot process occurs, too late on Jtag, the other is the RAM is dynamically allocated, each boot is different (b

In fact, the memory in the vro consists of three parts: the header is CFE, which is actually the BIOS we are talking about. The following is the NVRAM and firmware area (the two did not study before and after ).
Many of my friends want to use the JTAG line to refresh CFE (for example, if you want to modify some default configurations, or activate memory or overclock). The speed of 8-bit transmission of this parallel port is really slow,

DDR2 Circuit DesignHigh-speed large-capacity cache is an essential hardware in high-speed big data applications. At present, the use of a wide range of high-speed large-capacity memory in FPGA system has a classical low-speed single data rate of SDRAM memory, and high-speed dual-rate DDR, DDR2, DDR3 type SDRAM memory, The DDR series of memory all require the FPGA chip has the corresponding hardware circuit structure support.

In the future, it will be more meaningful to conduct a comparison test of Xilinx DSP architecture FPGA based on the testing method in this article.

Currently, many people install Xilinx and Modelsim separately. Therefore, when using simulation libraries of chip manufacturers such as Xilinx or Altera, libraries cannot be found; because Modelsim does not own the simulation libraries of FPGA manufacturers, you must manually compile these libraries. Below I will introduce three methods to increase the library problem of Xilinx or Altera:
