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

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.
After openocd is installed, the following problems occur when the openocd command is executed:

Many of the friends who have done microcontroller know that after the MCU is burned to write the program firmware, then the program firmware is stored inside the MCU. The program can continue to operate even if the MCU is powered off and then re-energized. This is because the firmware of the MCU is written to write the program firmware to the MCU on-chip program memory ROM, and most modern MCU this ROM is flash memory. Flash memory can be power-down to keep data, so can realize the power-down pr

When any of them ask you install path, specify
/Opt/altera
Installation will take a long time, especially for quartus and quartus_sp1, sp2.
The programs will be installed in the following directories:
Quartus =/opt/altera/quartus
IP Route core =/opt/altera/ip
Niosii EDS =/opt/altera/nios2eds
Modelsim =/opt/altera/modelsim
After installation,. tar and extracted dir can be deleted.

Introduction
This section describes how to compileProgramDownload to the Development Board.
You need to download the program twice during the development of the program. For the first time, in the Quartus software, we downloaded the configuration file generated by the logic and software to the PV * (* 1,

How to Solve jlink's unable to halt CPU, failure to perform CPU reset operations through jlink, and single-step debugging starting from 0x0.The answers to these questions have been basically found in recent days. It is a bit late now, leaving an introduction to the questions. These questions will be added one by one over the past few days.---------------------- 2010-11-28 supplement ---------------------------------------------------------------From 1 to 5, I have to use this article separatel
I have summarized the programming of the Altera device as follows. I hope to comment on it more ..........
Configuration file:
After the logic code of the Altera us compilation is completed, the system generates the POF (Program object file) programming object file and the sof (SRAM object file) SRAM object file. POF is used to load EPC, and SOF is used to directly configure the SRAM structure of FPGA. The sof file can be converted to the JIC (JTAG

Plug the line into the same port of the PC and connect it with the JTAG, and the JTAG is connected to the 14-pin Jtat Port of the Development Board to open the 2410-s.2).

In my design, the demodulation end uses the MSP430 single-chip microcomputer, because the power consumption of Ti series single-chip microcomputer is very low, in sleep state, the current can reach UA level, under normal operation, the current can also be kept at several Ma levels.

I recently want to develop on the MSP430, and I/O simulation on the first hand will be difficult. Fortunately, there are already many examples of the implementation of the soft serial port of the MSP430 on the Internet. Most of the Code in this article is referred> Logging ....
