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

The original project is based on ADS v1.2 and uses J-Flash ARM V4.14c to write the compilation file to Flash.Try to port the project to IAR 6.3. After downloading and running the Debug NOR Flash mode of the sample project GettingStarted in IAR, the following error message is displayed when J-Flash ARM V4.14c is used to connect to Flash:Connecting...-Connecting via USB to J-Link device 0-J-Link firmware: V1.20 (J-Link ARM V8 compiled Sep 22 2011 16:23:23)-JTA

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.
Or, you can

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). Copy the entire Giveio directory to the C:\WINDOWS, and copy the Giveio.sys file under the directory to c:/windows/system32/drivers.3). In the Control Panel, select Add Hardware > N
Keil Download the program sometimes "The connected Emulor is a J-link clone" problem, which means that the identification of the jlink of piracy, should be a new version of the Jlink appear.
My method solves this problem by replacing the file. Replace the folder directly.
Replace the folder is E:\Program files\keil\arm path under the Segger file, replace the file link under, directly delete the original Segger
to understand the sensitive information in the current vro, extract the firmware from FLASH, and then use the previous knowledge for vulnerability analysis and mining. Next, we will provide some ideas for extracting the data from the hardware.16.1.2 hardware data extraction ideas
There are many ways to extract data by accessing the hardware. Generally, you can consider the following three solutions.Extract FLASH and NVRAM using the JTAG interface on
the current function call tree is used.Code window: Used to view and edit source files.Peripherals dialog box: Check the status of the On-chip peripherals.

The 32-bit ARM embedded processor features high performance and low energy consumption. It has been widely used in consumer electronics, wireless communication, network communication, and other fields. Μ Clinux is an embedded operating system designed for non-MMU processors. It supports arm, Motorola, and other micro-processors. Arm-μ Clinux is widely used as an embedded system at home and abroad. The startup and guidance technology of embedded systems is a difficult point in embedded system dev
Introduction
As mentioned above, "If SOC is compared to a person," the debug subsystem is equivalent to a doctor who can detect the health of the body. This section briefly analyzes the debug subsystem of orpsoc.
The debug system serves as two main tasks. In addition to debugging, it is also responsible for programming Flash.1. subsystem structure
2. Structure Description
The entire debug system can be simply divided into two parts: the upper part and the lower part. The upper and lower parts
assembler programs;
Program Compilation: Compile the program through a dedicated compiler;
Software simulation debugging: Simulate the software running status in the SDK;
Program download: Download to the target board through JTAG, USB, and UART;
Software and Hardware testing and debugging: Joint debugging of programs through JTAG;
Download solidified: The program is correct and downloaded to the prod
Experimental content, steps and experience: the understanding of the experimental process, the understanding of the knowledge points in the experiment instruction book.
(1) Why do I need to manually configure the installation files after double-clicking the Giveio and JTAG drivers?
Because the installation file only frees up the drive files and does not add the hardware device to the system, it needs to be handled manually.
SDT, but they can basically find the corresponding ads. New people should not be enlightened here. ADS is the compiler, and axd is the debugger. Compile it into axf and then debug it in arm's Ram.
2 flashpgm
Flash program. When the axf is debugged in Ram, the power is lost, making it easy to modify the program. The debugged program goes down to flash and runs directly on power-on.
There are still a lot of similar software, such as Fluted and flshp, but flashpgm is the best. If someone asks the
