Translated from FreeRTOS official website document, original website: http://www.freertos.org/RTOS-Cortex-M3-M4.htmlReprint: Original source: Http://bbs.ednchina.com/BLOG_ARTICLE_3009240.HTMThousands of FreeRTOS applications run on the arm cortex-m core. Surprisingly, the RTOs is used in combination with the Cortex-m kernel, making the request for technical support so much less. Most of the problem points are caused by incorrect priority settings.

Background: RAID is a Redundant Array composed of multiple low-cost disks. It appears as an independent large storage device in the operating system. RAID can give full play to the advantages of multiple hard disks, increase the speed of the hard disk, increase the capacity, and provide Fault Tolerance functions to ensure data security. In the case of any disk failure, you can continue to work, the disk will not be damaged. RAID can be divided into soft raid and hard raid. Generally, medium and

Cortex-M3 learning and debugging of stm32f10x UART In the process of learning the stm32f10x Development Board, the first learning routine is the UART Printing program. Due to the previous experience of single-chip microcomputer, UART programming is not unfamiliar, however, in order to lay a solid foundation for programming, the routine should be analyzed and introduced in detail, hoping to discuss with those who share common interests.1. stm32f10x UAR

Ti official website download stellarisware package, decompress by default path, in c: \ stellarisware has multiple folders, where C: \ stellarisware \ board \ rdk-s2e folder is the main character: source code for serial port to Ethernet. It uses lwip1.3.2 as the TCP/IP protocol stack. TI's serial port to Ethernet module can quickly convert serial transmission to Ethernet transmission. The module includes a microcontroller based on ARM cortex m3, a pai

byte in length, many other commands are 2 or 3 bytes in length. This is usually the case for a 16-bit architecture, where some commands may occupy 6 bytes or more memory.ARM Cortex-M3 and Cortex-M0 processor leverages ARM Thumb-2 technology that provides excellent code density. With Thumb-2 technology, the Cortex-M processor can support the fundamental foundation of 16-bit Thumb commands that have been extended to include more powerful 32-bit command

I am using NXP cortex-m3 chip LPC1768 as the master chip, after repeated research and experiments, modify startup. the size of stack_size and heap_size in s Code does not help. However, there is a strange phenomenon, that is, the single-step debugging can only be executed once, and the results obtained this time are correct, then there will be a hardware error immediately and an endless loop of hardware errors will be entered into the assembly languag

The stm32-M3 has a system time base timer, which is a 24-bit descending counter. After the system time base timer is set and enabled, the counter is reduced by one every time the system goes through a clock cycle. When the counter is reduced to 0, the base timer automatically loads the initial value, continue to count down, and the internal COUNTFLAG flag will be set to trigger the interruption. The system time base timer function is simple, and only

This version of MySQL continues to improve the InnoDB Storage engine, mainly including: The InnoDB Storage engine is upgraded to version 1.1.1, which is also the latest development version. InnoDB uses a hash table to store redo logs during restoration. In 64-bit systems, the hash table size is 1/8 of the buffer pool size. To reduce memory usage, the size of the buffer pool for the hash table is adjusted to 1/64. If it is a 32-bit system, it is 1/128. In the slow query log, the Rows_examine

At present, the most common embedded operating system on the CORTEX-M3 platform is ucosii, in addition to support the mainstream embedded operating system is difficult to see, this is because CORTEX-M3 frequency is low (common 72M), does not support MMU, In-chip flash and in-chip ram are relatively small and so on, these limitations, such as wince system, embedded Linux, such as the need for MMU support sys

First, background:Recently, a project has been taken over, the core chip is both the LPC17XX series MCU, core arm of the COTEX-M3 core.If you want to play with an MCU, you have to take care of its clock!The clock is to the MCU, like the human heart. It gives the AHB, APB Bus The blood (clock frequency), and the devices that hang on the AHB (Advance High bus) bus are like our various organs, the peripherals that hang on the APB (Adance peripheral bus)

Comparison of CORTEX-M3 and ARM7In March 2005, ARM announced the latest ARMV7 architecture and defined three major series:the "A" series is designed for cutting-edge virtual memory-based operating systems and user applications. Mainly for the growing running of consumer electronics and wireless products including Linux, Windows CE and Symbian;The "R" series is for real-time systems. Mainly for systems that need to run real-time operating systems for c

Today the company's IBM x3650 M3 to strike, fortunately, the data in the basic is not needed, you can kill the reload. It used to be a lot of servers to contact Dell, so the IBM server was really smattering, and now it's just a chance to know I'm not going to let go, so I started starting with the initial reconfiguration of the disk array raid.First, RAID configurationon this part, I think a lot of people have written such articles, so I do not write

When the CentOS IBM system X3650 M3 server is installed on the IBM X3650 M3 and CentOS 5.5 is directly installed on the CD, the disk cannot be found at the partitioning step, you must manage the hard disk and set it to raid0 before installing the linux system. If the server displays "+" during self-check, you must set the disk to install the operating system. If "+" appears, you can directly install the ope

In the next line of the first function systeminit (), there will be another common function.Nvic_prioritygroupconfig (nvic_prioritygroup_x)(X indicates numbers 1, 2, 3 ...). This function is related to the interrupt configuration. It configures the interrupt priority, including the preemption priority and subpriority. Introduction to Objective C (interrupt vector Controller) cannot be found in the stm32 reference manual. Need to seeAuthoritative guide to Cortex-M3This book focuses on the
