Embedded OS entry notes-use RTX as a case: 10. Support for RTX debugging of Keil
Debugging is an important part of software development. For embedded development, this part is actually dependent on the support of some hardware resources (hardware debugger. Debugging of traditional embedded systems depends on breakpoint and single step through ). However, the arm cortex-M series chip has strong support for c

Keil RTX is a royalty-free, deterministic real-time operating system for ARM and cortex-m devices. With this system, you can create programs that execute multiple functions at the same time, and create applications with better structure and easier maintenance.Highlights
Royalty-free and deterministic RTOS with source code
Flexible scheduling: loop, preemptive, and collaborative
High-speed real-time operations with low interrupt latency

RTX API Development recently touched the interface of the RTX to open part, RTX actually have a lot of gameplay, in addition to the customer can use their own messages can also be used in PHP API to do some things, the next side to organize a bit of sharing to everyoneIt is worth reminding that these interfaces need to be set to access or that they will be alerte
The following is an example of a xplain STM32 (using the STM32F103ZET6 CPU) Development Board, which is used to migrate RTX to the board. In order to let people who have just come into contact with the system understand the entire porting process, a project will be re-established to add all the source code (including the RTX kernel) to the project, Instead of using the format of the

System ResourcesThe RTX kernel identifies a task process through the task Process Control module. This module is a dynamically allocated memory unit that stores all the control and state variables of the task process. When a task process is created by calling the os_tsk_create or os_tsk_create_user function, the corresponding TCB is created.The amount of memory that the TCB occupies, as defined in rtx_config.c .The
