GD32L233C-START Review——03_2.CoreMark Test, RT-Thread-Nano Porting [Copy link]

*(Continued from the previous article...)* This article is about porting RT-Thread-Nano. # 7. Introduction to RT-ThreadRT-Thread, the full name is Real Time-Thread. As the name implies, it is an embedded real-time multi-threaded operating system. One of its basic properties is that it supports multi-tasking. *(This sentence is excerpted from the official introduction)* Simply put, RT-Thread is in the same category as the famous FreeRTOS and uCOS. And it is **domestic** and **open source**. *(Just these two points are worth knowing. If it is suitable, you can actually use it)* **RT-Thread-Nano** is the smallest kernel version of RT-Thread. # 8. RT-Thread-Nano download1. Official address: https://www.rt-thread.org/document/site/#/rt-thread-version/rt-thread-nano/an0038-nano-introduction 2. Keil support package download: https://www.keil.com/dd2/pack/#!#third-party-download-dialog (This method downloads a file in `.pack` format, similar to the chip support package) 3. Attachment download: (The attachment is located at the end of the post) # 9. RT-Thread-Nano porting steps1. Download RT-Thread-Nano source code; 2. Prepare a project that has implemented `printf()` function redirection; 3. **Port RT-Thread-Nano to the project;** 4. **Modify some configurations;** 5. Create a thread to verify that the porting is successful; # 10. RT-Thread-Nano porting* (The following subheadings correspond to the content of the above title **9. RT-Thread-Nano porting steps**)* The hardware platform for this porting is the GD32L233C-START development board. > It is recommended to use the manual source code porting method. Although the installation method of `.pack` is simple and convenient, you only need to check it in Keil's software manager when using it. However, the project using this method cannot be used when copied to a computer without the RT-Thread Package installed, and it will prompt that the RT-Thread source file cannot be found. ## 10.1 Download RT-Thread-Nano source code According to the RT-Thread-Nano source code downloaded from the above address, the folder content is shown in the figure below;

 ## 10.2 Prepare the project that has implemented the redirection of the `printf()` function directly Use the streamlined project that has been created earlier. ## 10.3 Migrate RT-Thread-Nano to the project 1. Create a "sys_base" folder in the project folder, and **copy** the RT-Thread-Nano source code to the folder as shown in the figure below; 
<ignore_js_op>

 ## 10.5 Create threads to verify that the transplantation is successful 1. Create two threads in `main.c`. The `main.c` code is as follows: ```c //#include "gd32l23x.h" //#include "gd32l233c_start.h" //#include "systick.h" //#include "stdio.h" #include "stdio.h" #include "board.h" #include "rtthread.h" /*! \brief main function \param[in] none \param[out] none \retval none */ //Define thread control block static struct rt_thread led_on_thread; static struct rt_thread led_off_thread; //When defining the thread control stack, RT_ALIGN_SIZE bytes are required to align ALIGN(RT_ALIGN_SIZE) //Define thread stack static rt_uint8_t rt_led_on_thread_stack[1024]; static rt_uint8_t rt_led_off_thread_stack[1024]; /****Function declaration****/ static void led_on_thread_entry(void *parameter); static void led_off_thread_entry(void *parameter); int main(void) { //Create thread rt_thread_init(&led_on_thread,"led_on",led_on_thread_entry,RT_NULL,&rt_led_on_thread_stack[0], sizeof(rt_led_on_thread_stack),3,50); rt_thread_init(&led_off_thread,"led_off",led_off_thread_entry,RT_NULL,&rt_led_off_ thread_stack[0], sizeof(rt_led_off_thread_stack),3,50); //Start the thread and enable scheduling rt_thread_startup(&led_on_thread); rt_thread_startup(&led_off_thread); } static void led_on_thread_entry(void *parameter) { while(1) { gd_eval_led_on(LED1); gd_eval_led_on(LED 2); gd_eval_led_on(LED3); gd_eval_led_on(LED4); rt_thread_delay(500); } } static void led_off_thread_entry(void *parameter) { while(1) { gd_eval_led_off(LED1); gd_eval_led_off(LED2); gd_eval_led_off(LED3); gd_eval_led_off(LED4); rt_thread_delay(600); } } int fputc(int ch, FILE *f) { usart_data_transmit(USART0, (uint8_t) ch ); //Send character while (usart_flag_get(USART0,USART_FLAG_TC) == RESET); //Check if sending is completed return (ch); } ``` 2. Compile and download; 3. The following phenomenon occurs;
