【GD32L233C-START Review】3. Porting an operating system [Copy link]

Porting an operating system, this topic seems a bit strange. I hate porting anything. My ideal porting is to port it with just a click like RTX.

But this time the RTX chip is gray. I can't tick it at all.

I turned my attention to OSAL. Last time I worked hard on the timer interrupt for this purpose, but I found it very troublesome to migrate it online. It’s not that I can’t migrate it, but I’m afraid it will be unpleasant to use after I migrate it.

So I turned my attention to FREERTOS, which I felt was not too bad either, so I took several tests.

Suddenly I saw a netizen transplanting RT-THREAD NANO and I thought it was good, so I did it again. I specially recorded it.

1. Download PACK

https://www.rt-thread.org/download/mdk/RealThread.RT-Thread.3.1.5.pack

2. Double-click the downloaded file to install it on MDK.

3. At the green diamond, check the rt-thread core.

Fourth, shield and modify the interrupt it.h file:

//void HardFault_Handler(void)

//void PendSV_Handler(void)

5. Compile it and the error message is a section of EORR raw name, which is also blocked.

//#error "TODO 1: OS Tick Configuration."

At this time, the compilation is successful. In fact, the migration has been successful.

The following program is used to test whether it can be run:

#include "gd32l23x.h"
#include "systick.h"
#include "rtthread.h"

static rt_thread_t led1_thr = RT_NULL;


static void thread_led1_entry(void *parameter);


/*!
    \brief      main function
    \param[in]  none
    \param[out] none
    \retval     none
*/
int main(void)
{
    systick_config();

    /* enable the LED GPIO clock */
    rcu_periph_clock_enable(RCU_GPIOA);
    rcu_periph_clock_enable(RCU_GPIOC);
    /* configure LED GPIO pin */
    gpio_mode_set(GPIOA, GPIO_MODE_OUTPUT, GPIO_PUPD_NONE, GPIO_PIN_7 | GPIO_PIN_8);
    gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_7 | GPIO_PIN_8);
    gpio_mode_set(GPIOC, GPIO_MODE_OUTPUT, GPIO_PUPD_NONE, GPIO_PIN_6 | GPIO_PIN_7);
    gpio_output_options_set(GPIOC, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_6 | GPIO_PIN_7);
    /* reset LED GPIO pin */
    gpio_bit_reset(GPIOA, GPIO_PIN_7 | GPIO_PIN_8);
    gpio_bit_reset(GPIOC, GPIO_PIN_6 | GPIO_PIN_7);
	
	  led1_thr = rt_thread_create( "led1",     /*????*/                    
                                  thread_led1_entry,/*??????*/
                                  RT_NULL,/*????????*/
                                  256,    /*?????*/
                                  4 ,    /*?????*/
                                  20);   /*?????*/
    rt_thread_startup(led1_thr);
    while(1) {
//        /* turn on LED1, turn off LED4 */
//        gpio_bit_set(GPIOA, GPIO_PIN_7);
//        gpio_bit_reset(GPIOC, GPIO_PIN_7);
//        delay_1ms(500);

//        /* turn on LED2, turn off LED1 */
//        gpio_bit_set(GPIOA, GPIO_PIN_8);
//        gpio_bit_reset(GPIOA, GPIO_PIN_7);
//        delay_1ms(500);

//        /* turn on LED3, turn off LED2 */
//        gpio_bit_set(GPIOC, GPIO_PIN_6);
//        gpio_bit_reset(GPIOA, GPIO_PIN_8);
//        delay_1ms(500);

//        /* turn on LED4, turn off LED3 */
//        gpio_bit_set(GPIOC, GPIO_PIN_7);
//        gpio_bit_reset(GPIOC, GPIO_PIN_6);
//        delay_1ms(500);
			
			      rt_thread_mdelay(100);
    }
}


static void thread_led1_entry(void *parameter)
{
  while(1)
	{		
	gpio_bit_toggle(GPIOC,GPIO_PIN_7);
	  rt_thread_mdelay(1000);
	}
}

Just a light flashes, compiles and downloads, and the program runs normally.

Flashing light means the transplantation of RT-THREAD NANO is successful
