stm32F429IGT6 libopencm3 openocd下的minlink

tonychen0924 · 发表于 2023-9-21 15:39:56

目前我在做的是在ubuntu22.04系统下通过libopencm3-example下的例子minlink烧录到stm32F429IGT6开发板里

openocd的连接方式为打开一个终端，并输入：openocd -f interface/jtagkey-tiny.cfg -f target/stm32f1x.cfg

$ make flash V=1
Using ../../../../../libopencm3/ path to library
FLASH miniblink.elf
(echo "halt; program /home/tonychen/gitee/libopencm3-examples/examples/stm32/f4/stm32f429i-discovery/miniblink/miniblink.elf verify reset" | nc -4 localhost 4444 2>/dev/null) || \
openocd -f interface/stlink-v2.cfg \
-f target/stm32f4x.cfg \
-c "program miniblink.elf verify reset exit" \

直接使用结果如上所示，是不是因为这个频率有问题啊？

问题1：使用的arm-none-cabi-gcc的版本太旧了，导致程序编译问题，升级后使用make编译正常
问题2：提供的例子中的时钟和LED灯的引脚和实际阿波罗stm32F429IGT6并不匹配，更改demo的代码后正常烧录且可以看到效果，代码更改后如下：

#include <libopencm3/stm32/rcc.h>
#include <libopencm3/stm32/gpio.h>

static void gpio_setup(void)
{
/* Enable GPIOB clock. */
rcc_periph_clock_enable(RCC_GPIOB);

/* Set GPIO0 (in GPIO port B) to 'output push-pull'. */
gpio_mode_setup(GPIOB, GPIO_MODE_OUTPUT, GPIO_PUPD_NONE, GPIO0);
}

int main(void)
{
int i;

gpio_setup();

/* Blink the LED (PB0) on the board. */
while (1)
{
         /* Toggle the LED on/off using libopencm3 functions. */
         gpio_toggle(GPIOB, GPIO0); /* LED on/off */

         /* Delay to create the blinking effect. */
         for (i = 0; i < 1000000; i++)
         {
                  __asm__("nop");
         }
}

return 0;
}

备注：后续会写一篇完整的关于该环境搭建的分享贴

通过makefile编译后只有miniblink.elf，另外我也通过文档上写的方式也不行(也是报频率的问题，灯也没有发生闪烁)
