一、描述你遇到的问题

点亮LED程序无法点亮我开发板的GPIO4和5引脚呢？用的官网下载的安装包，其他什么都没添加和修改，就这两个引脚无法点亮，是我的板子坏了吗？？

正常情况下坏的可能性不大。

其他IO都可以，就这两个引脚不行吗？

对啊

zxy1416779440•

能点亮其中一盏灯，就不太可能是板子有问题。大概率还是程序配置的问题。

把你的代码和完整日志贴出来。
PIO_MODE复用要选择0，注意不要把对应的外设打开了。

您看一下

另外不要直接在menuconfig中修改，这种一般建议在代码中直接修改更合理一些。

主要是试验了其他引脚都可以，就是GPIO4和5不好使，所以我才怀疑板子有问题呢

好的，现在还是GPIO4然后1秒时延。
现在重编译再烧录。

用万用表测量GPIO4电压

数值无变化！
现在改成GPIO5再试一下

测量GPIO5电压发现仍然无变化！

现在随机更改为GPIO6实验

测量电压有变化

所以说真的不好使啊！

zxy14167794401


在这里加上5秒延时

laowang231

但是现在其他引脚都好使啊，就GPIO4和5不行

zxy1416779440•

unused(arg);

osal_msleep(5000); /* 上电后延时5秒再开始闪烁 */


uapi_pin_set_mode(CONFIG_BLINKY_PIN, PIN_MODE_0);
uapi_gpio_set_dir(CONFIG_BLINKY_PIN, GPIO_DIRECTION_OUTPUT);
uapi_gpio_set_val(CONFIG_BLINKY_PIN, GPIO_LEVEL_LOW);

添加了5秒延时，重编译烧录后还是没有

zxy1416779440•

不是硬件问题，我们这边测是同样的现象，可能是软件底层复用了这两个IO口。
暂时还没找到哪个地方配置了，换成其他口吧。

小熊梦工厂181

请你们帮忙查找一下解决方案，因为其他程序需要GPIO4和5的情况也无法实现

按照这个来，GPIO5的IO模式是4，GPIO4的IO复用是2
