RT-Thread-0.4.0 beta2版STM32F107分支，在rtconfig.h添加#define RT_LWIP_DHCP后按复
在rtconfig.h添加#define RT_LWIP_DHCP，其他内容未做修改，官方原版，按复位键系统即崩溃，错误信息如下\ | /

好像不允许按键复位 中断里面用到malloc了。跟踪一下看stack trace，看哪里调用进去了。 汗，网口初始化了可竟然没添加网口中断程序，stm32f10x_it.c程序如下

是否是官方的疏忽？ 中断程序改到stm32_eth.c里了，和3.x相比变化挺大，中断处理函数不太好找了 回复【楼主位】wenhenshi
在rtconfig.h添加#define rt_lwip_dhcp，其他内容未做修改，官方原版，按复位键系统即崩溃，错误信息如下

是的，0.4.0 beta2版本存在这个问题，需要最新的svn版本或这个月发布的0.4.0 rc1版本才能够修正这个问题。 查到原因stm32_eth.c内中断处理函数void EXTI9_5_IRQHandler(void)--》netif_set_link_up(stm32_eth_device.parent.netif)--》
dhcp_network_changed(netif)--》 dhcp_discover(netif)--》result = dhcp_create_request(netif);--》dhcp->p_out = pbuf_alloc(PBUF_TRANSPORT, sizeof(struct dhcp_msg), PBUF_RAM)--》memp_malloc(）;产生的错误
于是写了个函数void XXX（void）；函数内部包含netif_set_link_up(stm32_eth_device.parent.netif)；并把原位置netif_set_link_up(stm32_eth_device.parent.netif)函数屏蔽掉，声明一全局变量初始化为0；
进入中断函数void EXTI9_5_IRQHandler(void)内部原netif_set_link_up(stm32_eth_device.parent.netif)位置把全局变量设为1；
然后把void XXX（void）放到空闲任务函数void rt_thread_idle_entry(void* parameter)中，判断全局变量为1调用void XXX（void）
调用完成后把全局变量设为0；就不崩溃了；具体有没有问题就不知道了，嘿嘿
