崩溃后堆栈信息如下,详细的log见附件。请查一下lpc_task线程里面可能崩溃的位置。

我们这边尝试只编译demo程序,用gdb也只能看到这些堆栈信息,没法得到更详细的崩溃堆栈信息。
目前初步看调用tkl_wired_get_ip获取完ip地址后,就crash了,麻烦检查一下lpc_task线程,尽可能把依赖平台相关的函数调用做到tkl_wired.c里面去。

c库里面,用了一个8k的局部变量,lpc_task线程堆栈设置的只有4k,导致栈越界

解决方案:删除tkl_thread_create中的pthread_attr_setstacksize(&attr, stack_size);
