雅特力at32F415单片机，设计板子用继电器控制交流接触器，
报`hard fault on thread: tidle0`错误，两块板子，动作几下就报这个错误

rt-thread删减的只剩IO定时0.5s反转控制接触器了
用cm_backtrace定位错误位置`rt_thread_idle_entry`函数中的
`for (i = 0; i < RT_IDLE_HOOK_LIST_SIZE; i++)`或者定位到
`static void rt_defunct_execute(void)`函数中的`thread = rt_thread_defunct_dequeue();`

用雅特力官方的裸机程序，IO定时0.5s反转控制接触器，长时间测试没出现过死机情况
