Abstract: An embedded device detection method, comprising the following steps: executing a task by an embedded device, wherein the task comprises multiple functions; when an abnormal interruption occurs to the task, obtaining a stack pointer and a program counter corresponding to the abnormal interruption by a detection device, wherein the program counter is configured to record a memory address in use when the abnormal interruption occurs to the task; obtaining a stack space corresponding to a first target function being executed according to the program counter when the abnormal interruption occurs to the task; finding out a second target function before the first target function is executed according to the stack pointer and the stack space; and correcting the task according to the second target function.
