Abstract:
1. A debug device for embedded systems, wherein, a processor embedded in the embedded system reads a boot program from a flash memory through a data flash interface in order to execute a boot process, the data flash interface being a type of serial interface, and the debug device including: a memory transmission interface, which is coupled to the data flash interface, used to receive data transmitted by the data flash interface; a data storage module, which is coupled to the memory transmission interface and used to store the data received via the memory transmission interface; a data control module, which is coupled to the memory transmission interface and, when a data control signal in the data flash interface is triggered, stores the data transmitted through a data bus of the data flash interface in the data storage module; and a display module, which is coupled to the data control module and used to receive a control signal from the data control module, for outputting and displaying the data stored in the data storage module.
