Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] The gist of the technical scheme of the invention is the comprehensive use of microprocessors, programmable devices and Ethernet switching units.

[0021] The program storage device is downloaded in the system boot program, which refers to a download method that does not need to take off non-volatile storage devices such as flash when downloading the boot program for the smallest system module. This method mainly uses the CPU on the module, etc. Other boundary-scan devices use boundary-scan timing to program flash.

[0022] A private communication protocol refers to a certain communication specification formulated by a certain unit or company according to its own needs. Different parts of the system can exchange data by using the same communication specification.

[0023] The specific composition of the target application ...

Description

technical field [0001] The invention relates to the communication field, in particular to a multifunctional device suitable for program downloading of the minimum system module of an embedded CPU, testing of the minimum system module and debugging of subsystems. Background technique [0002] The minimum embedded CPU system is widely used in information and communication products, and is generally used to control, collect and forward information on various functional systems or subsystems. The application program runs on the CPU minimum system to manage functional subsystems such as circuit boards. In order to speed up the development speed, the embedded CPU minimum system is often modularized. In the industrialized production of information and communication products, it is necessary to download programs for the smallest embedded CPU system modules quickly and in large quantities and to test the welding integrity of the modules. This test can be called a productive test. T...
