METHOD FOR DEVELOPING PROGRAM OF MICROCOMPUTER, AND MICROCOMPUTER AND DEBUGGING DEVICE USED FOR THE SAME METHOD

摘要

PROBLEM TO BE SOLVED: To shorten the flow of debugging operation and to improve the development efficiency by writing the program in the microcomputer on a board directly after connecting an in-circuit emulator while mounting the microcomputer on the board, and then performing the debugging operation. SOLUTION: In a state that the microcomputer is mounted on the board 213, the in-circuit emulator 211 is connected to the board through a probe 212 and a connector 209 and under the control of a control unit 215, the program 214 is debugged. After the program 214 is debugged, the program 214 is written directly in the microcomputer on the board 213. Consequently, a flow of mounting operation for the microcomputer in the debugging can be eliminated to shorten the flow of the debugging operation, thereby improving the development efficiency.
