PROBLEM TO BE SOLVED: To provide a flash memory rewrite device capable of communicating with an outside tool even when the rewriting of a user program including a communication program fails. SOLUTION: An emulation device 1 is provided with an evaluation chip 2, a flash memory 3 and an emulation RAM 4. The flash memory 3 stores a prescribed user program including a program for communicating with an outside tool 10. Firmware is operated by the EVA chip 2 so that communication with an outside tool can be attained according to a writing request from the outside tool 10. At that time, a user program in the flash memory 3 is rewritten by the EVA chip 2, and whether or not the rewriting of the user program is normally ended is judged. |
