Hello, I have just used Phillips MCU P89C51RD2BN. I tested the ISP on independent Flash Magic successfully. I also want to use the command line function of flash magic on uVision2 IDE. But when I add arguments "DEVICE(89C51RD2XX, 12.000) COM(1, 19200) HEXFILE(#H,...) to program from Tool menu of uVision2. The FM program just warns "Invalid path ...directive HEXFILE". So please help me understand and resolve this problem Thanks
