µVISION DEBUGGER: SLOG FAILS SIMULATING 51MX DEVICES


Information in this article applies to:

  • C51 Version 6.20
  • µVision Version 2.20

SYMPTOMS

The SLOG command in the µVision Debugger doesn't seem to work in simulation when using the Philips MX devices.

A specific example is to create a breakpoint which closes the log file (SLOG OFF) and then attempts to redirect Serial Window output to a new file using SLOG > d:\filename. These same commands work with an 8051 program.

CAUSE

This problem is caused by a bug in the simulation driver for the 51MX that came with µVision V2.20.

RESOLUTION

This problem is corrected in µVision V2.21 (C51 V6.21). You may download the latest updates from the Keil Website.
