µVISION1: CANNOT LOCATE TOOLS

Information in this article applies to:

• µVision Version 1

QUESTION

When I launch µVision, it can't find its DOS executable programs. Why?

ANSWER

This problem may be caused when the DOS PATH specification is too long. Remember that the DOS path limit is 127 chars. If you have run out of environment variable space, you may need to delete some paths that are not required from the PATH specification.

Your AUTOEXEC.BAT should have the following lines in it.

PATH=$PATH;C:\C51\BIN;
SET C51LIB=C:\C51\LIB
SET C51INC=C:\C51\INC

Alternatively, you may specify the current path with the Environment Pathspecs dialog box from the Options pulldown menu in µVision.

Note: Make sure that your CONFIG.SYS has the following lines in it.

Files=50
Buffers=50
