A51: APPLICATION ERROR WHEN CONVERTING LEGACY CODE

Information in this article applies to:

• A51 All Versions

QUESTION

I am converting legacy assembly code from an Archimedes assembler to the Keil A51 assembler. When I compile the code in a DOS window, I get an A51.EXE Application Error at location 0x0CDE. What is wrong?

ANSWER

You should read and apply the Keil Knowledgebase article on converting Legacy assembler code to the Keil A51 assembler. Also check all the Assembler Directives to make sure that they are correct for the Keil A51 assembler. An incorrect directive like $NOCOND or $XR may cause this error to appear when running in a DOS window.

MORE INFORMATION

• Refer to NOCOND in the Ax51 User's Guide.
• Refer to XREF in the Ax51 User's Guide.
