Common errors and solutions
While using Keil C51 v.9.01 Compiler uVision 4 IDE.rar, you may encounter some errors or problems that prevent you from developing or debugging your embedded application. Here are some common errors and solutions that can help you resolve them:
How to fix compiler errors and warnings?
Compiler errors and warnings are messages that indicate that there are some problems or issues with your source code that prevent the compiler from generating valid object modules. Some common compiler errors and warnings are:
Syntax errorThe compiler cannot understand your source code due to incorrect grammar or spelling.Check your source code for typos, missing semicolons, parentheses, brackets, quotes, etc. and correct them.
Undefined identifierThe compiler cannot find a declaration or definition for a variable, function, macro, or type that you use in your source code.Check your source code for misspelled or missing identifiers and correct them. Make sure you include the header files that contain the declarations or definitions of the identifiers you use.
Type mismatchThe compiler cannot perform an operation or assign a value to a variable because the types of the operands or variables are incompatible.Check your source code for incompatible types and correct them. Use type casting or conversion functions if necessary to change the types of the operands or variables.
Out of memoryThe compiler cannot allocate enough memory to compile your source code due to insufficient system resources or memory model limitations.Check your system resources and free up some memory if possible. Use a different memory model or reduce the size of your source code if necessary to fit into the available memory space.
Warning: function declared implicitlyThe compiler cannot find a prototype for a function that you call in your source code.Add a prototype for the function in your source code or in a header file that you include. Alternatively, disable this warning by using the --no_warn_implicit_func option in the compiler settings.
How to troubleshoot debugger problems?
Debugger problems are issues that prevent you from debugging your executable file using µVision. Some common debugger problems are:
No algorithm found for address rangeThe debugger cannot find a flash programming algorithm for the address range of your executable file.Select a flash programming algorithm that matches your target device and address range in the Options for Target dialog box under the Utilities tab.
No connection to targetThe debugger cannot communicate with your target device due to hardware or software issues.Check your hardware connections and settings. Make sure your target device is powered on and connected properly to your debugger interface. Make sure your debugger software and driver are updated and compatible with your target device.
Cannot access memoryThe debugger cannot read or write the memory of your target device due to protection or permission issues.Check your target device's memory map and configuration. Make sure you have the correct access rights and permissions to the memory regions you want to debug.
Cannot set breakpointThe debugger cannot set a breakpoint at the specified location due to hardware or software limitations.Check the number and type of breakpoints supported by your target device and debugger. Use software breakpoints instead of hardware breakpoints if possible. Avoid setting breakpoints in ROM or flash memory regions.
Target runningThe debugger cannot perform certain operations or commands because the target device is running.Stop the target device by clicking on the "Stop" button or pressing the "Esc" key. Alternatively, use the "Halt" command to stop the target device and enter the debugger mode.
