Hi
The linker is expecting to find a code location called resetHandler which it puts to the start of FLASH (this will be defined either in a linker script file or in a project configuration).
This code is usually supplied in an assembler start up file so if it can't be found there are two possible reasons:
1) the assembler startup is not included in the project files. In this case do a search through all assembler files to locate the one needed.
2) the assembler startup is included but it has a different name for this code. (eg. reset_code rather than "resetHandler"). In this case you may be able to change the project define to expect this name or else change the name accordingly.
