#define CY_BOOT_INT_DEFAULT_HANDLER_EXCEPTION_ENTRY_CALLBACK in cyapicallbacks.h and provide a function named CyBoot_IntDefaultHandler_Exception_EntryCallback();
Look at Creator help under "callback macros"
Thanks for the info. One question that isn't covered in the Creator help. CmOStart.c doesn't include cyapicallbacks.h, and CY_BOOT_INT_DEFAULT_HANDLER_EXCEPTION_ENTRY_CALLBACK shows up as not defined. Am I missing a step?
Make sure you have got boot component 5.40, which is the actual version, else update components and/or Creator to latest version.
Look into "System Reference Guide" (Creator Help) boot component. Search for "macro callbacks"
CY_BOOT_INT_DEFAULT_HANDLER_EXCEPTION_ENTRY_CALLBACK shows up as not defined You have to #define that.
For others facing this problem:
cyapicallbacks.h must be in your .cydsn directory
Our project supports multiple processors, so our source is in a separate directory. If cyapicallbacks.h is in any other directory, even adding it to the build settings compiler "additional include directories" won't work. The generated source will not have "#include cyapicallbacks.h". Moving this header file to the .cydsn and updating in the "header files" list in the source/workspace explorer view, worked.
Note that this worked even with an older (5.2) version of the cy_boot component.
