It is right then, it is not defined in your FreeRTOSConfig.h. Any macro that is prefixed ‘config’ is a user editable macro that can be placed in the FreeRTOSConfig.h. If a macro is missing from FreeRTOSConfig.h then in many cases it will be defaulted, but not in the case of configMAXSYSCALLINTERRUPT_PRIORITY because it is very much dependent on the chip you are using. Did you try Googling configMAXSYSCALLINTERRUPTPRIORITY? That is normally the first thing to be done. When I try this the first link I get is this: http://www.freertos.org/a00110.html then searching this page for configMAXSYSCALLINTERRUPTPRIORITY I find this information: http://www.freertos.org/a00110.html#kernel_priority
