'configMAX_SYSCALL_INTERRUPT_PRIORITY' undeclared (first use in this function) portmacro.h

Posted by freertos90 on April 14, 2017

Hello; My portmacro.h file include this function ~~~ Description Resource Path Location Type 'configMAXSYSCALLINTERRUPT_PRIORITY' undeclared (first use in this function) portmacro.h /osiloskop/src line 139 C/C++ Problem

~~~ On the other hand my freertosconfig.h does not include this function FreertosConfig.h is include this: ~~~

'configMAX_SYSCALL_INTERRUPT_PRIORITY' undeclared (first use in this function) portmacro.h

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
