Xtensa port for FreeRTOS -- undefined references in kernel build

I’m trying to build the FreeRTOS kernel from a port for Xtensa and am getting errors for undefined references to ‘vTaskSwitchContext’(portasm.S), ‘pxCurrentTCB’(portasm.S), and ‘vPortYieldFromTick’(port.c). They aren’t included anywhere in the port that I downloaded for this processor, although I know they are necessary for portasm.S functionality. Can anyone tell me where I can find these and possibly why they were not included anywhere in the port I downloaded?

Thanks,
Steve White – Intel

Hi Steve - the Xtensa ports are contributed, rather than official. Where did you get the port from? If it was from the FreeRTOS Interactive site then I can probably email the developer to alert him to your question.

Regards.
