I’m using STM32F107VC microcontroller I’m using Ride7 ver 7.42.12.0305 compiler RKit-ARM for Ride7 ver 1.46.12.0305 I have updated my project with RTOS from FreeRTOS 7.1.1 to FreeRTOS 8.2.2 I noted the following: In FreeRTOS 7.1.1 the function vPortYieldFromISR() was defined in the file port.c. Its prototype was in portmacro.h I used vPortYieldFromISR() inside a my IRQ routine (interrupt request). In FreeRTOS 8.2.2 vPortYieldFromISR() wasn’t defined and so I replaced vPortYieldFromISR() with vPortYield(). It seems all ok. Is the replacement correct ?

vPortYieldFromISR() is not intended for direct use, which means, as you have found out, as it it not part of the public API it can change. Please use the portENDSWITCHINGISR( x ) / portYIELFFROMISR( x ) macro instead, as demonstrated on various API documentation pages, for example: http://www.freertos.org/xTaskNotifyFromISR.html
