Whilst we always recommend using the latest version of FreeRTOS possible, we understand that older versions are often required for compatibility or compliance reasons.
The version 1.5.1 zip file containing FreeRTOS sources and Demos can be downloaded from license/licensing-agreement/freertos-licensing-agreement-current.html
Previous versions of ADI FreeRTOS are available via Github. There is a branch containing the latest ADI version for each FreeRTOS version : FreeRTOS/branches There is a tag for each ADI released version : FreeRTOS/tags
