Not sure if this is the same pointer Ravi provided one post above the last, just in a different thread: FreeRTOS Ported to RH850
There isn’t an RH850 in the “officially supported ports” as defined here - Officially supported and contributed FreeRTOS code - some definitions - but if there is a need and interest we could look at including one under one of the third party contributed categories - defined on the same page.
