Hi,
We found a issue using EmbeddedRPC on FreeRTOS. When we try to get a semaphore with kwaitForever, the time given to xSemaphoreTake wasn't portMAX_DELAY but something smaller (about 1h in our case).
We also handle the case of timeout >0 but < 1000*portTICK_PERIOD_MS to round up to 1. Which will trig then scheduler instead of returning fail.
The return value is now assigned.
Regards
