Hello, I was wondering if there’s a version of FreeRTOS for Renesas RL78 for GCC (KPIT)

Some years ago there was a lot of effort put into providing a port, but on each occasion we ran into compiler issues. It might be that these have since been fixed and that what we have may now work. If you contact Richard using the business contact link on http://www.freertos.org/contact I can send it to you.
