I require free and light RTOS for RL78 device.
If anyone know please share.
have you tried some of RTOs here link->www.freertos.org/RTOS_RL78_IAR_Demos.html
In reply to JB:
Micrium also has RL78 support. www.micrium.com
And of course there's always Proto-Threads if you want to get a REALLY lightweight setup. dunkels.com/.../index.html
It can be enhanced with a very simple priority scheduler, based on an interrupt tick timer or without: http://www.embedded.com/design/prototyping-and-development/4007566/1/Building-instant-up-real-time-operating-systems#
