I am currently working on an academic project where I want to implement a RTOS on a LEGO Mindstorms EV3 which runs an AM1808. I have been looking at FreeRTOS and it seems like a very good option if I can get it to work.
As someone who has limited experience in this field (I know C/C++, have worked on embedded projects before, but not real time systems from the ground up). What am I looking at here concerning amount of work to get this up and running (I know, extremely hard to answer)? I have found little to no sources online from other people trying to do the same, so I am looking at adapting one of the ARM9 ports to the AM1808.
Any recommendations and starting tips would be very much appreciated.
