This post just to share my experience.
Finally, today i have installed Ros 4 on my 2 routerboard,a rb112 and a rb 133c.
It rock solid!
Very much better than -old- 3.27 previously installed.
Usually, with prevoius Ros versions, i must uninstall some packages to make the -system- fast and stable.
This time, nothing removed, and work fine...
Nice job MT =)
