I'd go for uCLinux . It's been ported for ARM, it has strong user base and a decent portfolio of evaluation boars exists. There are couple of other Linux/ARM projects around and you'll see.
I'd here the port for uCLinux for '51s but google did not show???????
plz where is it????????
Do you really think that a C51 is a good choice for running Unix on?

You were told to forget about Linux combined with C51. Still, you insist on diving in the boiling abyss...
