Why can I get the Ubuntu ARM distro to run on my Mini2440?
The Ubuntu ARM Distro is based on the ARMv5 instruction set (and ARMv7, Cortex, etc. for netbooks). The S3C2440 ARM920T uses the ARMv4 instruction set. You would have to compile the Ubuntu distro from scratch and solve all the problems that arise. Note that the Mini6410’s easily run Ubuntu. Som people add the tools and do their compiling on the Mini6410. With a VGA adapter, keyboard and mouse, it is a complete system.
