 		 #164565 - It makes little sense
Responding to: ???'s previous message
Richard Erlacher said:
It makes little sense to build an ARM target that's not compatible with the LINUX OS via an adapter, when such a handy development platform is available.

To me, it makes little sense to be building your own custom development platform at all when you almost certainly have a perfectly serviceable PC to hand anyhow!

You also still seem to be assuming that any "ARM target" must necessarily be sufficiently resource-rich ("yes, disk drives and all") to be able to support Linux.

I don't think that's true at all - I think there are plenty of "small" systems using ARM7-based micros essentially as single-chip microcontrollers where adding Linux capability would absolutely swamp the true target. And it would be completely out of the question for many (most?) Cortex-M3-based targets...
