Re: Is it possible to port uCLinux in LPC2106

Started by Leonardo Santos October 4, 2005
Hello All:
Let me disagree with you Sebastian. Embedded Linux IS a viable alternativa,
depending on what you want to do. Is, Linux requires far more RAM and flash
that you would need by writing the software yourself, and Linux, from a O.S.
design point of view, is not a very good embedded O.S., as it divides the
kernel space from the user space.
What you need to do? Linux is great at providing a reliable TCP/IP stack and
a project can benefit greatly if you can get a functionality you need from a
package that already exits, for exemple, you need SNMP on you device, put
Linux on your board and use NET-SNMP. You can get things running very quickly
this way.
But if all you need is a O.S., than Linux might no be the best solution.
Where I work, we have a whole line of routers using Linux, and they work
great, but we use faster processors, as the MPC 8xx from Frescale. So an ARM9
would be a more common choice to run Linux on, not that Linux can\\\'t run on
other processors, but simply because faster processors justify the use of a
complex O.S, because if you could, you\\\'d have selected a cheaper processor
for the task.

Hope it helped, cheers!
