It�s possible LINUX in PIC

Hy people.
It�s possible install LINUX or FREE-BSD to load in MCU PIC ?
If possible, how version and model MCU minimun ?

Thanks.

Why would you try and put a complicated operating system on an 8-bit microprocessor? Simple task scheduler, finite state machine -> no problem. What would you gain with a full blown O.S (memory management, external resource manager, priority task scheduler, etc)?

Many forum readers would gladly (hopefully) help if you had a specific goal in mind of creating XXXX. For example, creating an application which would dynamically allow you to load new features/tasks through a serial port / flash memory / ethernet or ? would be a worth while project.

Cheers,

I agree, i question for do, it�s possible, PIC with LINUX.
I job in project, creat one switch with 8 ports RJ-45 to controler status of interface remotely, i find a RTL8309SB to job, but i do not know conect my PIC with MII PHY mode from RTL8309SB, but i find routine to LINUX.
My project it�s complicade, this product it exists, but high price.

I'd really have to say that 'Linux' is not possible. However in the past, there were mini 'unix alike' OS's implemented on quite basic processors, which could probably be recoded onto a larger PIC. However it'd involve a hell of a lot of code. I'd guess at probably something like about six months of programming, to give a basic command prompt and file system.
Realistically, it'd be much cheaper to use a processor for which such a micro core is already available. Unless the sales are likely to be in the 100000 off or above area, the 'saving' from the use of a PIC, is not going to be worthwhile...

Best Wishes

Debtor, I go to try another solution.
