Dreamcast port

Hi, my name is Stanislav Obolevich. I am from Riga, Latvia and am
considering a Dreamcast port of Contiki as a graduating project at
Riga technical school. I have all the needed software and hardware
tools ready. KallistiOS parts and drivers can be rewritten to Contiki.
Could you give me some pointers where i should begin porting?

- create a minimal static linked (not using the modular arch) version using 
one of the other ports as a template
- make it use the ctk console lib
- write a few target specific functions (simple console output, simple input). 
lots of stuff can be dummy functions at this point (like input stuff). if 
your target already has some kind of console output, this will be essentially 
about writing some very simple wrapper functions.
- make it compile for the target
- tweak it until it runs and the desktop shows up
- fill in missing functions, add some input functions so you can navigate the 
desktop
- add whatever else you want (statically linked apps, network drivers, 
graphical ctk)

that said, letting it run on top of KOS sounds like cheating to me =P

I'm not planning on using KOS as a runtime. Just to "steal" some of
it's nice code. ;)

Contike l8est stable version & porting guide

Hi,

I am very interested in porting Contiki to my microcontroller board.  I have two questions:

1) What version is recommended to use to begin the port?  I'd like to use the latest *stable* version.  Any info on that would be great.

2) Is there a porting guide or any other info that can be used as a reference?  Usually, a clearly defined porting layer and an ANSI C compiler is all that's needed.

 

Thanks & Regards,

James

GTK network

Hi Contiki Gurus,

I get the following message in the bash shell while executing contiki. 
It starts fine, but cannot access the internet:
tapdev: tapdev_init: open: Permission denied
Font loaded OK
init

Any suggestions as to the cause of the message?

Thanks,

Matt

run it as root? (or give your user proper permissions)

Re: GTK network


Answering my own question:

Running this as root does not produce this problem.
However, it now complains that

sh: line 1: ifconfig: command not found
ifconfig tap0 inet 192.168.2.1
Font loaded OK
init

I am guessing this is because ifconfig is not on the path.

Thanks anyway,

Matt

That's correct.

Also, if you're running 2.6.18 kernel, you may find that merely  
giving the tun/tap devices group writeability from the group contiki  
runs as is no longer sufficient to allow them to work.  This bit the  
Hercules guys a few weeks ago.

Porting to new architecture

Hi,

I have been reading the latest Contiki source code with an eye towards porting to an 8051-based board.  I am having some trouble determining the architecture-dependent functions from the non architecture-dependent functions.  I am looking at the contiki-2.x-20061104 snapshot.  Can someone please guide me as to what I need to do to get the kernel up and running?  I'd be more than happy to write a porting guide doc once I finish my port.  But I need to figure it out myself first!  I will keep looking but any tips would be appreciated.

Regards,

James
