Hello,
does anyone know if there is already an eCos port for the MPC5567
(e200z6 core) architecture?
If not, probably for the Fujitsu MB91460 controller?
Greetings,
Vlad

I've done a port to the MB91302 controller, which is a predecessor. It
shouldn't be much effort to do a MB91460 port based on that.

How much time did you spend making it?
Were there any major issues while doing the port?
I'm thinking about how long it would take to do a MPC5567 port on my
own, because this MCU is a little more powerful
than the MB91460 ...

I think in sum it was about 3 - 4 months but you can not compare this because
I had to do the whole port including the initial fr30 architecture port,
mb91302 variant and a platform.
You now have in both cases a running archtitecture port (powerpc or fr30) and
a variant that is very close to what you need. So most of the porting effort
is already done. What you have to do hardly depends on the platform you have
and the drivers you need.
What kind of evaluation board do you have ?

Yes, the architecture and variant part ;-)

You have to decide on your own (or ask ecoscentric if they have a commercial
port ready to use for you). I would be glad to see another fr30 architecture,
with powerpc you have an architecture port that is more established and
tested...

Lars

I still cannot decide between the "FlexDevel Starter" evaluation boards
(with the MPC5567) http://www.tzm.de/Flexray/FlexDevel_Starter.html
and the Fujitsu SK-91465X-100PMC (with the MB91460)
http://mcu.emea.fujitsu.com/mcu_tool/detail/SK-91465X-100PMC.htm .
Well, actually the MB91460 seems to have a fr60 architecture.
Unfortunatelly, I cannot assess whether a new fr60 architecture port
would be necessary for the latter.

Thats a good idea, maybe they have!

That is also a reason why I tend to the FlexDevel Starter Board ...

No, as far as I know the fr60 is absolutely software compatible to fr50 and
fr30. The instruction set architecture did not change as well as interrupt
exception handling.
It seems, you are interested in Flexray. It think most of the time porting
ecos you will spend in developing drivers.

The decision is up to you. I think porting to the MB91460 will be a bit easier
because of the simpler architecture, but if you have done the MPC5567 you
will have a bit more fun with it. (I think I would also tend to the MPC...)

Hello
We are about to start project with MPC5554
http://www.phytec.com/products/sbc/PowerPC/phyCORE-MPC5554.html
and we are interested in such port.
There were some entries in this mailing list but nothing is contributed
so far.
http://sourceware.org/ml/ecos-discuss/2006-11/msg00197.html
However it may help us and community if we join forces, I have
contributed an ESCI serial driver as a part of MAC7100 port
http://ecos.sourceware.org/cgi-bin/cvsweb.cgi/ecos/packages/devs/serial/freescale/esci/?cvsroot=ecos
Afaik ESCI is identical on both chips. INTC and some other peripherals
should be similar or same and I think main effort to get it alive would
be the boot loader.
Regards
Ilija
