Re: Re: About the FreeScale e500 series processor



hi,
thx for your answers!!!
It looks like there no a special mailling list for this port(PowerPCSPEPort) and it looks like a non-offical supported architecture. Is  there any downloads available?
If this port is stable enough(Less kernel panic, support most software such iscdhcpd, bind and so on), I think I can use this as the OS of my product and I can also contribute some code if I can. :)

The e300 core based cpus like 5200, 512x,.. can run debian-powerpc as
it. There is an overview at [0]

    Hi Bear.

    I have been running Debian for years on the following embedded PowerPCs:

    MPC60x (rather old)
    MPC7457
    MPC8540

    The MPC8540 has an e500 Version1 core, which is compatible with 
older PowerPCs, at the condition that FP instructions are emulated in 
the kernel, because it does not implement FP instructions.

    But e500v1 is now obsolete and e500v2 features a full set of 
instructions which are incompatible with older cores: FP instructions 
but not only, and some other instructions have been removed and are not 
emulated in the kernel (at least up to 2.6.34). Hence the need for a 
port to powerpc-linux-gnuspe. BTW, why not powerpcspe-linux-gnu?

    I am now running this Debian/Lenny port on MPC8548E (e500v2). Big 
thanks to the people who are working on the port:

Is there anyone who can tell me the answer? Or, if the powerpc edition of debian is only for Apple's powerpc processor? And also, is there any FreeScale's processor can run debian-powerpc? thx!

The e500 core is not compatible with the debian-powerpc
architecture. However, a new debian architecture (powerpcspe) is
currently being created specifically for the e500 cores. The debian
ports page for it is here [0].

From the build stats page [1] you can see that over 90% of the debian
packages have already been built. Be aware that there are several open
bug reports, including a compiler bug that has currently stalled the
project.

You may also want to ask Freescale about this port. I expect that
Freescale is also interested in seeing this port become official.

Have a look at the SPE port:
http://wiki.debian.org/PowerPCSPEPort

If you drill down far enough in Freescale's info about the chip series
you're asking about, check their "Software & Tools" links for refs to
several embedded OS vendors like QNX, Windriver, etc. that have
supported these platforms for many years on stable, production ready
embedded platforms.
