MPC8245 with its internal UART

MPC8245 with its internal UART

[HappyPhot]

I am new to Linux and trying to port Linux to one of 
my board which has a MPC8245 and uses its internal UART
as my serial console.

Who can tell me which flatform is similar to mine ? I've tried
"make sandpoint_defconfig", but seems not the right one.


thanks,

That's the one I would have recommended.  I don't think there
is any Linux platform port that uses the 8245 internal DUART,
at least not in the public source tree.  The DUART is actually
pretty easy, just use the generic 8250 driver and point the address
to the Embedded Utilities Block DUART.

The 2.6 kernel tree has support for the DUART on 8245 Sandpoint  
systems.  (We added it in the last few months).

If you want to use Linux 2.4.25, you can try CPC45_defconfig
from the Denx Kernel ...

Hi,
  I get this one "linuxppc_2_4_devel-2005-10-25-1440.tar.bz2"
and try "make CPC45_defconfig". But it shows "No rule to make 
target ...."
  Did I do something wrong ?

thank you,

Try "make CPC45_config"
It works fine on my PC ...

Hi,
  I've tried this (CPC45_config) on Denx Kernel 2.4.25,
and my serial console works now. Thank you very much.

  Is there any similar platform for kernel 2.6 ? (i.e. MPC8245
with its internal UART )

thank you,
