[U-Boot-Users] IMMAP M5282 correct?

[nafiton smith]

Hello

I am having problems trying to use the net features on a new board 
configuration.
Is it possible that the include/asm-m68k/immap_5282.h file is wrong? It 
seems to not coincide with Motorola documentation about its FEC registers.

Thanks

Well. I don?t know if this is the way to do it. Being a newbie, I must 
be missing something because as I see it, it is imposible that it worked 
before.

After I rebuild the immap file, the board started transmision but not 
received nothing. It was necessary to write the packet length on the FEC 
Receive Control Register ( just as it was necesary to do to make dBUG 
work - my first step with this new board :-) After it, the TFTP works 
very fine (curiosly, far finer then dBUG tftp :-)

Can you see what I am doing awrong?

Thank you

PD: This is the immap_5282.file that get the thing to work:

Hi,

I created the mcf52x2 port using the older patches for u-boot 0.4.0.
I'm working with the Motorola MCF5272C3 evaluation board. The parts
for the 5272 are working very well!

For the mcf5282 I only integrated the old code to be able to compile it with 
the new u-boot version. The code was not tested and still needs some work for 
a stable release. I don't have any 5282 hardware so I couldn't do the work.

I know there are a few people around working at the 5282 port but  I don't
know the status of their work.

Regards,

Josef Baumgartner

Josef, 

I've stopped my work after getting stuck with the ethernet not working 
properly, and having to return the M5282EVB board I barrowed from Arrow. I 
will continue with the work once I receive one of the new M5282LITE boards.

On another subject. I thinking about trying Mandrake 10.0 with the 2.6 kernel. 
Will that cause problem with any of the build tools?

Stuart

Sorry, I don't have any experience with Mandrake 10.0 and the kernel 2.6.
