Concerning the Bogomips, the last traces where obtained whith a try where
the cache was disabled.
When enabled it looks like this

COLDFIRE port done by Greg Ungerer, [EMAIL PROTECTED]
Coldfire was last reset by a hard reset.

Still seems a lot like a memory setup problem.
Is this your own design board?
Does any other software run reliably on it when fitted with the 5407?
I would double check your SDRAM register setup on that.

Greg

I have 2 boards which are identical except for the processor.
One is based on a Coldfire 5307, the second is based on a Coldfire 5407.
I have no problem to boot the 5307 board using a kernel built for
Coldfire 5307, but I can't boot with the 5407 board using a kernel built
for Coldfire 5407.
Here is the error on the console :

I try this, with cache enabled and disabled, it always failed on line
208 of pages_alloc.c
The processor seems top be correctly set, my (own) boot loader works
well.
I am using the uClinux-dist-20070130 distro.
I am using the m68k-uclinux-tools-20061214 tool-chain.
Which kernel version is this, 2.4.x or 2.6.x?
It sort of seems a little like a memory problem.
What memory size have you specified?
Or did you select to auto-size RAM?
The Bogomips number looks completely wrong too.
Something odd there.
Regards
Greg
