[uClinux-dev] question on mcf54451

[angelo]

Dear all,

was interesting in linux running on this cpu.
Seems some user run uClinux on it.
Strangely, i don't see it selectable from both uClinux mmu list, and
same for mainline kernel.
Why ? What do you suggest ?


Thanks

Best regards
Angelo Dureghello

Freescale has their own ports of uClinux and the kernel. You can get the BSP
with all the sources and whatnot from Freescale.

If you want a mainline kernel, IIRC, the '41x is very similar and should boot,
but it wont have support for all the subsystems of the '45x like PCI or USB.

There is non-mmu support for the 5441x family in mainline kernels.
Or did you mean that you only want to use it with MMU enabled?

I recall when I was mainlining the 547x MMU linux code that the 5441x
didn't look terribly difficult to support as well. But I didn't have a 5441x
board to test with, so I didn't try to add it.

Regards
Greg
