Hi Markus,

I want to get uClinux running on a custom board based on the Freescale
Coldfire MCF5484 CPU. First of all, is there anybody out there working
on this???
As far as I can see from the latest the uClinux distribution from
January 2007, there is support for the MCF547x in the 2.4.x Kernel tree.
Would it be difficult to move this part to the 2.6.x tree and adapt this
code to the MCF548x processor? I have no idea how complex this task
might be, so any information on this would be appreciated.
Not particularly difficult. But there is a few little
changes to the ColdFire support (which actually make it
easier to support new CPU variants).
The second question is, that as far as I know large amounts of uClinux
have been merged into linux-2.6 main line. What does that mean exactly,
i.e. which parts have been merged and which directories in linux-2.6
belong originally to uClinux?
Specifically the code that was different in linux-2.4.x/mmnommu
is now intergrated into linux-2.6.x/mm. The flat loader, binfmt_flat,
is merged. Architectures that where non-MMU specific, for example
arch/m68knommu, arch/v850, arch/h8300, arch/blackfin. There is also
a number of drivers for peripheral devices used on these.
Some architectures where some family members have an MMU and some
don't are also in 2.6.x (frv, sh for example, and some ARM support).
If uClinux has been merged with linux-2.6
where is the need for a uClinux distribution by itself? I am a bit
confused about this merge of uClinux and linux-2.6.
The uClinux distribution is a complete kernel+libraries+apps+configs
source package. It builds complete ready to run images for targets.
linux-2.6 is obviously just the kernel part.
Regards
Greg
