I managed to successfully cross-compile Comedi for the Coldfire uClinux
2.6, however it has several unresolved symbols when I try to load it.
comedi: Unknown symbol pgd_offset_k
comedi: Unknown symbol pmd_none
comedi: Unknown symbol remap_page_range
comedi: Unknown symbol pte_present
comedi: Unknown symbol pte_offset_kernel
comedi: Unknown symbol VMALLOC_VMADDR
comedi: Unknown symbol pte_page
It's probably coming to grief in Comedi's Linux compatibility headers
somewhere, but as this stuff has changed a few times, which version of
Comedi and which kernel version are you using exactly?
I'm running comedi-0.7.70, but the issue is seems be be coming from the fact
that I'm using a nommu arch.
You didn't say what kernel version you were using, but it appears to be
2.6.9 or less. Maybe some of the portability issues have been resolved
in 2.6.12-uc (though probably not all of them).
The implementation of these functions is probably trivial, but It's taking me
a bit since I didn't really understand the VM code before (now I have a small
inkling)
The uClinux folks could probably help you there.
I'll get there, I'm just surprised this hasn't been attempted before.
So you're a pioneer! Good luck!
