Hi Robert
Whilst you are looking at this can I pick your brains for the best of your
rt-preempt kernels to upgrade the DE0-NANO-Soc
mksocfpga image with.
I have already upgraded the existing SD image to Stretch and have it
working, but with the old 4.1.22-ltsi-rt23 kernel
I have crossbuild tools installed and can quite happily build one from your
sources if required
I'd use their 4.9.x branch:
https://github.com/altera-opensource/linux-socfpga/branches/all
as that has rt right now:
https://www.kernel.org/pub/linux/kernel/projects/rt/
But as soon as they open up socfpga-4.13 i'd move to that..
Regards,
That turned out to be a PITA
The socfpga patches do not play nicely with the rt patches.
Lots of failures and some code seems to bear little relation to the patch.
Fixed up 4.9 manually only to find it really did not like some of the
patches.
Never had so much trouble with a rt-preempt kernel, they normally patch
and build without problems.
Messed around some more with 4.6 etc but similar problems.
I have stuck with the 4.1.22-ltsi-rt23 kernel, which works perfectly
well. :-P
The main intention was to get it upgraded to Stretch and able to use the new
czmq4 enabled code, which it now does.
I will post the image in http://deb.machinekit.io/uploads/de0-nano/
once cleaned up and minimised as far as possible.
