N9 kernel Update Project
 

Hello sailors,
I complete the process in GitHub.
https://github.com/nemomobile/kernel-adaptation-n950-n9
I'm compiling to kernel with sb2 arm compliler.

I get stuck at some point.

https://wiki.merproject.org/wiki/N9_...update_project

"Build instructions from git" I proceed from the point.

Re: N9 kernel Update Project
 

I have not used scratchbox2 for compiling to N9 but it looks to me you have some misconfiguration in scratchbox itself.

Re: N9 kernel Update Project
 

It took 5 hours.

Re: N9 kernel Update Project
 

Is there a shortcut?

Re: N9 kernel Update Project
 

So you did manage to compile it after all?
What was the fix, reconfiguring scratchbox? Missing dependency?


Do you mean is there an alternate way to compile the N9 kernel?
Yes, there are lots of ways you can do it. Using scratchbox is one, using just the crosscompiler without chrooting is another, and using native compiler on the device itself is third.

However compiling on any crosscompile-method on any decent PC hardware should not take 5 hours! Less than 30 minutes is something you'd expect.
(except if you are compiling on cygwin env under windoze or something silly like that... then it might as well take a week or so :eek:)

Re: N9 kernel Update Project
 

Only one problem has.
sudo ./copy_kernel.sh /<path-to>/<mounted>/<N9 filesystem>

Re: N9 kernel Update Project
 

I solved other problems.
It's about the n9_mer_defconfig file.
