Hello Guys,
I have been having a stab at compiling the kernel with those openWrt b53
drivers , but not having much luck generating the kernel rpm . I have
been following the fedora instructions from here :
https://fedoraproject.org/wiki/Building_a_custom_kernel
And have run into a few issues . Firstly it is the architecture , when
executing this command :
rpmbuild -bb --target=`uname -m` kernel.spec
The target gets set to armv7l , this then unfortunately fails here :
+ InstallName=vmlinuz
+ Config=kernel-3.17.7-armv7l.config
+ DevelDir=/usr/src/kernels/3.17.7-300.R1.fc21.armv7l
+ '[' arch/arm/boot/zImage = vmlinux ']'
+ CopyKernel=cp
+ KernelVer=3.17.7-300.R1.fc21.armv7l
+ echo BUILDING A KERNEL FOR armv7l...
BUILDING A KERNEL FOR armv7l...
+ perl -p -i -e 's/^SUBLEVEL.*/SUBLEVEL = 7/' Makefile
+ perl -p -i -e 's/^EXTRAVERSION.*/EXTRAVERSION = -300.R1.fc21.armv7l/' Makefile
+ make -s mrproper
+ cp configs/kernel-3.17.7-armv7l.config .config
cp: cannot stat 'configs/kernel-3.17.7-armv7l.config': No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.awVfBd (%build)
because the file can not be found . The files in fact is called :
user@bananapi_r1 ~/rpmbuild/BUILD/kernel-3.17.fc21/linux-3.17.7-300.R1.fc21.armv7l/configs $ ls -l

Once I set the target manually to armv7hl , then the build process goes on further . But one thing that concerns me is that that I do not see
any signs so far that my .config file is being used . The one that is copied is the generic one without the b53 driver being enabled . My
.config file is sitting in SOURCES due to this step in the instructions :
cp .config ~/rpmbuild/SOURCES/config-`uname -m`-generic
And it is here amongst other generic .config's :
-rw-r--r-- 1 msou msou 5912 Dec 17 13:52 config-arm-generic
-rw-r--r-- 1 msou msou 14897 Dec 17 13:52 config-armv7
-rw-r--r-- 1 msou msou 20997 Dec 17 13:52 config-armv7-generic
-rw-rw-r-- 1 msou msou 157215 Jan 6 00:33 config-armv7l-generic
-rw-r--r-- 1 msou msou 2169 Dec 17 13:52 config-armv7-lpae
The one I created is config-armv7l-generic , while the others are called just armv7 with no 'l' . So far we have 3 different ways to
designate the platform : armv7 , armv7l and armv7hl and I am not sure which one to use and where .
Best Regards
