Hmm, I have never actually build an rpi kernel. As a good lazy person I always copy the images from github :) and on top of that, I also have not cross complied anything. All has been build on an actual ARM.
So the verification questions are: - you do use the raspberry pi's source tree? (https://github.com/raspberrypi/linux) - and you start with their config file (bcmrpi_defconfig or bcm2709_defconfig) Recently I saw that there is a tool to make a kernel.img from an zImage: https://github.com/raspberrypi/tools/tree/master/mkimage and lastly, for my curiousity: what are you trying to achieve? A hint from Gordan I got som time ago is to look at the kernel srpm for pidora. IIRC, they also build their own kernels. the SPEC file should thus be good documentation on how to build such a kernel (bar the cross compiling) Jacco On 05/25/2015 11:58 PM, Bjarne Saltbaek wrote: > Hi Jacco. > > A little off topic, but hey... :) > > Cann you give me a clue why I fail at compiling my own Raspberry kernel? > > I use a CentOS 6.6 64-bit with the cross-ng tools and QEMU on a > Windows 7 with the image from > http://ftp.redsleeve.org/pub/yum/os/raspi-redsleeve-cli-0.3.img.xz > > I have tried various Raspberry Kernel Cross Compiling guides from the > net but none of them works. > > I get compiled the final zImage and Image but they wont boot on QEMU - > blank screen ( the raspi-redsleeve-cli-0.3.img work ofc on the QEMU). > > BR, > Bjarne > > > On 23-05-2015 14:58, Jacco Ligthart wrote: >> On 05/17/2015 11:42 PM, Joshua Kramer wrote: >>> On Sun, May 17, 2015 at 11:57 AM, Jacco Ligthart >>> <[email protected]> wrote: >>> >>>> Stupid question, did you keep /lib/modules/* from Emlid ? >>> I didn't do that first time around, but after you posted that question >>> I rebuilt my image with the /lib/modules* from Emlid.
