Note: it is recommended that you build an RPM ([[Rebuilding OLPC kernel]]) unless you are already familiar with kernel development! |
|||
== Building an OLPC kernel == |
|||
After obtaining the OLPC source (and if desired, making changes), the following steps can be taken to build a kernel on any Fedora Core 6 machine: |
|||
* make oldconfig |
|||
* make |
|||
* make modules_install # as root |
|||
* tar zcvf kern.tar.gz arch/i386/boot/bzImage System.map /lib/modules/$VERS |
|||
(Warning, this needs root and will trash your /lib/modules, if you happen to already have same version. Use "make INSTALL_MOD_DIR=/somewhere modules_install" if you want to avoid using root). |
|||
Replace $VERS above with the proper kernel version that has been built. |
|||
Assuming everything builds correctly, you will be left with kern.tar.gz. This can be copied over to an XO laptop, and the following steps will install the kernel (again, replacing $VERS with the kernel version): |
|||
* cd / |
|||
* tar zxvf .../kern.tar.gz |
|||
* mv System.map /boot/System.map-$VERS |
|||
* mv arch/i386/boot/bzImage /boot/vmlinuz-$VERS |
|||
* ln -sf /boot/vmlinuz-$VERS /boot/vmlinuz |
|||
If not booting off NAND, the additional steps are also necessary: |
|||
* mkinitrd /boot/initrd-$VERS.img $VERS |
|||
* ln -sf /boot/initrd-$VERS.img /boot/initrd.img |
