Upgrading Amiga Linux kernel
This is a guide on how to upgrade the kernel for Debian 3.1 for Amiga.
Before upgrading the kernel
- Start up the machine
- install ntpdate (apt-get install ntpdate) as real time clock will be broken after kernel upgrade
- Replace module init tools with newer version: module-init-tools-3.15-m68k.tar.gz
- Extract kernel 4.8.14 modules in /lib/modules/ modules-4.8.14.tar.gz
- Finally launch Linux with new kernel vmlinuz-4.8.14.tar.gz
Known Bugs
- Real Time Clock will not work with new kernel. Use NTP to sync time instead.

How to build new Amiga kernel yourself
QEMU m68k chroot environment
- Use Ubuntu linux distribution for this (Fedora seems to have problems with qemu-m68k binfmt)
- Install debootstrap: apt-get install debootstrap
- run apt-get install qemu-user-static
- Build qemu-m68k-static binary build from branch qemu-m68k-680x0-v2.7.0 at https://github.com/vivier/qemu-m68k
- Or download from here: qemu-m68k-static.tar.gz
- Run
debootstrap --no-check-gpg --variant=buildd --foreign --arch=m68k unstable sid-m68k-sbuild http://ftp.ports.debian.org/debian-ports/
- Copy the qemu-m68-static into sid-m68k-sbuild/usr/bin
- Chroot into sid-m68k-sbuild
- Run
debootstrap/debootstrap --second-stage
- Set (from outside chroot) sid-m68k-sbuild/etc/apt/sources.list to
deb http://ftp.ports.debian.org/debian-ports/ sid main
- exit and re-enter chroot
- Run from within chroot
apt-get install debian-ports-archive-keyring
How to build Amiga kernel yourself
- Get newest kernel from kernel.org
- Extract kernel
- Enter m68k chroot environment
- Run
make amiga_defconfig make make install make modules_install
- Run depmod -a with kernel name, ie
depmod -a 4.10.2-amiga
- kernel image can now be found in /boot and modules in /lib/modules/
