Modern Linux on A1200/A3000
I have used https://buildroot.org/ to create a modern embedded Linux system for Amiga A500/A600/1200 (with accelerator) and A3000 (no accelerator needed).
Requirements: A minimum of 8 mb of memory
- Kernel: 4.10.3
- libc: uclibc-1.0.22
- tools: ssh, links (text-browser), telnet, uemacs
Download harddisk image (To run on real AMIGA: copy image to disk with utility like dd):
- Harddrive image A500/A600/A1200 version (with IDE hdd): http://files.subsecret.dk/amiga/AmigaLinuxIde.tar.xz
- Harddrive image A3000 version (with SCSI hdd): http://files.subsecret.dk/amiga/AmigaLinuxScsi.tar.xz
- Buildroot config: http://files.subsecret.dk/amiga/buildroot-m68k-config.tar.xz
Demo system running on WinUAE:

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
- Replace module init tools with newer version: module-init-tools-3.15-m68k.tar.gz
- Extract kernel 4.10.3 modules in /lib/modules/ modules-4.10.3.tar.gz
- Finally launch Linux with new kernel vmlinuz-4.10.3.tar.gz

How to build new Amiga kernel yourself
QEMU m68k chroot environment
- Install debootstrap: apt-get install debootstrap
- run apt-get install qemu-user-static
(if version of qemu is lower than 2.12 it has to be upgraded with this binary: qemu-m68k-static.gz
- Run
debootstrap --no-check-gpg --variant=buildd --foreign --arch=m68k unstable sid-m68k-sbuild http://ftp.ports.debian.org/debian-ports/
- 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
- Now manual configure kernel with
make menuconfig
- Select Device Drivers - Real Time Clock - Change selection from M to star for "Oki MSM6242" and "Ricoh RP5C01" (RTC modules should now be build directly into kernel)
- To disable Tux startup logo: Select Device Drivers - Graphics support. Uncheck Bootup logo
- Now build kernel
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/
