It would make little senseĪnyway, since the SD card is usually the only bootable media available on this kind of This option is not available for Raspberry Pi boards. The migration, unless you copy an image on it again, of course. Thus the initial device cannot be used anymore after CAUTION: Any data on the target disk will be lost! Onceĭone, the system will just continue its bootup procedure (and the initial device can be This operation does not require a reboot. When first booting a system built with the -system-type installer option, it will lookįor a larger disk and move to that disk. Thus it should be booted on a compatible system. Of course, the resulting image will reflect this initial architecture, and TARGET SYSTEM ARCHITECTURES debootstick expects a chroot environment built for amd64 or i386 systems, or for Raspberry The added benefit of this approach is that a virtualizedĮnvironment is very convenient for the OS customization phase, before calling debootstick. Qemu-debootstrap -no-check-gpg -arch=armhf -variant=minbase jessie rpi-fsĮxporting the OS files from a virtual machine or a docker container is another option to In order to generate a chroot environment for a Raspberry Pi, you can use qemu- debootstrap(1): The USB device may now be booted on any BIOS or UEFI system.Īn example of chroot environment generation for a PC system is given in the previous Kvm -m 2048 -hda /tmp/img.dd-test # the test itself (BIOS mode)ĥ- Copy the boot image to a USB stick or disk.ĭd bs=10M if= /tmp/img.dd of=/dev/your-device Truncate -s 2G /tmp/img.dd-test # simulate a copy on a 2G-large USB stick The most common workflow is the following.ĭebootstrap -variant=minbase jessie /tmp/jessie_treeĭebootstick -config-root-password-ask /tmp/jessie_tree /tmp/img.ddĬp /tmp/img.dd /tmp/img.dd-test # let's work on a copy, our test is destructive Update grub configuration to show boot menu on serial line. Remove the root password of the embedded system (root login will not prompt anyĪsk for the root password when the system will be booted for the first time. Prompt for the root password of the embedded system and set it accordingly. Is to have the bootloader installed and customized before you call debootstick. Specified, the bootarg is added (like plus). For example, -config-kernel-bootargs "+console=ttyS0 -rootdelay" will add console=ttyS0 to the kernel cmdline, and remove any parameter Sign to get a bootarg added and a minus sign to have it removed from the existingīootloader configuration. Specify boot arguments to be added/removed from the kernel cmdline. Specify the hostname the embedded system will have. Install a default one (depending on the embedded distribution). Specify the kernel that should be installed. If live was selected, or if no such option was specified, System where installer was selected, the system will try to migrate to a largerĭevice on first startup. Specify which kind of system is targeted. A summary of options is included below.ĭescribe which chroot environments are supported.
