These images are provided in two variants + - one for downloading the software packages over the network + (available at &armmp-netboot-sd-img;) and one for offline + installations using a Debian CD/DVD (available at + &armmp-hd-media-sd-img;). To save space and network bandwidth, the + images consist of two parts - a system-dependent part named + firmware.<system-type>.img.gz, and a + system-independent part named partition.img.gz. + + + To create a complete image from the two parts on Linux systems, you + can use zcat as follows: + + zcat firmware.<system-type>.img.gz partition.img.gz > complete_image.img + + On Windows systems, you have to first decompress the two parts + separately, which can be done e.g. by using 7-Zip, and then + concatenate the decompressed parts together by running the command + + copy /b firmware.<system-type>.img + partition.img complete_image.img + + in a Windows CMD.exe window. + + + Write the resulting image onto an SD card, e.g. by running the + following command on a Linux system: + + cat complete_image.img > /dev/SD_CARD_DEVICE + + After plugging the SD card into the target system and powering the + system up, the installer is loaded from the SD card.
