SD card seems to be the intended target for netboot images. E.g. http://ftp.debian.org/debian/dists/stable/main/installer-arm64/current/images/netboot/SD-card-images/ Maybe worth a try, if you can get advise about the appropriate image for your ARM machine. Those are not ISO9660 but rather partitioned images with a FAT32 filesystem: $ /sbin/fdisk -lu firmware.a64-olinuxino.img ... Disklabel type: dos ... Device Boot Start End Sectors Size Id Type firmware.a64-olinuxino.img1 * 2048 199999 197952 96.7M c W95 FAT32 (LBA) Have a nice day :) Thomas
