MMC Boot Partitions¶. First, partition the card using fdisk where /dev/sdb is your SD/MMC block device: sudo fdisk /dev/sdb If connected via a SD slot on a device, linux will know it as /dev/mmcblk0 (or mmcblk1, mmcblk2 depending on which mmc slot is used). + +It is possible to define 128 linearly placed partition entries. 1632313515. scr This will produce a boot.
