Create Partitioning using script
- Connect your SD card to a linux machine.
- On your Linux machine open a terminal console.
- Run the following command:
sudo fdisk -l
- Check the mount for your SD card. Look for /dev/sd*** device which matches the memory card size. e.g /dev/sdc/ (Disk /dev/sdc: 997 MB, 997720064 bytes)
user@ubt1004:~/Projects$ sudo fdisk -l Disk /dev/sda: 53.7 GB, 53697576960 bytes 255 heads, 63 sectors/track, 6528 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0007157d Device Boot Start End Blocks Id System /dev/sda1 * 1 19 145408 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 19 6529 52290561 5 Extended /dev/sda5 19 6286 50337792 83 Linux /dev/sda6 6286 6529 1951744 82 Linux swap / Solaris Disk /dev/sdb: 107.4 GB, 107374182400 bytes 255 heads, 63 sectors/track, 13054 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000bc718 Device Boot Start End Blocks Id System /dev/sdb1 1 13054 104856223+ 83 Linux Disk /dev/sdc: 997 MB, 997720064 bytes 31 heads, 62 sectors/track, 1013 cylinders Units = cylinders of 1922 * 512 = 984064 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0005e030 Device Boot Start End Blocks Id System
- Download the script and extract it to your Linux machine.
- Grant execution access to the script using the following command:
chmod u+x mkcard-v0.3.sh
- To create the partitioning run the following command:
sudo ./mkcard-v0.3.sh /dev/sdc
- The result after running the script is as follows:
user@ubt1004:~/Projects$ sudo fdisk -l Disk /dev/sda: 53.7 GB, 53697576960 bytes 255 heads, 63 sectors/track, 6528 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0007157d Device Boot Start End Blocks Id System /dev/sda1 * 1 19 145408 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 19 6529 52290561 5 Extended /dev/sda5 19 6286 50337792 83 Linux /dev/sda6 6286 6529 1951744 82 Linux swap / Solaris Disk /dev/sdb: 107.4 GB, 107374182400 bytes 255 heads, 63 sectors/track, 13054 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000bc718 Device Boot Start End Blocks Id System /dev/sdb1 1 13054 104856223+ 83 Linux Disk /dev/sdc: 997 MB, 997720064 bytes 255 heads, 63 sectors/track, 121 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 * 1 9 72261 c W95 FAT32 (LBA) /dev/sdc2 10 121 899640 83 Linux
- Your SD card is ready with 2 partitions : boot, rootfs.
