0 ` 这边分享一下linux环境下制作sd卡分区的步骤： 1、把sd卡插入PC,我们可以在media下看到sd卡，如图 2、卸载sd卡 [root@localhost ~]#umount /media/TOSHIBA 3、使用fdisk查看sd卡的信息 # fdisk -l ----------------------------------------------------- Disk /dev/sdb: 15.5 GB, *** bytes 255 heads, 63 sectors/track, 1881 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/sdb1 2 1881 15101100 c W95 FAT32 (LBA) ------------------------------------------------------------ 4、删除sd卡的所有分区 //对于分区有两种命令 fdisk 和 parted [root@localhost ~]# fdisk /dev/sd //TAB补齐的效果 sda sda1 sda2 sda3 sdb sdb1 ////这里用的是之前写过的sd卡 [512bytes\|bootloader-\|----fat32--rom----] sdb1是fat32那边的实际操作应为 [root@localhost ~]# fdisk /dev/sdb Command (m for help): m Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only) Command (m for help): p Disk /dev/sdb: 15.5 GB, *** bytes 255 heads, 63 sectors/track, 1881 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/sdb1 2 1881 15101100 c W95 FAT32 (LBA) Command (m for help): d Selected partition 1 Command (m for help): p Disk /dev/sdb: 15.5 GB, *** bytes 255 heads, 63 sectors/track, 1881 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 5、新建一个分区，在分区前面留百/千分1给Supperboot （100M） Command (m for help): n Command action e extended p primary partition (1-4) p Partition number (1-4): 1 First cylinder (1-1881, default 1): 2 Last cylinder, +cylinders or +size{K,M,G} (2-1881, default 1881): Using default value 1881 6、修改分区的system id Command (m for help): t Selected partition 1 Hex code (type L to list codes): b Changed system type of partition 1 to b (W95 FAT32) Command (m for help): p Disk /dev/sdb: 15.5 GB, *** bytes 255 heads, 63 sectors/track, 1881 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/sdb1 2 1881 15101100 b W95 FAT32 Command (m for help): w 保存 The partition table has been altered! 7、格式化分区 [root@localhost ~]# mkfs.vfat -F 32 /dev/sdb1 mkfs.vfat 3.0.9 (31 Jan 2010) [格式化只能格式化分区而不能格式化设备，所以时/dev/sdb1 ] sync mkfs.vfat -F 32 /dev/sdb1 -n linjie //改名字 8、把Supperboot.bin烧写到sd卡 [root@localhost images]# writeboot Superboot.bin /dev/sdb start ........... end ........... ` 1
