Well it looks like it worked! here is the log of the session with a recap below: # dd if=/dev/nbd0p4 of=/dev/sda4 dd: can't open '/dev/nbd0p4': No such file or directory # dd if=/dev/nbd4 of=/dev/sda4 dd: writing '/dev/sda4': No space left on device 1076545+0 records in 1076544+0 records out # mount /dev/nbd4 /mnt/root # mount rootfs on / type rootfs (rw) /dev/root on / type ext2 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw) none on /dev/shm type tmpfs (rw) tmpfs on /tmp type tmpfs (rw) /dev/nbd4 on /mnt/root type ext3 (rw,data=""># df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 2011 1277 734 64% / none 31456 0 31456 0% /dev/shm tmpfs 31456 0 31456 0% /tmp /dev/nbd4 507748 297586 183948 62% /mnt/root # ls /mnt hda1 host usbdev usbdev2 usbdev4 hda2 root usbdev1 usbdev3 usbdev5 # mount /dev/sda4 /mnt/usbdev4 # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 2011 1277 734 64% / none 31456 0 31456 0% /dev/shm tmpfs 31456 0 31456 0% /tmp /dev/nbd4 507748 297586 183948 62% /mnt/root /dev/sda4 507748 297586 183948 62% /mnt/usbdev4 # cd /mnt/usbdev4 # ls bin home mnt sbin tmp boot initrd opt selinux usr dev lib proc srv var etc lost+found root sys 1) the source partition did not like using the name (/dev/nbd0p4) as shown in the "fdisk -l /dev/nbd0" command: # fdisk -l /dev/nbd0 Disk /dev/nbd0: 549.7 GB, 549755813888 bytes 32 heads, 63 sectors/track, 532610 cylinders Units = cylinders of 2016 * 512 = 1032192 bytes Device Boot Start End Blocks Id System /dev/nbd0p1 5 20 16128 c Win95 FAT32 (LBA) /dev/nbd0p2 21 23 3024 da Unknown /dev/nbd0p3 24 26 3024 da Unknown /dev/nbd0p4 27 560 538272 83 Linux It wanted (/dev/nbd4) as shown in the "ps" listing: # ps PID USER VSZ STAT COMMAND 1 root 896 S /bin/sh /linuxrc ... 102 root 920 S /bin/sh -i 109 root 892 S telnetd 112 root 664 S xuartctl --server 116 root 2656 S sdctl -z 65536 --nbdserver lun0:disc,lun0:part1,lun0: 118 root 572 S nbd-client 127.0.0.1 7500 /dev/nbd0 120 root 572 S nbd-client 127.0.0.1 7501 /dev/nbd1 122 root 572 S nbd-client 127.0.0.1 7502 /dev/nbd2 124 root 572 S nbd-client 127.0.0.1 7503 /dev/nbd3 126 root 572 S nbd-client 127.0.0.1 7504 /dev/nbd4 2) The "dd" command reported an error, but is all seemed to work ok: # dd if=/dev/nbd4 of=/dev/sda4 dd: writing '/dev/sda4': No space left on device 1076545+0 records in 1076544+0 records out 3) This "dd" command took several minutes (10 I think) to make the copy, with no feedback, so go get a cup of coffee. I don't know why the size of the partition 4 is all out of sorts. Here is a recap of what I did to make a 1GB Debian Linux Micro SD card for a TS-7500 from a 2GB Debian Linux Micro SD card: 1) equipment used: TS-7500 mounted on the development kit TS-752, the 2gb Micro SD card in the onboard slot, the 1GB target Microcard in a USB thumbdrive reader for the Microcard plugged into the top slot of the USB type A connector on the TS-7500 2) put everything together and booted the TS-7500 with the busybox default OS from embedded arm. 3) the 2gb partition 4 mounts automatically with busybox so I unmounted it with "umount /mnt/root" 4) I checked the current layout of the 2gb card by doing a "fdisk -l /dev/nbd0" command. This listed all 4 partitions, their ID, size, etc. I saved that info for later. 5)I then did a "fdisk -l" this told me that the memory stick was /dev/sda. 6) Next is the "fdisk /dev/sda" command. This is where I muddled through making the 4 partitions. the "m" commant in fdisk tells you all the options, and by repeating the "n" command for each partition, (Primary, first cylinder, +sizeK,) and the "t" command (partition number, hex code(the id) ) and checking things with the "p" command, I got the partitions to "look" about the same as the 2gb. The only difference is I made partion 1 only 20mb, instead of 1.25gb as I was dealing with a 1gb card and not a 2gb card. The last command on the fdisk is the "w" command that actually writes your layout to the card. 7) at the time the blocks seemed to be right, but as thing progressed, they changed. I don't know why but I guess I was "good enough" sorry for the ambiguity. 8) issued the command at the busybox linux prompt "dd if=/dev/nbd4 of=/dev/sda4" to copy over the 4th partition of the 2gb card to the 4th partition of the 1gb card. This took about 10 minutes to complete, and came back with the message: dd: writing '/dev/sda4': No space left on device 1076545+0 records in 1076544+0 records out but I then mounted the partition and it seemed ok. 9) Powered everything down, took out the usb thumbdrive, replaced the 2gb card with the newly created 1GB card, powered up the unit. The busybox linux came up, I typed "exit" to boot the debian linux. Debian linux came up without a hitch. Heres a log of my whole session complete with my typos: # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 2011 1277 734 64% / none 31456 0 31456 0% /dev/shm tmpfs 31456 0 31456 0% /tmp /dev/nbd4 507748 297586 183948 62% /mnt/root # fdisk -l Disk /dev/sda: 1015 MB, 1015808000 bytes 32 heads, 63 sectors/track, 984 cylinders Units = cylinders of 2016 * 512 = 1032192 bytes Device Boot Start End Blocks Id System /dev/sda1 1 984 991747+ 6 FAT16 # umount /mnt/root # fdisk -l /dev/nbd0 Disk /dev/nbd0: 549.7 GB, 549755813888 bytes 1 heads, 62 sectors/track, 17318416 cylinders Units = cylinders of 62 * 512 = 31744 bytes Device Boot Start End Blocks Id System /dev/nbd0p1 5 42282 1310592 c Win95 FAT32 (LBA) /dev/nbd0p2 42282 42348 2048 da Unknown /dev/nbd0p3 42348 42414 2048 da Unknown /dev/nbd0p4 42414 59326 524288 83 Linux # fdisk /dev/sda d 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 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 Command (m for help): d Selected partition 1 Command (m for help): o Building a new DOS disklabel.
