This can be error prone and the results of sloppy usage can be disastrous. Locating the device you want to use is a clumsy process, especially on a headless build system. I typically tail dmesg and look for which device was added most recently. I wrote a script (attached) for my own use which does the following: o Check the image and device exist o Check the device is writable o Compare the device to a blacklist and abort if it's listed o Display useful identifying information about the image and device o Prompt the user before commencing the write The output looks something like this: dvhart@rage:/build/poky/fri2 $ sudo ~/bin/ddimage tmp/deploy/images/core-image-sato-fri2-noemgd.hddimg /dev/sdk Image details ============= image: `tmp/deploy/images/core-image-sato-fri2-noemgd.hddimg' -> `core-image-sato-fri2-noemgd-20111202214038.hddimg' size: 318568448 bytes modified: 2011-12-02 13:45:05.298897861 -0800 type: x86 boot sector, code offset 0x58, OEM-ID "SYSLINUX", sectors/cluster 16, root entries 512, Media descriptor 0xf8, sectors/FAT 152, heads 64, hidden sectors 32, sectors 622204 (volumes > 32 MB) , serial number 0x4ed946e0, label: "boot ", FAT (16 bit) Device details ============== device: /dev/sdk vendor: Kingston model: DT 101 G2 Write tmp/deploy/images/core-image-sato-fri2-noemgd.hddimg to /dev/sdk [y/N]? y Writing image... 303+1 records in 303+1 records out 318568448 bytes (319 MB) copied, 53.6766 s, 5.9 MB/s Joshua and Kishore offered some initial feedback, including adding a feature where the script would present a list of available installation devices and allow the user to select from the list if they didn't provide a device as an argument. Joshua pointed me to https://github.com/abock/image-usb-stick which could provide a decent base for a more elaborate form of the tool. Please share your thoughts about whether or not such a tool would be useful and what you would like to see it do. I'd want to ensure that it does at least all of the above and remains usable from the command line (but that doesn't preclude it from having a GUI). 17479 1 285 dvhart 2011-12-02 15:05:37 +0000 Created attachment 285 Darren's prototype script 18240 2 dexuan.cui 2012-01-18 17:41:57 +0000 *** Bug 1737 has been marked as a duplicate of this bug. *** 18978 3 dexuan.cui 2012-03-13 06:28:40 +0000 Since we're creating GUI deploy tool(bug 1738), I think we don't need to supply an extra command line tool. Hi Saul, Song and all, if you agree, can we close the bug, or make a duplicate of bug 1738? 19010 4 dvhart 2012-03-13 16:23:29 +0000 A GUI tool is not a replacement for a cmdline tool. If the GUI tool you are creating cannot be run from the cmdline in an automated way, then we still need a cmdline tool. Several people build on headless build systems and the GUI adds an unnecessary overhead running the graphics over the network (and libraries that must be installed, etc.). It also doesn't work for people who prefer to script various tasks which may include writing the image. 19012 5 dexuan.cui 2012-03-13 16:38:41 +0000 (In reply to comment #4) > A GUI tool is not a replacement for a cmdline tool.

The GUI tool is being integrated as part of the HOB, so it can't run alone from cmdline. > Several people build on headless build systems and the GUI adds an unnecessary > overhead running the graphics over the network (and libraries that must be > installed, etc.).

And, can I assign this bug to you? :-) I think your patch is good enough to be in poky master. 19019 6 dvhart 2012-03-13 19:17:43 +0000 Patch on yocto mailing list adding ddimage to poky/scripts/contrib 19114 7 dexuan.cui 2012-03-14 23:43:31 +0000 (In reply to comment #6) > Patch on yocto mailing list adding ddimage to poky/scripts/contrib Darren, thanks! 19856 8 jiajun.xu 2012-04-04 13:48:57 +0000 QA tested the tool in 1.2 M4 RC1 testing, it could work well. 20073 9 dvhart 2012-04-09 17:00:40 +0000 In poky master: commit af193ae15a2ad2e170d4a9d4bcbfff3e429784f5 Author: Darren Hart <dvhart@linux.intel.com> Date: Tue Mar 13 12:02:51 2012 -0700 ddimage: Add script for writing images to boot media 285 2011-12-02 15:05:37 +0000 2011-12-02 15:05:37 +0000 Darren's prototype script ddimage text/plain 1595 dvhart IyEvYmluL3NoCgojQkxBQ0tMSVNUX0RFVklDRVM9Ii9kZXYvc2RhIC9kZXYvc2RiIC9kZXYvc2Rj IC9kZXYvc2RkIC9kZXYvc2RlIgpCTEFDS0xJU1RfREVWSUNFUz0iL2Rldi9zZGEiCgojIDFNQiBi bG9ja3NpemUKQkxPQ0tTSVpFPTEwNDg1NzYKCmZ1bmN0aW9uIHVzYWdlKCkgewoJZWNobyAiVXNh Z2U6ICQoYmFzZW5hbWUgJDApIElNQUdFIERFVklDRSIKfQoKZnVuY3Rpb24gaW1hZ2VfZGV0YWls cygpIHsKCUlNRz0kMQoJZWNobyAiSW1hZ2UgZGV0YWlscyIKCWVjaG8gIj09PT09PT09PT09PT0i CgllY2hvICIgICAgaW1hZ2U6ICQoc3RhdCAtLXByaW50ZiAnJU5cbicgJElNRykiCgllY2hvICIg ICAgIHNpemU6ICQoc3RhdCAtTCAtLXByaW50ZiAnJXMgYnl0ZXNcbicgJElNRykiCgllY2hvICIg bW9kaWZpZWQ6ICQoc3RhdCAtTCAtLXByaW50ZiAnJXlcbicgJElNRykiCgllY2hvICIgICAgIHR5 cGU6ICQoZmlsZSAtTCAtYiAkSU1HKSIKCWVjaG8gIiIKfQoKZnVuY3Rpb24gZGV2aWNlX2RldGFp bHMoKSB7CglERVY9JDEKCgllY2hvICJEZXZpY2UgZGV0YWlscyIKCWVjaG8gIj09PT09PT09PT09 PT09IgoJZWNobyAiICBkZXZpY2U6ICRERVZJQ0UiCglpZiBbIC1mICIvc3lzL2NsYXNzL2Jsb2Nr LyQoYmFzZW5hbWUgJERFVklDRSkvZGV2aWNlL3ZlbmRvciIgXTsgdGhlbgoJCWVjaG8gIiAgdmVu ZG9yOiAkKGNhdCAvc3lzL2NsYXNzL2Jsb2NrLyRERVYvZGV2aWNlL3ZlbmRvcikiCgllbHNlCgkJ ZWNobyAiICB2ZW5kb3I6IFVOS09XTiIKCWZpCglpZiBbIC1mICIvc3lzL2NsYXNzL2Jsb2NrLyQo YmFzZW5hbWUgJERFVklDRSkvZGV2aWNlL21vZGVsIiBdOyB0aGVuCgkJZWNobyAiICAgbW9kZWw6 ICQoY2F0IC9zeXMvY2xhc3MvYmxvY2svJERFVi9kZXZpY2UvbW9kZWwpIgoJZWxzZQoJCWVjaG8g IiAgIG1vZGVsOiBVTktOT1dOIgoJZmkKCWVjaG8gIiIKfQoKaWYgWyAkIyAtbmUgMiBdOyB0aGVu Cgl1c2FnZQoJZXhpdCAxCmZpCgpJTUFHRT0kMQpERVZJQ0U9JDIKCmlmIFsgISAtZSAiJElNQUdF IiBdOyB0aGVuCgllY2hvICJFUlJPUjogSW1hZ2UgJElNQUdFIGRvZXMgbm90IGV4aXN0IgoJdXNh Z2UKCWV4aXQgMQpmaQoKCmlmIFsgIiR7QkxBQ0tMSVNUX0RFVklDRVMvJHtERVZJQ0V9L0VSUk9S fSIgIT0gIiRCTEFDS0xJU1RfREVWSUNFUyIgXTsgdGhlbgoJZWNobyAiRVJST1I6IERldmljZSAk REVWSUNFIGlzIGJsYWNrbGlzdGVkIgoJZXhpdCAxCmZpCgppZiBbICEgLXcgIiRERVZJQ0UiIF07 IHRoZW4KCWVjaG8gIkVSUk9SOiBEZXZpY2UgJERFVklDRSBkb2VzIG5vdCBleGlzdCBvciBpcyBu b3Qgd3JpdGFibGUiCgl1c2FnZQoJZXhpdCAxCmZpCgppbWFnZV9kZXRhaWxzICRJTUFHRQpkZXZp Y2VfZGV0YWlscyAkKGJhc2VuYW1lICRERVZJQ0UpCgplY2hvIC1uICJXcml0ZSAkSU1BR0UgdG8g JERFVklDRSBbeS9OXT8gIgpyZWFkIFJFU1BPTlNFCmlmIFsgIiRSRVNQT05TRSIgIT0gInkiIF07 IHRoZW4KCWVjaG8gIldyaXRlIGFib3J0ZWQiCglleGl0IDAKZmkKCmVjaG8gIldyaXRpbmcgaW1h Z2UuLi4iCmRkIGlmPSIkSU1BR0UiIG9mPSIkREVWSUNFIiBicz0iJEJMT0NLU0laRSIKc3luYwo=
