*	Replace "echo -e" with "printf" to have the same behavior in dash or bash	Andrei Gherzan	2012-09-20	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	oe-core removed the prerequisite to have sh as bash. POSIX doesn't define any options and furthermore allows 'echo -e' to be the default behavior. This means that in dash 'echo -e' will actually print '-e' and interpret backslashes by default. We use instead 'printf' builtin command with or without '\n' to simulate 'echo -e' or 'echo -n'. 'printf' needs format while 'echo' can be used without any arguments. So 'echo >' was replaced by 'printf "" >'. 'echo' without '-n' flag adds a new line by default so to keep the same behavior of two new lines while using 'echo "\n"', 'printf "\n\n"' is used.

*	ddimage: Add script for writing images to boot media	Darren Hart	2012-03-22	1	-0/+87
	Fixes [YOCTO #1806] Standard practice is to use the Linux "dd" command to write images to boot media. 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. The ddimage script 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 Blacklist defaults to "/dev/sda" o Display useful identifying information about the image and device o Prompt the user before commencing the write The output looks something like this: $ 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 (From OE-Core rev: 87e581bb7da9f1530d190cd023fcf892c8b858f5) Signed-off-by: Darren Hart <dvhart@linux.intel.com> CC: Dexuan Cui <dexuan.cui@intel.com> CC: Joshua Lock <josh@linux.intel.com> CC: Kishore K Bodke <kishore.k.bodke@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
