C64x+DSPLIB-2.1-Linux-Install.bin is packaged incorrectly as sprc834.gz when it should be sprc834.tgz or sprc834.tar.gz. Or C64x+DSPLIB-2.1-Linux-Install.tar.gz would have been best. I don't know how you can actually include this library in a project.
I have a rootfs directory which contains all the directory structure to be installed on an gumstix overo board, so (bin boot dev etc home .. var).
What I would like to accomplish, is to make a ubi image of the entire rootfs content, and then install this ubi image with u-boot on my embedded board.
I am not aubi expert so I wrote the following ubi.ini file:
[ubi_rfs]
mode=ubi
image=rootfs.img
vol_id=0
vol_size=7763992576
vol_type=dynamic
vol_name=rootfs
vol_alignment=1
vol_flags=autoresize
I use these two commands to create the rootfs.ubi image:
sudo mkfs.ubifs -m 2048 -e 131072 -c 852 -r $PWD/rootfs/ rootfs.img
sudo ubinize -o rootfs.ubi -p 131072 -m 2048 -s 512 -O 512 ubi.ini
And it seems it creates the ubi image correctly, so I can put this ubi image on my uSD card into the root folder of the partition.
Into the u-boot (version 2014.10 (Feb 25 2015)) environment installaed on my gumstix overo board, this is the output of mtd command:
U-Boot 2014.10 (Feb 25 2015 - 07:02:26)

mtdparts: mtdparts=omap2-nand.0:512k(xloader),1792k(u-boot),256k(environ),8m(linux),-(rootfs)
Then I execute:
nand erase.part rootfs
load mmc 0:2 ${loadaddr} /rootfs.ubi
nand write ${loadaddr} rootfs ${filesize}
This sequence works fine for the gumstix-console-image-overo.ubi(with kernel image 3.17.8 armv71) that can be downloaded fromhttps://www.gumstix.com/software/software-downloads/ for yocto project, but does not work for my custom rootfs.ubi image, and the boot error is:

Bad Linux ARM zImage magic!
the zImage path into my rootfs.ubi filesystem is /boot/zImage, and the kernel I would like to install is a 2.6.34 armv71.
But I don't know where I am wrong.
Thank you in advance for your help.
Regards,
Simon

The installation process for software depends on your operating system and the program you are installing. As a result of these many combinations, we have created the steps below as a general guideline. The following does not cover errors during the installation process, as they are too vast for one document. Search on our site for further information on errors during the setup.
General tips
- Make sure your computer meets the system requirements of the program, game, or utility you are attempting to install.
- The manual or readme file contains exact instructions on how to install a program and are in the same directory as the installation files.
- When installing a program, utility, or game, it is always a good idea first to close or disable any other programs that are running.
- After installing a new program, if it prompts you to reboot the computer, do it.

How to install from a CD or DVD
Many software titles, games, and utilities have an AutoPlay feature. This feature automatically starts a setup screen for the software when the CD or DVD is inserted. If your program contains this feature, follow the steps that appear after inserting the disc into the computer.
Vodacom free airtime cheat codes. I purchased a v card from a 711 and cannot find a reference number as im trying to register the card. Where is this located on purchase voucher? How do i download the free pandora app on my kindle fire without putting in credit card, gift card, or any other card information? Free vodacom airtime codes. 
If AutoRun is disabled, or unavailable on your disc, follow these steps:
- Open My Computer.
- In the My Computer window, open the drive that contains the installation files. For example, if the files are on the CD-ROM drive, open the D: drive or letter of your CD-ROM drive.
- In the drive that contains your files, locate either the executablesetup (i.e. 'setup.exe') or install file. Double-clicking on this file starts the installation process. If there are multiple setup or install files, locate the executable file or double-click each setup or install file until you find the file that starts the installation.
Many times the icons associated with the installation files have the same name.
Install a CD on a computer with no disc drive
Some of the new computers may no longer have a disc drive. If your computer does not have a disc drive try installing what is on the CD from the Internet. Computer drivers, software for hardware devices, and some games and other programs are available for downloaded and can be installed from a download.
If the program is not available for download, copy all of the CD or DVD contents to another drive on another computer. For example, you could copy the contents of the disc to a USB flash drive and then install the program from the USB flash drive.
How to install from a Download
TipIf you need help with downloading a program see our how to download page.
- Download the program from the website providing the program.
- Open the download folder.
- If the file you downloaded is an executable file, double-click the file icon to start the setup process. If the downloaded file is compressed (e.g., .zip), you must extract the file's contents before setup can begin. Fortunately, this function is built into most versions of Windows.
- Once the files are extracted, double-click the setup to install.
How to install from a USB flash drive
- Open Windows Explorer or My Computer and find the USB drive that is often the last drive letter.
- Once the drive is opened find the setup or executable file, double-click the file icon to start the setup process.
Installing from MS-DOS or the Windows command line
Users installing a program from Microsoft DOS should have a basic understanding of the MS-DOS commands. If you are unfamiliar with any of the commands listed below, click the link to get additional information on that specific command.
- Before installing a program in MS-DOS, you must switch to the drive or directory that contains the installation files. If you are installing a program from a CD or diskette, switch to that drive. If the installation files are located in a different directory, use the dir command to list directories and the cd command to switch directories.
- Once you are in the directory or drive that contains the installation files, run the executable for setup. Many times this can be done by typing setup or install at the prompt to start the installation. If both of these commands give a bad command or file name error message, type dir *.exe or dir *.com or dir *.bat. These commands list any executable files found in the directory or drive. If any files are listed, execute these files to run the installation or setup of the program. If no files are listed when typing all three of the above commands, you're in the incorrect directory or drive letter for that program.
