| 61 | I. Building the meta-nuc BSP layer | ||
| 62 | ========================================= | ||
| 63 | |||
| 64 | In order to build an image with BSP support for a given release, you | ||
| 65 | need to download the corresponding BSP tarball from the 'Board Support | ||
| 66 | Package (BSP) Downloads' page of the Yocto Project website. | ||
| 67 | |||
| 68 | Having done that, and assuming you extracted the BSP tarball contents | ||
| 69 | at the top-level of your yocto build tree, you can build a nuc | ||
| 70 | image by adding the location of the meta-nuc layer to | ||
| 71 | bblayers.conf, along with the meta-intel layer itself (to access | ||
| 72 | common metadata shared between BSPs) e.g.: | ||
| 73 | |||
| 74 | yocto/meta-intel \ | ||
| 75 | yocto/meta-intel/meta-nuc \ | ||
| 76 | |||
| 77 | To enable the nuc layer, add the nuc MACHINE to local.conf: | ||
| 78 | |||
| 79 | MACHINE ?= "nuc" | ||
| 80 | |||
| 81 | You should then be able to build a nuc image as such: | ||
| 82 | |||
| 83 | $ source oe-init-build-env | ||
| 84 | $ bitbake core-image-sato | ||
| 85 | |||
| 86 | At the end of a successful build, you should have a live image that | ||
| 87 | you can boot from a USB flash drive (see instructions on how to do | ||
| 88 | that below, in the section 'Booting the images from /binary'). | ||
| 89 | |||
| 90 | NOTE: The 'nuc' machine will include support for hardware video | ||
| 91 | acceleration via gstreamer if and only if the "commercial" string is | ||
| 92 | added to the the LICENSE_FLAGS_WHITELIST variable in your local.conf. | ||
| 93 | |||
| 94 | For example: | ||
| 95 | |||
| 96 | LICENSE_FLAGS_WHITELIST = "commercial" | ||
| 97 | |||
| 98 | The reason this is needed is to prevent the image from including | ||
| 99 | anything that might violate the license terms of the packages used to | ||
| 100 | implement the the video acceleration feature, such as gst-ffmpeg and | ||
| 101 | ffmpeg. As always, please consult the licenses included in the | ||
| 102 | specific packages for details if you use packages that require | ||
| 103 | particular LICENSE_FLAGS. | ||
| 104 | |||
| 105 | As an alternative to downloading the BSP tarball, you can also work | ||
| 106 | directly from the meta-intel git repository. For each BSP in the | ||
| 107 | 'meta-intel' repository, there are multiple branches, one | ||
| 108 | corresponding to each major release starting with 'laverne' (0.90), in | ||
| 109 | addition to the latest code which tracks the current master (note that | ||
| 110 | not all BSPs are present in every release). Instead of extracting a | ||
| 111 | BSP tarball at the top level of your yocto build tree, you can | ||
| 112 | equivalently check out the appropriate branch from the meta-intel | ||
| 113 | repository at the same location. | ||
| 114 | |||
| 115 | |||
| 116 | II. Booting the images in /binary | ||
| 117 | ================================= | ||
| 118 | |||
| 119 | This BSP contains bootable live images, which can be used to directly | ||
| 120 | boot Yocto off of a USB flash drive. | ||
| 121 | |||
| 122 | Under Linux, insert a USB flash drive. Assuming the USB flash drive | ||
| 123 | takes device /dev/sdf, use dd to copy the live image to it. For | ||
| 124 | example: | ||
| 125 | |||
| 126 | # dd if=core-image-sato-nuc-20101207053738.hddimg of=/dev/sdf | ||
| 127 | # sync | ||
| 128 | # eject /dev/sdf | ||
| 129 | |||
| 130 | This should give you a bootable USB flash device. Insert the device | ||
| 131 | into a bootable USB socket on the target, and power on. This should | ||
| 132 | result in a system booted to the Sato graphical desktop. | ||
| 133 | |||
| 134 | If you want a terminal, use the arrows at the top of the UI to move to | ||
| 135 | different pages of available applications, one of which is named | ||
| 136 | 'Terminal'. Clicking that should give you a root terminal. | ||
| 137 | |||
| 138 | If you want to ssh into the system, you can use the root terminal to | ||
| 139 | ifconfig the IP address and use that to ssh in. The root password is | ||
| 140 | empty, so to log in type 'root' for the user name and hit 'Enter' at | ||
| 141 | the Password prompt: and you should be in. | ||
| 142 | |||
| 143 | ---- | ||
| 144 | |||
| 145 | If you find you're getting corrupt images on the USB (it doesn't show | ||
| 146 | the syslinux boot: prompt, or the boot: prompt contains strange | ||
| 147 | characters), try doing this first: | ||
| 148 | |||
| 149 | # dd if=/dev/zero of=/dev/sdf bs=1M count=512 | ||
