| 41 | I. Building the meta-{{=machine}} BSP layer | ||
| 42 | ======================================== | ||
| 43 | |||
| 44 | --- replace with specific instructions for your layer --- | ||
| 45 | |||
| 46 | In order to build an image with BSP support for a given release, you | ||
| 47 | need to download the corresponding BSP tarball from the 'Board Support | ||
| 48 | Package (BSP) Downloads' page of the Yocto Project website. | ||
| 49 | |||
| 50 | Having done that, and assuming you extracted the BSP tarball contents | ||
| 51 | at the top-level of your yocto build tree, you can build a | ||
| 52 | {{=machine}} image by adding the location of the meta-{{=machine}} | ||
| 53 | layer to bblayers.conf, along with any other layers needed (to access | ||
| 54 | common metadata shared between BSPs) e.g.: | ||
| 55 | |||
| 56 | yocto/meta-xxxx \ | ||
| 57 | yocto/meta-xxxx/meta-{{=machine}} \ | ||
| 58 | |||
| 59 | To enable the {{=machine}} layer, add the {{=machine}} MACHINE to local.conf: | ||
| 60 | |||
| 61 | MACHINE ?= "{{=machine}}" | ||
| 62 | |||
| 63 | You should then be able to build a {{=machine}} image as such: | ||
| 64 | |||
| 65 | $ source oe-init-build-env | ||
| 66 | $ bitbake core-image-sato | ||
| 67 | |||
| 68 | At the end of a successful build, you should have a live image that | ||
| 69 | you can boot from a USB flash drive (see instructions on how to do | ||
| 70 | that below, in the section 'Booting the images from /binary'). | ||
| 71 | |||
| 72 | As an alternative to downloading the BSP tarball, you can also work | ||
| 73 | directly from the meta-xxxx git repository. For each BSP in the | ||
| 74 | 'meta-xxxx' repository, there are multiple branches, one corresponding | ||
| 75 | to each major release starting with 'laverne' (0.90), in addition to | ||
| 76 | the latest code which tracks the current master (note that not all | ||
| 77 | BSPs are present in every release). Instead of extracting a BSP | ||
| 78 | tarball at the top level of your yocto build tree, you can | ||
| 79 | equivalently check out the appropriate branch from the meta-xxxx | ||
| 80 | repository at the same location. | ||
| 81 | |||
| 82 | |||
| 83 | II. Booting the images in /binary | ||
| 84 | ================================= | ||
| 85 | |||
| 86 | --- replace with specific instructions for your platform --- | ||
| 87 | |||
| 88 | This BSP contains bootable live images, which can be used to directly | ||
| 89 | boot Yocto off of a USB flash drive. | ||
| 90 | |||
| 91 | Under Linux, insert a USB flash drive. Assuming the USB flash drive | ||
| 92 | takes device /dev/sdf, use dd to copy the live image to it. For | ||
| 93 | example: | ||
| 94 | |||
| 95 | # dd if=core-image-sato-{{=machine}}-20101207053738.hddimg of=/dev/sdf | ||
| 96 | # sync | ||
| 97 | # eject /dev/sdf | ||
| 98 | |||
| 99 | This should give you a bootable USB flash device. Insert the device | ||
| 100 | into a bootable USB socket on the target, and power on. This should | ||
| 101 | result in a system booted to the Sato graphical desktop. | ||
| 102 | |||
| 103 | If you want a terminal, use the arrows at the top of the UI to move to | ||
| 104 | different pages of available applications, one of which is named | ||
| 105 | 'Terminal'. Clicking that should give you a root terminal. | ||
| 106 | |||
| 107 | If you want to ssh into the system, you can use the root terminal to | ||
| 108 | ifconfig the IP address and use that to ssh in. The root password is | ||
| 109 | empty, so to log in type 'root' for the user name and hit 'Enter' at | ||
| 110 | the Password prompt: and you should be in. | ||
| 111 | |||
| 112 | ---- | ||
| 113 | |||
| 114 | If you find you're getting corrupt images on the USB (it doesn't show | ||
| 115 | the syslinux boot: prompt, or the boot: prompt contains strange | ||
| 116 | characters), try doing this first: | ||
| 117 | |||
| 118 | # dd if=/dev/zero of=/dev/sdf bs=1M count=512 | ||
