Poky Hardware README
====================
This file gives details about using Poky with the reference machines
supported out of the box. A full list of supported reference target machines
can be found by looking in the following directories:
meta/conf/machine/
meta-yocto-bsp/conf/machine/
If you are in doubt about using Poky/OpenEmbedded with your hardware, consult
the documentation for your board/device.
Support for additional devices is normally added by creating BSP layers - for
more information please see the Yocto Board Support Package (BSP) Developer's
Guide - documentation source is in documentation/bspguide or download the PDF
from:
http://yoctoproject.org/documentation
Support for physical reference hardware has now been split out into a
meta-yocto-bsp layer which can be removed separately from other layers if not
needed.
QEMU Emulation Targets
======================
To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported:
* ARM (qemuarm)
* x86 (qemux86)
* x86-64 (qemux86-64)
* PowerPC (qemuppc)
* MIPS (qemumips)
Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
Hardware Reference Boards
=========================
The following boards are supported by the meta-yocto-bsp layer:
* Texas Instruments Beaglebone (beaglebone)
* Freescale MPC8315E-RDB (mpc8315e-rdb)
For more information see the board's section below. The appropriate MACHINE
variable value corresponding to the board is given in brackets.
Reference Board Maintenance
===========================

and is likely to work on many unlisted Atom/Core/Xeon based devices. The MACHINE
type supports ethernet, wifi, sound, and Intel/vesa graphics by default in
addition to common PC input devices, busses, and so on. Note that it does not
included the binary-only graphic drivers used on some Atom platforms, for
accelerated graphics on these machines please refer to meta-intel.
Depending on the device, it can boot from a traditional hard-disk, a USB device,
or over the network. Writing generated images to physical media is
straightforward with a caveat for USB devices. The following examples assume the
target boot device is /dev/sdb, be sure to verify this and use the correct
device as the following commands are run as root and are not reversable.
USB Device:
1. Build a live image. This image type consists of a simple filesystem
without a partition table, which is suitable for USB keys, and with the
default setup for the genericx86 machine, this image type is built
automatically for any image you build. For example:
$ bitbake core-image-minimal
2. Use the "dd" utility to write the image to the raw block device. For
example:
# dd if=core-image-minimal-genericx86.hddimg of=/dev/sdb
If the device fails to boot with "Boot error" displayed, or apparently
stops just after the SYSLINUX version banner, it is likely the BIOS cannot
understand the physical layout of the disk (or rather it expects a
particular layout and cannot handle anything else). There are two possible
solutions to this problem:
1. Change the BIOS USB Device setting to HDD mode. The label will vary by
device, but the idea is to force BIOS to read the Cylinder/Head/Sector
geometry from the device.
2. Without such an option, the BIOS generally boots the device in USB-ZIP
mode. To write an image to a USB device that will be bootable in
USB-ZIP mode, carry out the following actions:
a. Determine the geometry of your USB device using fdisk:
# fdisk /dev/sdb
Command (m for help): p
Disk /dev/sdb: 4011 MB, 4011491328 bytes
124 heads, 62 sectors/track, 1019 cylinders, total 7834944 sectors
...
Command (m for help): q
b. Configure the USB device for USB-ZIP mode:
# mkdiskimage -4 /dev/sdb 1019 124 62
Where 1019, 124 and 62 are the cylinder, head and sectors/track counts
as reported by fdisk (substitute the values reported for your device).
When the operation has finished and the access LED (if any) on the
device stops flashing, remove and reinsert the device to allow the
kernel to detect the new partition layout.
c. Copy the contents of the image to the USB-ZIP mode device:
# mkdir /tmp/image
# mkdir /tmp/usbkey
# mount -o loop core-image-minimal-genericx86.hddimg /tmp/image
# mount /dev/sdb4 /tmp/usbkey
# cp -rf /tmp/image/* /tmp/usbkey
d. Install the syslinux boot loader:
# syslinux /dev/sdb4
e. Unmount everything:
# umount /tmp/image
# umount /tmp/usbkey
Install the boot device in the target board and configure the BIOS to boot
from it.
For more details on the USB-ZIP scenario, see the syslinux documentation:
http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=blob_plain;f=doc/usbkey.txt;hb=HEAD
Texas Instruments Beaglebone (beaglebone)
=========================================
The Beaglebone is an ARM Cortex-A8 development board with USB, Ethernet, 2D/3D
accelerated graphics, audio, serial, JTAG, and SD/MMC. The Black adds a faster
CPU, more RAM, eMMC flash and a micro HDMI port. The beaglebone MACHINE is
tested on the following platforms:
o Beaglebone Black A6
o Beaglebone A6 (the original "White" model)
The Beaglebone Black has eMMC, while the White does not. Pressing the USER/BOOT
button when powering on will temporarily change the boot order. But for the sake
of simplicity, these instructions assume you have erased the eMMC on the Black,
so its boot behavior matches that of the White and boots off of SD card. To do
this, issue the following commands from the u-boot prompt:
# mmc dev 1
# mmc erase 0 512
To further tailor these instructions for your board, please refer to the
documentation at http://www.beagleboard.org/bone and http://www.beagleboard.org/black
From a Linux system with access to the image files perform the following steps
as root, replacing mmcblk0* with the SD card device on your machine (such as sdc
if used via a usb card reader):
1. Partition and format an SD card:
# fdisk -lu /dev/mmcblk0
Disk /dev/mmcblk0: 3951 MB, 3951034368 bytes
255 heads, 63 sectors/track, 480 cylinders, total 7716864 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 63 144584 72261 c Win95 FAT32 (LBA)
/dev/mmcblk0p2 144585 465884 160650 83 Linux
# mkfs.vfat -F 16 -n "boot" /dev/mmcblk0p1
# mke2fs -j -L "root" /dev/mmcblk0p2
The following assumes the SD card partitions 1 and 2 are mounted at
/media/boot and /media/root respectively. Removing the card and reinserting
it will do just that on most modern Linux desktop environments.
The files referenced below are made available after the build in
build/tmp/deploy/images.
2. Install the boot loaders
# cp MLO-beaglebone /media/boot/MLO
# cp u-boot-beaglebone.img /media/boot/u-boot.img
3. Install the root filesystem
# tar x -C /media/root -f core-image-$IMAGE_TYPE-beaglebone.tar.bz2
4. If using core-image-base or core-image-sato images, the SD card is ready
and rootfs already contains the kernel, modules and device tree (DTB)
files necessary to be booted with U-boot's default configuration, so
skip directly to step 8.
For core-image-minimal, proceed through next steps.
5. If using core-image-minimal rootfs, install the modules
# tar x -C /media/root -f modules-beaglebone.tgz
6. If using core-image-minimal rootfs, install the kernel zImage into /boot
directory of rootfs
# cp zImage-beaglebone.bin /media/root/boot/zImage
7. If using core-image-minimal rootfs, also install device tree (DTB) files
into /boot directory of rootfs
# cp zImage-am335x-bone.dtb /media/root/boot/am335x-bone.dtb
# cp zImage-am335x-boneblack.dtb /media/root/boot/am335x-boneblack.dtb
8. Unmount the SD partitions, insert the SD card into the Beaglebone, and
boot the Beaglebone
Freescale MPC8315E-RDB (mpc8315e-rdb)
=====================================
The MPC8315 PowerPC reference platform (MPC8315E-RDB) is aimed at hardware and
software development of network attached storage (NAS) and digital media server
applications. The MPC8315E-RDB features the PowerQUICC II Pro processor, which
includes a built-in security accelerator.
(Note: you may find it easier to order MPC8315E-RDBA; this appears to be the
same board in an enclosure with accessories. In any case it is fully
compatible with the instructions given here.)
Setup instructions
------------------
You will need the following:
* NFS root setup on your workstation
* TFTP server installed on your workstation
* Straight-thru 9-conductor serial cable (DB9, M/F) connected from your
PC to UART1
* Ethernet connected to the first ethernet port on the board
--- Preparation ---
Note: if you have altered your board's ethernet MAC address(es) from the
defaults, or you need to do so because you want multiple boards on the same
network, then you will need to change the values in the dts file (patch
linux/arch/powerpc/boot/dts/mpc8315erdb.dts within the kernel source). If
you have left them at the factory default then you shouldn't need to do
anything here.
--- Booting from NFS root ---
Load the kernel and dtb (device tree blob), and boot the system as follows:
1. Get the kernel (uImage-mpc8315e-rdb.bin) and dtb (uImage-mpc8315e-rdb.dtb)
files from the tmp/deploy directory, and make them available on your TFTP
server.
2. Connect the board's first serial port to your workstation and then start up
your favourite serial terminal so that you will be able to interact with
the serial console. If you don't have a favourite, picocom is suggested:
$ picocom /dev/ttyUSB0 -b 115200
3. Power up or reset the board and press a key on the terminal when prompted
to get to the U-Boot command line
4. Set up the environment in U-Boot:
=> setenv ipaddr <board ip>
=> setenv serverip <tftp server ip>
=> setenv bootargs root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:255.255.255.0:mpc8315e:eth0:off console=ttyS0,115200
5. Download the kernel and dtb, and boot:
=> tftp 1000000 uImage-mpc8315e-rdb.bin
=> tftp 2000000 uImage-mpc8315e-rdb.dtb
=> bootm 1000000 - 2000000
--- Booting from JFFS2 root ---
1. First boot the board with NFS root.
2. Erase the MTD partition which will be used as root:
$ flash_eraseall /dev/mtd3
3. Copy the JFFS2 image to the MTD partition:
$ flashcp core-image-minimal-mpc8315e-rdb.jffs2 /dev/mtd3
4. Then reboot the board and set up the environment in U-Boot:
=> setenv bootargs root=/dev/mtdblock3 rootfstype=jffs2 console=ttyS0,115200
Ubiquiti Networks EdgeRouter Lite (edgerouter)
==============================================
The EdgeRouter Lite is part of the EdgeMax series. It is a MIPS64 router
(based on the Cavium Octeon processor) with 512MB of RAM, which uses an
internal USB pendrive for storage.
Setup instructions
------------------
You will need the following:
* RJ45 -> serial ("rollover") cable connected from your PC to the CONSOLE
port on the device
* Ethernet connected to the first ethernet port on the board
If using NFS as part of the setup process, you will also need:
* NFS root setup on your workstation
* TFTP server installed on your workstation (if fetching the kernel from
TFTP, see below).
--- Preparation ---
Build an image (e.g. core-image-minimal) using "edgerouter" as the MACHINE.
In the following instruction it is based on core-image-minimal. Another target
may be similiar with it.
--- Booting from NFS root / kernel via TFTP ---
Load the kernel, and boot the system as follows:
1. Get the kernel (vmlinux) file from the tmp/deploy/images/edgerouter
directory, and make them available on your TFTP server.
2. Connect the board's first serial port to your workstation and then start up
your favourite serial terminal so that you will be able to interact with
the serial console. If you don't have a favourite, picocom is suggested:
$ picocom /dev/ttyS0 -b 115200
3. Power up or reset the board and press a key on the terminal when prompted
to get to the U-Boot command line
4. Set up the environment in U-Boot:
=> setenv ipaddr <board ip>
=> setenv serverip <tftp server ip>
5. Download the kernel and boot:
=> tftp tftp $loadaddr vmlinux
=> bootoctlinux $loadaddr coremask=0x3 root=/dev/nfs rw nfsroot=<nfsroot ip>:<rootfs path> ip=<board ip>:<server ip>:<gateway ip>:<netmask>:edgerouter:eth0:off mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
--- Booting from USB root ---
To boot from the USB disk, you either need to remove it from the edgerouter
box and populate it from another computer, or use a previously booted NFS
image and populate from the edgerouter itself.
Type 1: Mounted USB disk
------------------------
To boot from the USB disk there are two available partitions on the factory
USB storage. The rest of this guide assumes that these partitions are left
intact. If you change the partition scheme, you must update your boot method
appropriately.
The standard partitions are:
- 1: vfat partition containing factory kernels
- 2: ext3 partition for the root filesystem.
You can place the kernel on either partition 1, or partition 2, but the roofs
must go on partition 2 (due to its size).
Note: If you place the kernel on the ext3 partition, you must re-create the
ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
cannot read the partition otherwise.
Steps:
1. Remove the USB disk from the edgerouter and insert it into a computer
that has access to your build artifacts.
2. Copy the kernel image to the USB storage (assuming discovered as 'sdb' on
the development machine):
2a) if booting from vfat
# mount /dev/sdb1 /mnt
# cp tmp/deploy/images/edgerouter/vmlinux /mnt
# umount /mnt
2b) if booting from ext3
# mkfs.ext3 -I 128 /dev/sdb2
# mount /dev/sdb2 /mnt
# mkdir /mnt/boot
# cp tmp/deploy/images/edgerouter/vmlinux /mnt/boot
# umount /mnt
3. Extract the rootfs to the USB storage ext3 partition
# mount /dev/sdb2 /mnt
# tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /mnt
# umount /mnt
4. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
command line:
5. Load the kernel and boot:
5a) vfat boot
=> fatload usb 0:1 $loadaddr vmlinux
5b) ext3 boot
=> ext2load usb 0:2 $loadaddr boot/vmlinux
=> bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
Type 2: NFS
-----------
Note: If you place the kernel on the ext3 partition, you must re-create the
ext3 filesystem, since the factory u-boot can only handle 128 byte inodes and
cannot read the partition otherwise.
These boot instructions assume that you have recreated the ext3 filesystem with
128 byte inodes, you have an updated uboot or you are running and image capable
of making the filesystem on the board itself.
1. Boot from NFS root
2. Mount the USB disk partition 2 and then extract the contents of
tmp/deploy/core-image-XXXX.tar.bz2 into it.
Before starting, copy core-image-minimal-xxx.tar.bz2 and vmlinux into
rootfs path on your workstation.
and then,
# mount /dev/sda2 /media/sda2
# tar -xvjpf core-image-minimal-XXX.tar.bz2 -C /media/sda2
# cp vmlinux /media/sda2/boot/vmlinux
# umount /media/sda2
# reboot
3. Reboot the board and press a key on the terminal when prompted to get to the U-Boot
command line:
# reboot
4. Load the kernel and boot:
=> ext2load usb 0:2 $loadaddr boot/vmlinux
=> bootoctlinux $loadaddr coremask=0x3 root=/dev/sda2 rw rootwait mtdparts=phys_mapped_flash:512k(boot0),512k(boot1),64k@3072k(eeprom)
