The appropriate MACHINE -variable value corresponding to the device is given in brackets. - - - - Specific Hardware Documentation - =============================== - - -Intel x86 based PCs and devices (genericx86*) -============================================= - -The genericx86 and genericx86-64 MACHINE are tested on the following platforms: - -Intel Xeon/Core i-Series: - + Intel NUC5 Series - ix-52xx Series SOC (Broadwell) - + Intel NUC6 Series - ix-62xx Series SOC (Skylake) - + Intel Shumway Xeon Server - -Intel Atom platforms: - + MinnowBoard MAX - E3825 SOC (Bay Trail) - + MinnowBoard MAX - Turbot (ADI Engineering) - E3826 SOC (Bay Trail) - - These boards can be either 32bot or 64bit modes depending on firmware - - See minnowboard.org for details - + Intel Braswell SOC - -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. - -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. Use a ".wic" image with an EFI partition - - a) With a default grub-efi bootloader: - # dd if=core-image-minimal-genericx86-64.wic of=/dev/sdb - - b) Use systemd-boot instead - - Build an image with EFI_PROVIDER="systemd-boot" then use the above - dd command to write the image to a USB stick. - - -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: - - 1. Build an image. For example: - - $ bitbake core-image-minimal - - 2. Use the "dd" utility to write the image to the SD card. For example: - - # dd core-image-minimal-beaglebone.wic of=/dev/sdb - - 3. Insert the SD card into the Beaglebone and boot the board. - -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. - -Note: To boot from USB disk you need u-boot that supports 'ext2load usb' -command. You need to setup TFTP server, load u-boot from there and -flash it to NOR flash. - -Beware! Flashing bootloader is potentially dangerous operation that can -brick your device if done incorrectly. Please, make sure you understand -what below commands mean before executing them. - -Load the new u-boot.bin from TFTP server to memory address 200000 -=> tftp 200000 u-boot.bin - -Disable flash protection -=> protect off all - -Erase the old u-boot from fe000000 to fe06ffff in NOR flash. -The size is 0x70000 (458752 bytes) -=> erase fe000000 fe06ffff - -Copy the new u-boot from address 200000 to fe000000 -the size is 0x70000. It has to be greater or equal to u-boot.bin size -=> cp.b 200000 fe000000 70000 - -Enable flash protection again -=> protect on all - -Reset the board -=> reset - ---- Booting from USB disk --- - - 1.

Remove the USB disk from the edgerouter and insert it into a computer - that has access to your build artifacts. - - 2. Flash the image. - - # dd if=core-image-minimal-edgerouter.wic of=/dev/sdb - - 3. Insert USB disk into the edgerouter and boot it. - -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.
