This README file contains information on building the meta-romley BSP layer, and booting the images contained in the /binary directory. Please see the corresponding sections below for details. The romley platform consists of two versions: 1. romley - Sandy Bridge 2. romley - Ivy Bridge The romley - Sandy Bridge platform consists of the Intel Xeon E5-2600 and E5-2400 Series processors, plus the Intel C604/C602-J chipset (Sandy Bridge-EP/EN + Patsburg). The romley - Ivy Bridge platform consists of the Intel Xeon E5-2600 and E5-2400 v2 Series processors with the Intel C604/C602-J chipset (Ivy Bridge-EP/EN + Patsburg). This BSP assumes Matrox graphics is being used. Further information about the platforms supported by this BSP can be found here: http://www.intel.com/p/en_US/embedded/hwsw/hardware/xeon-e5-c604/overview Information on all Intel® embedded platforms can be found here: http://www.intel.com/p/en_US/embedded/hwsw/hardware Yocto Project Compatible ======================== This BSP is compatible with the Yocto Project as per the requirements listed here: https://www.yoctoproject.org/webform/yocto-project-compatible-registration Dependencies ============ This layer depends on: URI: git://git.openembedded.org/bitbake branch: master URI: git://git.openembedded.org/openembedded-core layers: meta branch: master URI: git://git.yoctoproject.org/meta-intel layers: intel branch: master Patches ======= Please submit any patches against this BSP to the Yocto mailing list (yocto@yoctoproject.org) and cc: the maintainer: Maintainer: Chan Wei Sern Please see the meta-intel/MAINTAINERS file for more details.

Building the meta-romley BSP layer ======================================= In order to build an image with BSP support for a given release, you need to download the corresponding BSP tarball from the 'Board Support Package (BSP) Downloads' page of the Yocto Project website. Having done that, and assuming you extracted the BSP tarball contents at the top-level of your yocto build tree, you can build a romley image by adding the location of the meta-romley layer to bblayers.conf, along with the meta-intel layer itself (to access common metadata shared between BSPs) e.g.: yocto/meta-intel \ yocto/meta-intel/meta-romley \ To enable the romley Sandy Bridge layer, add the romley MACHINE to local.conf: MACHINE ?= "romley" To enable the romley Ivy Bridge layer, add the romley-ivb MACHINE to local.conf: MACHINE ?= "romley-ivb" You should then be able to build a romley image as such: $ source oe-init-build-env $ bitbake core-image-sato At the end of a successful build, you should have a live image that you can boot from a USB flash drive (see instructions on how to do that below, in the section 'Booting the images from /binary'). As an alternative to downloading the BSP tarball, you can also work directly from the meta-intel git repository. For each BSP in the 'meta-intel' repository, there are multiple branches, one corresponding to each major release starting with 'laverne' (0.90), in addition to the latest code which tracks the current master (note that not all BSPs are present in every release). Instead of extracting a BSP tarball at the top level of your yocto build tree, you can equivalently check out the appropriate branch from the meta-intel repository at the same location. II. Booting the images in /binary ================================= This BSP contains bootable live images, which can be used to directly boot Yocto off of a USB flash drive. Under Linux, insert a USB flash drive. Assuming the USB flash drive takes device /dev/sdf, use dd to copy the live image to it. For example: # dd if=core-image-sato-romley.hddimg of=/dev/sdf # sync # eject /dev/sdf This should give you a bootable USB flash device. Insert the device into a bootable USB socket on the target, and power on. This should result in a system booted to the Sato graphical desktop. If you want a terminal, use the arrows at the top of the UI to move to different pages of available applications, one of which is named 'Terminal'. Clicking that should give you a root terminal. If you want to ssh into the system, you can use the root terminal to ifconfig the IP address and use that to ssh in. The root password is empty, so to log in type 'root' for the user name and hit 'Enter' at the Password prompt: and you should be in. If you're using Rose City and does not have ME firmware and struggling with rebooting the machine. This is because broken ME firmware can contribute to long wait of reboot. We have to changing the kernel command line to blacklist MEI driver to be loaded: 1. Open your syslinux in VI editor eg: # vi /media/sda/syslinux.cfg 2. Look for the line that has kernel command line which has certain similiarity as below: "APPEND initrd=/initrd LABEL=boot root=/dev/ram0 ....." or "APPEND initrd=/initrd LABEL=install root=/dev/ram0 ...." 3. Add "mei_me.blacklist=yes"at the end of that line and it will be like below: "APPEND inird=/initRD LABEL=boot root=/dev/ram0 .... mei_me.blacklist=yes" 4. Save this syslinux.cfg 5. Boot up the Romley with this new changed. III. Device Notes ================= a. Boot Loader -------------- - Support BIOS version at RoseCity board :RMLCRB.86J.R0.45.D018 b. I/O drivers -------------- -Support Matrox graphic card. -Support SATA, USB Host v2.0 -Supported I/O devices (APIC, RTC, SPI, UART, I2C, LPS, SMBus i801, WDT, and HPET) IV. Enabling Intel DPDK Technology =================================== There are recipes available for the 'Intel Data Plane Development Kit Technology components for use with this BSP. Please contact your Intel Field Sales Representative or visit Intel Embedded Design Center (www.intel.com/p/en_US/embedded/designcenter) for instructions on how to locate and use these recipes. ---- If you find you're getting corrupt images on the USB (it doesn't show the syslinux boot: prompt, or the boot: prompt contains strange characters), try doing this first: # dd if=/dev/zero of=/dev/sdf bs=1M count=512
