OpenSUSE JeOS bringup

Brief guide how to add target to openSUSE:Factory:ARM:JeOS

Get source code

• Install osc

  # zypper in osc

• Branch or copy openSUSE:Factory:ARM:JeOS project

  $ osc bco openSUSE:Factory:ARM JeOS

• Disable building of all images in your JeOS branch

Add new target

• Modify config.sh
  • Add contrib repo if required for downstream kernel/u-boot or addititional rpms (optional)
  • Add additional modules to include to initrd file (optional)

• Modify pre_checkin.sh
  • add target name to armv7_jeos_images, optional to armv7_gfx_images
    • jeos image contain only rootfs with main packages and gfx image also contain various desktop enviroments
• Modify Images.kiwi.in (input file for specific configs generation)
  • add target flavor #elif IS_FLAVOR_paz00

    +#elif IS_FLAVOR_paz00
    +#  define BOOTKERNEL default
    +#  define KERNEL_CMDLINE_SER "plymouth.enable=0 console=ttyS0,115200n8 console=tty"
    +#  define KERNEL_CMDLINE_GFX "plymouth.enable=0 console=ttyS0,115200n8 console=tty"
    +#  define EXTRA_PACKAGES PKG_BOOT_TAG(u-boot-paz00) \
    +                         PKG_BOOT_TAG(dtb-tegra2)
    

    • BOOTKERNEL var defines kernel name to use, for example default or lpae for upstream openSUSE Factory kernels
    • PKG_BOOT_TAG var defines u-boot rpm package name which contain board dtb file and name of rpm of u-boot itself for the board
  • add additional repo

    +#if IS_FLAVOR_paz00
    +        <repository type="rpm-md" priority="5">
    +                <source path="obs://devel:ARM:Factory:Contrib:Tegra/standard"/>
    +        </repository>
    +#endif
    

    • packages in higher priority repo will go before default factory repo ones
• Modify uboot-image-setup.in
  • add target case case $flavor in paz00)

    +  paz00)
    +    kerneladdr=0x1000000
    +    ramdiskaddr=0x2200000
    +    fdtaddr=0x2000000
    +    should_use_fdt=1
    +    should_load_fdt=1
    +    units="1 0"
    +    bootdevs="mmc usb"
    +    fdtfile=dtb/tegra20-paz00.dtb
    +    ;;
    

    • Define variables which openSUSE common boot.scr script will use
• Create uboot-setup-paz00.tgz
  • copy any of existing ones

    cp uboot-setup-panda.tgz uboot-setup-paz00.tgz

    • it will be overriten with pre_checkin.sh script

• run pre_checkin.sh to generate specific configs for all boards

  sh ./pre_checkin.sh

• run build of JeOS-paz00.kiwi

 osc build images armv7l JeOS-paz00.kiwi 

• Submit patch with new target to upstream Jeos project
