Get source code

• Install osc

  zypper in osc

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

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

• Modify Images.kiwi.in
  • 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

    +    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

  sh ./pre_checkin.sh

• run build of JeOS-paz00.kiwi
