== Bootloader == |

For ARM64 Xen requires to be booted in EL2 mode by the bootloader. |
|||
By default Rockchip RK3399 Ibox3399 development board comes with u-boot which is not very friendly for booting Xen. |
|||
Please update the u-boot with provided by Rockchip [https://github.com/rockchip-linux/u-boot rockchip-linux/u-boot github]. |
|||
Build instructions: [https://github.com/rockchip-linux/u-boot/blob/release/board/rockchip/evb_rk3399/README rockchip-linux/u-boot github README]. |

Get Xen and switch to xen-4.10.1 tag: |
|||
git clone git://xenbits.xen.org/xen.git |
|||
cd xen |
|||
git checkout RELEASE-4.10.1 -b 'xen-rk3399' |
|||
Enable earlyprintk configuration for rk3399 boards: |
|||
diff --git a/xen/arch/arm/Rules.mk b/xen/arch/arm/Rules.mk |

Configure Hypervisor: |

export PATH=$PATH:<path_to_gcc-linaro>/bin/ |

make menuconfig CROSS_COMPILE=aarch64-linux-gnu- XEN_TARGET_ARCH=arm64 |

cd ../ |

make dist-xen CROSS_COMPILE=aarch64-linux-gnu- XEN_TARGET_ARCH=arm64 debug=y CONFIG_EARLY_PRINTK=rk3399 |
|||
Make image suitable to be booted by u-boot: |
|||
mkimage -A arm64 -T kernel -a 0x02000000 -e 0x02000000 -C none -d ./xen/xen xen4.10-uImage |
|||
Collect xen4.10-uImage file at this step. |
