  • Clone meta-platform-xen repository in the same directory
   git clone https://github.com/qbeeukraine/meta-platform-xen.git -b 2.12/minimal
  • Initialize yocto build environment
   source poky/oe-init-build-env
  • Copy local.conf & bblayers.conf from supplied xen layer
   cp meta-platform-xen/meta-rcar-gen3-xen/docs/sample/conf/salvator-x/linaro-gcc/bsp/*.conf ./conf/
  • Build yocto
   bitbake core-image-minimal
  • Target images will be located in follow folder
   build/tmp/deploy/images/salvator-x-xen

BL2 & U-boot update procedure

Please reference to recent version of board manual for this procedure. Follow bootloaders should be updated:

  1. BL2 bootloader - from on we leave bootloaders in EL2 mode
  2. U-boot - don't disable SCIF clock & don't update memory nodes in DTS file

Check u-boot environment variables

Set follow configuration in u-boot command prompt. 

   bootargs=dom0_mem=512M console=dtuart dtuart=serial0 dom0_max_vcpus=1 bootscrub=0 flask_enforcing=1
   bootcmd=tftp 0x78080000 xen-salvator-x-xen.uImage; tftp 0x738000000 Image-r8a7795-salvator-x-dom0.dtb; tftp 0x7a000000 Image; tftp 0x7c000000 xenpolicy-salvator-x-xen; bootm 0x78080000 - 0x738000000
