```bash$ export YOCTO_DEPLOY_IMGS_DIR="<yocto-build-dir/tmp/deploy/images/foundation-v8>"```
```bash$ cd <path-to-Foundation_Platformpkg-dir/models/Linux64_GCC-X.X/>```
```
bash$ ./Foundation_Platform --cores=4 --no-sve --gicv3 \
         --data=${YOCTO_DEPLOY_IMGS_DIR}/bl1-fvp.bin@0x0 \
         --data=${YOCTO_DEPLOY_IMGS_DIR}/Image@0x80080000 \
         --data=${YOCTO_DEPLOY_IMGS_DIR}/foundation-v8-gicv3-psci.dtb@0x83000000 \
         --block-device=${YOCTO_DEPLOY_IMGS_DIR}/core-image-minimal-foundation-armv8.disk.img \
```

If you have built a configuration without a ramdisk, you can use the following
command in U-boot to start Linux:
```VExpress64# booti 0x80080000 - 0x83000000```
