 First, one has to download the AArch64 software simulator from:
 
-  https://silver.arm.com/download/download.tm?pv=2663527
+  https://silver.arm.com/download/download.tm?pv=4807186
 
 Then, use the arm_foundationv8_defconfig configuration to build your
 Buildroot system.
 
 Finally, boot your system with:
 
- ${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/models/Linux64_GCC-4.7/Foundation_Platform \
+ ${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/models/Linux64_GCC-6.4/Foundation_Platform \
     --image output/images/linux-system.axf \
     --block-device output/images/rootfs.ext2 \
-    --network=nat
+    --network=nat \
+    --cores 4
 
 You can get network access from within the simulated environment
 by requesting an IP address using DHCP (run the command 'udhcpc').
