+# Targets
+
+## Corstone-300
+
+The
+[Corstone-300](https://developer.arm.com/ip-products/subsystem/corstone/corstone-300)
+is a reference design of how to to build a secure System on Chip (SoC). A fixed
+virtual platform (FVP) of the Corstone-300 including the Arm Ethos-U can be
+downloaded from the Ecosystem page at
+[developer.arm.com](https://developer.arm.com/tools-and-software/open-source-software/arm-platforms-software/arm-ecosystem-fvps).
+
+### Building
+
+Building with default settings requires CMake for the configuration and make for
+building. This will produce an elf file which can be run on the FVP.
+
+```
+$ cmake -B build/corstone-300 targets/corstone-300
+$ make -C build/corstone-300
+```
+
+It is also possible to build with a different toolchain.
+
+```
+$ cmake -B build/corstone-300 targets/corstone-300 -DCMAKE_TOOLCHAIN_FILE=$PWD/cmake/toolchain/arm-none-eabi-gcc.cmake
+$ make -C build/corstone-300
+```
+
+### Testing
+
+Assuming that the Corstone-300 FVP has been downloaded, installed and placed in
+the PATH variable. Then the software binary can be tested like this.
+
+```
+$ FVP_Corstone_SSE-300_Ethos-U55 build/corstone-300/ethosu_corstone_300.elf
+```
