| # Build Software |
| |
| ## Prerequisites |
| |
| _Make sure you followed the install instructions to [prepare the system]({{< relref "install_instructions#system-preparation" >}}) and install the [compiler toolchain]({{< relref "install_instructions#compiler-toolchain" >}})._ |
| |
| ## Building software |
| |
| The following commands build the `boot_rom` and `hello_world` binaries: |
| |
| ```console |
| $ cd $REPO_TOP |
| $ make -C sw/device SW_DIR=boot_rom clean all |
| $ make -C sw/device SW_DIR=examples/hello_world clean all |
| ``` |
| |
| The build process produces a variety of output files. |
| |
| * `.elf`: the linked program in ELF format |
| * `.bin`: the linked program as plain binary |
| * `.dis`: the disassembled program |
| * `.vmem`: a Verilog memory file which can be read by `$readmemh()` in Verilog code |
| |
| Please see [SW build flow]("/sw/device/doc/sw_build_flow.md") for more details. |
