SiFive HiFive1¶
Overview¶
The HiFive1 is an Arduino-compatible development board with an FE310 RISC-V SoC. More information can be found on SiFive’s website.
Programming and debugging¶
Building¶
Applications for the hifive1 board configuration can be built as usual
(see Build an Application) using the corresponding board name:
# On Linux/macOS
mkdir build && cd build
# On Windows
mkdir build & cd build
# Use cmake to configure a Ninja-based build system:
cmake -GNinja -DBOARD=hifive1 ..
# Now run ninja on the generated build system:
ninja
Flashing¶
In order to upload the application to the device, you’ll need OpenOCD with RISC-V support. Download the tarball for your OS from the SiFive website and extract it.
The Zephyr SDK uses a bundled version of OpenOCD by default. You can
overwrite that behavior by adding the
-DOPENOCD=<path/to/riscv-openocd/bin/openocd> parameter when building:
# On Linux/macOS
mkdir build && cd build
# On Windows
mkdir build & cd build
# Use cmake to configure a Ninja-based build system:
cmake -GNinja -DBOARD=hifive1 -DOPENOCD=<path/to/riscv-openocd/bin/openocd> ..
# Now run ninja on the generated build system:
ninja
When using a custom toolchain it should be enough to have the downloaded
version of the binary in your PATH.
Now you can flash the application as usual (see Build an Application and Run an Application for more details):
ninja flash
Depending on your OS you might have to run the flash command as superuser.
