Ariane FPGA SoC Platform
|
|
========================
|
|
Ariane is a 6-stage, single issue, in-order CPU which implements the 64-bit
|
|
RISC-V instruction set. The Ariane FPGA development platform is based on FPGA
|
|
SoC (which currently supports only Genesys 2 board) and is capable of running
|
|
Linux.
|
|
|
|
The FPGA SoC currently contains the following peripherals:
|
|
- DDR3 memory controller
|
|
- SPI controller to conncet to an SDCard
|
|
- Ethernet controller
|
|
- JTAG port (see debugging section below)
|
|
- Bootrom containing zero stage bootloader and device tree.
|
|
|
|
To build platform specific library and firmwares, provide the
|
|
*PLATFORM=fpga/ariane* parameter to the top level `make` command.
|
|
|
|
Platform Options
|
|
----------------
|
|
|
|
The *Ariane FPGA* platform does not have any platform-specific options.

|
Building Ariane FPGA Platform
|
|
-----------------------------
|
|
|
|
**Linux Kernel Payload**
|
|
|
|
```
|
|
make PLATFORM=fpga/ariane FW_PAYLOAD_PATH=<linux_build_directory>/arch/riscv/boot/Image
|
|
```
|
|
|
|
Booting Ariane FPGA Platform
|
|
----------------------------
|
|
|
|
**Linux Kernel Payload**
|
|
|
|
As Linux kernel image is embedded in the OpenSBI firmware binary, Ariane will
|
|
directly boot into Linux directly after powered on.
