- HiFive Unleashed
- ================
- FU540-C000 RISC-V SoC
- ---------------------
- The FU540-C000 is the world’s first 4+1 64-bit RISC-V SoC from SiFive.
- The HiFive Unleashed development platform is based on FU540-C000 and capable
- of running Linux.
- Mainline support
- ----------------
- The support for following drivers are already enabled:
- 1. SiFive UART Driver.
- 2. SiFive PRCI Driver for clock.
- 3. Cadence MACB ethernet driver for networking support.
- 4. SiFive SPI Driver.
- 5. MMC SPI Driver for MMC/SD support.
- TODO:
- 1. U-Boot expects the serial console device entry to be present under /chosen
- DT node. Without a serial console U-Boot will panic. Example:
- .. code-block:: none
- chosen {
- stdout-path = "/soc/serial@10010000:115200";
- };
- Building
- --------
- 1. Add the RISC-V toolchain to your PATH.
- 2. Setup ARCH & cross compilation enviornment variable:
- .. code-block:: none
- export ARCH=riscv
- export CROSS_COMPILE=<riscv64 toolchain prefix>
- 3. make sifive_fu540_defconfig
- 4. make
- Flashing
- --------
- The current U-Boot port is supported in S-mode only and loaded from DRAM.
- A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
- boot the u-boot.bin in S-mode and provide M-mode runtime services.
- Currently, the u-boot.bin is used as a payload of the OpenSBI FW_PAYLOAD
- firmware. We need to compile OpenSBI with below command:
- .. code-block:: none
- make PLATFORM=sifive/fu540 FW_PAYLOAD_PATH=<path to u-boot-dtb.bin>
- More detailed description of steps required to build FW_PAYLOAD firmware
- is beyond the scope of this document. Please refer OpenSBI documenation.
- (Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
- Once the prior stage firmware/bootloader binary is generated, it should be
- copied to the first partition of the sdcard.
- .. code-block:: none
- sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024
- Booting
- -------
- Once you plugin the sdcard and power up, you should see the U-Boot prompt.
