| 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.bin> FW_PAYLOAD_FDT_PATH=<path to hifive-unleashed-a00.dtb from Linux> |
| |
| (Note: Prefer hifive-unleashed-a00.dtb from Linux-5.3 or higher) |
| (Note: Linux-5.2 is also fine but it does not have ethernet DT node) |
| |
| 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. |
