8 The FU540-C000 is the world’s first 4+1 64-bit RISC-V SoC from SiFive.
10 The HiFive Unleashed development platform is based on FU540-C000 and capable
15 The support for following drivers are already enabled:
17 1. SiFive UART Driver.
18 2. SiFive PRCI Driver for clock.
19 3. Cadence MACB ethernet driver for networking support.
21 5. MMC SPI Driver for MMC/SD support.
25 1. U-Boot expects the serial console device entry to be present under /chosen
26 DT node. Without a serial console U-Boot will panic. Example:
31 stdout-path = "/soc/serial@10010000:115200";
37 1. Add the RISC-V toolchain to your PATH.
38 2. Setup ARCH & cross compilation enviornment variable:
43 export CROSS_COMPILE=<riscv64 toolchain prefix>
45 3. make sifive_fu540_defconfig
51 The current U-Boot port is supported in S-mode only and loaded from DRAM.
53 A prior stage M-mode firmware/bootloader (e.g OpenSBI) is required to
54 boot the u-boot.bin in S-mode and provide M-mode runtime services.
56 Currently, the u-boot.bin is used as a payload of the OpenSBI FW_PAYLOAD
57 firmware. We need to compile OpenSBI with below command:
61 make PLATFORM=sifive/fu540 FW_PAYLOAD_PATH=<path to u-boot-dtb.bin>
63 More detailed description of steps required to build FW_PAYLOAD firmware
64 is beyond the scope of this document. Please refer OpenSBI documenation.
65 (Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
67 Once the prior stage firmware/bootloader binary is generated, it should be
68 copied to the first partition of the sdcard.
72 sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024
76 Once you plugin the sdcard and power up, you should see the U-Boot prompt.
