Atish Patra75a90392019-02-25 08:15:27 +0000[diff] [blame^]1FU540-C000 RISC-V SoC
2=====================
3The FU540-C000 is the world’s first 4+1 64-bit RISC‑V SoC from SiFive.
4
5The HiFive Unleashed development platform is based on FU540-C000 and capable
6of running Linux.
7
8Mainline support
9================
10The support for following drivers are already enabled:
111. SiFive UART Driver.
122. SiFive PRCI Driver for clock.
133. Cadence MACB ethernet driver for networking support.
14
15TODO:
161. SPI driver is still missing. So MMC card can't be used in U-Boot as of now.
172. U-Boot expects the serial console device entry to be present under /chosen
18 DT node. Example:
19 chosen {
20 stdout-path = "/soc/serial@10010000:115200";
21 };
22
23 Without a serial console U-Boot will panic.
24
25Building
26========
271. Add the RISC-V toolchain to your PATH.
282. Setup ARCH & cross compilation enviornment variable.
29 a. export ARCH=riscv
30 b. export CROSS_COMPILE=<riscv64 toolchain prefix>
313. make sifive_fu540_defconfig
324. make
33
34Flashing
35========
36The current U-Boot port is supported in S-mode only and loaded from DRAM.
37
38A prior stage (M-mode) firmware/bootloader (e.g OpenSBI or BBL) is required to
39load the u-boot.bin into memory and provide runtime services. The u-boot.bin
40can be given as a payload to the prior stage (M-mode) firmware/bootloader.
41
42The description of steps required to build the firmware is beyond the scope of
43this document. Please refer OpenSBI or BBL documenation.
44(Note: OpenSBI git repo is at https://github.com/riscv/opensbi.git)
45(Note: BBL git repo is at https://github.com/riscv/riscv-pk.git)
46
47Once the prior stage firmware/bootloader binary is generated, it should be
48copied to the first partition of the sdcard.
49
50sudo dd if=<prior_stage_firmware_binary> of=/dev/disk2s1 bs=1024
51
52Booting
53=======
54Once you plugin the sdcard and power up, you should see the U-Boot prompt.
