.. SPDX-License-Identifier: GPL-2.0+ HiFive Unmatched ================ FU740-C000 RISC-V SoC --------------------- The FU740-C000 is a 4+1 64-bit RISC-V core SoC from SiFive. The HiFive Unmatched development platform is based on FU740-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. Booting from micro SD card using U-Boot SPL ------------------------------------------- Booting from an SD card requires that the boot mode selection DIP switches MSEL[3:0] are set to 1011. Building -------- Before building U-Boot SPL, OpenSBI must be built first. OpenSBI can be cloned and built for FU740 as below: .. code-block:: console git clone https://github.com/riscv/opensbi.git cd opensbi make PLATFORM=generic export OPENSBI= Now build the U-Boot SPL and U-Boot proper .. code-block:: console cd make sifive_unmatched_defconfig make This will generate spl/u-boot-spl.bin and u-boot.itb Flashing -------- ZSBL loads the U-Boot SPL (u-boot-spl.bin) from a partition with GUID type 5B193300-FC78-40CD-8002-E86C45580B47 With the default configuration U-Boot SPL expects u-boot.itb starting at sector 2082 (CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR=0x822). It is recommended to use a partition with type GUID 2E54B353-1271-4842-806F-E436D6AF6985 for storing main U-Boot. u-boot.itb is a combination of fw_dynamic.bin, u-boot-nodtb.bin and device tree blob (hifive-unmatched-a00.dtb) Format the SD card (make sure the disk has GPT, otherwise use gdisk to switch) .. code-block:: bash sudo sgdisk -g --clear -a 1 \ --new=1:34:2081 --change-name=1:spl --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \ --new=2:2082:10273 --change-name=2:uboot --typecode=2:2E54B353-1271-4842-806F-E436D6AF6985 \ --new=3:16384:282623 --change-name=3:boot --typecode=3:0x0700 \ --new=4:286720:13918207 --change-name=4:root --typecode=4:0x8300 \ /dev/sdX Copy linux Image.gz and hifive-unmatched-a00.dtb to boot partition .. code-block:: bash sudo mkfs.vfat /dev/sdX3 sudo mkfs.ext4 /dev/sdX4 sudo mount /dev/sdX3 /media/sdX3 sudo cp Image.gz hifive-unmatched-a00.dtb /media/sdX3/ Program the SD card .. code-block:: bash sudo dd if=spl/u-boot-spl.bin of=/dev/sdX seek=34 sudo dd if=u-boot.itb of=/dev/sdX seek=2082 Booting ------- Once you plugin the sdcard and power up, you should see the U-Boot prompt.
