+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 MMC using u-boot-spl +---------------------------

+Building +--------

+1. Add the RISC-V toolchain to your PATH. +2. Setup ARCH & cross compilation environment variable:

+.. code-block:: none

• export CROSS_COMPILE=<riscv64 toolchain prefix>

+3. make sifive_hifive_unmatched_fu740_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=generic 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 from MMC using U-Boot SPL +---------------------------------

+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=<path to opensbi/build/platform/generic/firmware/fw_dynamic.bin>
  

+Now build the U-Boot SPL and U-Boot proper

+.. code-block:: console

•   cd <U-Boot-dir>
  

•   make sifive_hifive_unmatched_fu740_defconfig
  

•   make
  

+This will generate spl/u-boot-spl.bin and FIT image (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

+U-Boot SPL expects a U-Boot FIT image (u-boot.itb) from a partition with GUID +type 2E54B353-1271-4842-806F-E436D6AF6985

+FIT image (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:: none

•   # sudo sgdisk --clear \
  

•   > --set-alignment=2 \
  

•   > --new=1:34:2081 --change-name=1:loader1 --typecode=1:5B193300-FC78-40CD-8002-E86C45580B47 \
  

•   > --new=2:2082:10273 --change-name=2:loader2 --typecode=2:2E54B353-1271-4842-806F-E436D6AF6985 \
  

•   > --new=3:10274: --change-name=3:rootfs --typecode=3:0FC63DAF-8483-4772-8E79-3D69D8477DE4 \
  

•   > /dev/sda
  

+Program the SD card

+.. code-block:: none

•   sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=34
  

•   sudo dd if=u-boot.itb of=/dev/sda seek=2082
  

+Booting +------- +Once you plugin the sdcard and power up, you should see the U-Boot prompt.
