+Running U-Boot SPL +------------------ +The U-Boot SPL will boot in M mode and load the FIT image which +include OpenSBI and U-Boot proper images. After loading progress, it +will jump to OpenSBI first and then U-Boot proper which will run in S mode.
+How to build U-Boot SPL +----------------------- +Before building U-Boot SPL, OpenSBI must be build first. OpenSBI can +be cloned and build for FU540 as below:
Please add .. code-block:: console
Will update in v3, thanks for catching this.
+git clone https://github.com/riscv/opensbi.git +cd opensbi +make PLATFORM=sifive/fu540
+Copy OpenSBI FW_DYNAMIC image +(build/platform/sifive/fu540/firmware/fw_dynamic.bin) +into U-Boot root directory
+How to build U-Boot SPL booting from MMC +---------------------------------------- +With sifive_fu540_spl_defconfig:
+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_spl_defconfig +4. make
+Flashing +--------
+The current U-Boot port is supported in S-mode only.
+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.
+First partition of the sdcard should contain "u-boot.itb" and +Partition type should be of "8300 Linux filesystem".
+.. code-block:: none
- sudo dd if=spl/u-boot-spl.bin of=/dev/disk2s4 bs=1024
- sudo dd if=u-boot.itb of=/dev/disk2s1 bs=1024
+Booting +------- +Once you plugin the sdcard and power up, you should see the U-Boot
prompt.
