  21. 				In u-boot: <code>make starfive_visionfive2_defconfig</code> then <code>make</code><br />
  22. 				If you want to configure how u-boot gets built, there is <code>make menuconfig</code>
  23. 			</p>
  25. 			<p>
  26. 				In OpenSBI, create &amp; execute a build script like this one, using u-boot as a payload for OpenSBI:
  27. 			</p>
  29. <pre><code><![CDATA[#!/bin/sh
  30. set -ex
  31. uboot_dir="${HOME}/Sources/source.denx.de/u-boot/u-boot/"
  32. uboot_bin="${uboot_dir}/u-boot.bin"
  33. uboot_dtb="${uboot_dir}/arch/riscv/dts/jh7110-starfive-visionfive-2.dtb"
  34. make PLATFORM=generic FW_PAYLOAD_PATH="${uboot_bin}" FW_FDT_PATH="${uboot_dtb}" FW_TEXT_START=0x40000000
  35. ]]></code></pre>
  37. 			<p>
  38. 				Then, back to u-boot:
  39. 				<ol>
  40. 					<li><code>wget https://github.com/starfive-tech/Tools/raw/0747c0510e090f69bf7d2884f44903b77b3db5c5/uboot_its/visionfive2-uboot-fit-image.its</code></li>
  41. 					<li><code>ln -s ~/Sources/github.com/riscv-software-src/opensbi//build/platform/generic/firmware/fw_payload.bin ./</code></li>
  42. 					<li><code>./tools/mkimage -f visionfive2-uboot-fit-image.its -A riscv -O u-boot -T firmware visionfive2_fw_payload.img</code></li>
  43. 				</ol>
  44. 			</p>
  46. 			<p>
  47. 				Finally, you can flash:
  48. 				<ol>
  49. 					<li><code>flashcp -v spl/u-boot-spl.bin.normal.out mtd:spl</code></li>
  50. 					<li><code>flashcp -v visionfive2_fw_payload.img mtd:uboot</code></li>
  51. 				</ol>
  52. 			</p>
  54. 			<h3>extlinux.conf</h3>
  55. 			<p>
  56. 				No need to have it flashed as MBR like on x86, just have it present into a FAT or ext{3,4} filesystem, u-boot will then use it as configuration.
