  23. 				In u-boot: <code>make starfive_visionfive2_defconfig</code> then <code>make</code><br />
  24. 				If you want to configure how u-boot gets built, there is <code>make menuconfig</code>
  25. 			</p>
  27. 			<p>
  28. 				In OpenSBI, create &amp; execute a build script like this one, using u-boot as a payload for OpenSBI:
  29. 			</p>
  31. <pre><code><![CDATA[#!/bin/sh
  32. set -ex
  33. uboot_dir="${HOME}/Sources/source.denx.de/u-boot/u-boot/"
  34. uboot_bin="${uboot_dir}/u-boot.bin"
  35. uboot_dtb="${uboot_dir}/arch/riscv/dts/jh7110-starfive-visionfive-2.dtb"
  36. make PLATFORM=generic FW_PAYLOAD_PATH="${uboot_bin}" FW_FDT_PATH="${uboot_dtb}" FW_TEXT_START=0x40000000
  37. ]]></code></pre>
  39. 			<p>
  40. 				Then, back to u-boot:
  41. 				<ol>
  42. 					<li><code>wget https://github.com/starfive-tech/Tools/raw/0747c0510e090f69bf7d2884f44903b77b3db5c5/uboot_its/visionfive2-uboot-fit-image.its</code></li>
  43. 					<li><code>ln -s ~/Sources/github.com/riscv-software-src/opensbi//build/platform/generic/firmware/fw_payload.bin ./</code></li>
  44. 					<li><code>./tools/mkimage -f visionfive2-uboot-fit-image.its -A riscv -O u-boot -T firmware visionfive2_fw_payload.img</code></li>
  45. 				</ol>
  46. 			</p>
  48. 			<p>
  49. 				Finally, you can flash:
  50. 				<ol>
  51. 					<li><code>flashcp -v spl/u-boot-spl.bin.normal.out mtd:spl</code></li>
  52. 					<li><code>flashcp -v visionfive2_fw_payload.img mtd:uboot</code></li>
  53. 				</ol>
  54. 			</p>
  56. 			<h3>extlinux/extlinux.conf</h3>
  57. 			<p>
  58. 				No need to have anything flashed on SD/eMMC/NVMe like on x86-pc (MBR) or most other boards.
  59. 				U-Boot flashed on the bootchip will by default search for an <code>(/boot)/extlinux/extlinux.conf</code> file in a FAT or ext[34] filesystem.
  60. 				<br />
  61. 				See <a href="https://docs.u-boot.org/en/latest/develop/bootstd/overview.html">Standard Boot Overview - Das U-Boot documentation</a>
  62. 				and <a href="https://docs.u-boot.org/en/latest/develop/distro.html">Generic Distro Configuration Concept - Das U-Boot documentation</a>.
  63. 			</p>
  65. 			<p>
  66. 				For example with Alpine main system installed in a ZFS filesystem and <code>/boot</code> as ext4/fat/…:
