进行固化和更新的前提，uboot.imx、zImage、imx6ull.dtb和rootfs已经编译好，并且能成功启动和挂载。 在讲解imx6ull固化和更新uboot、zImage和dtb方法之前，先带大家了解一些imx6ull的分区情况以及各自的作用。

本文详细介绍了如何在Ubuntu环境下编译U-Boot，并通过MfgTool工具烧录到Linux开发板的EMMC中。 步骤包括上传和解压U-Boot源码、配置与编译，然后将编译后的uboot.imx文件下载到Windows并使用MfgTool进行OTG固化。 MfgTool的工作原理是先将文件下载到DDR中启动Linux，再烧写到EMMC。 最后，设置了网络环境变量和静态IP，以确保开发板能正常联网。 摘要：任何一个 linux 开发板都需要将 uboot、linux kernel、.dtb(设备树)和 rootfs 这四个文件烧写 …

Sep 4, 2022 · 本文介绍了如何在Ubuntu环境下利用dd命令将U-Boot烧写到SD卡中，用于开发板的U-Boot测试。 首先识别SD卡设备，然后使用dd命令烧写uboot-dtb.imx文件到指定设备。 烧录成功后，设置开发板为SD卡启动模式，并在启动时进入U-Boot命令行模式。 此外，还详细解析了U-boot.imx的SD卡烧录过程，包括IVT偏移量和加载数据长度等关键信息。 摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 > 在 Ubuntu 下可以更精细地操作 SD/TF 卡：可以把 …
