基于 i.MX Yocto 官方文档生成的镜像怎么启动

ming_lo

根据 NXP 的文档 https://www.nxp.com.cn/docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf
生成了 core-image-base-imx8mm-ddr4-evk.wic.bz2，并 flash 到 TF 卡上。
启动时一直打不到 Block device。请问，还有哪里需要改？

建议您直接用我们所提供的uboot镜像，是直接可以用的

你是指只用你们提供的 uboot 还是指包含 rootfs 的整个镜像？

如果是指整个镜像，因为我们只想保留需要的软件并加入几个第三方应用，基于你们镜像要怎么做？有自动化的工具还是只能手工删和添加？

如果是指 整合你们的 uboot，请问有没有文档说明怎么和yocto 的流程整合，可以只用不他们的uboot，而指定用你们提供的？

我指的是uboot镜像——flash_sd_emmc.bin，没有相关的文档说明
