裁剪对象:Linux内核的裁剪主要针对内核本身的功能和驱动程序;而U-Boot的裁剪更偏向于裁剪引导程序本身,以减小引导加载程序的体积和启动时间。 配置方式:Linux内核通常使用menuconfig等交互式配置工具进行裁剪,而U-Boot则通过修改.config文件或特定头文件进行配置。 启动流程:U-Boot在引导过程中负责初始化硬件、加载内核镜像...

当然我们可以使用更人性化的make menuconfig来配置u-boot,配置好后,就会在u-boot根目录下生成最新的.config文件,u-boot根据这些配置文件来决定该如何编译 u-boot源码,不多说了,继续往下分析。 GENERATED_GBL_DATA_SIZE在include/generated/generic-asm-offsets.h中定义为256,转换成十六进制为...
Trying to boot from MMC2MMC Device 1 not foundspl: could not find mmc device 1. error: -19SPL: failed to boot from all boot devices### ERROR ### Please RESET the board ### 我觉得原因是emmc是1c11000,uboot没有这个设备,自己下了好几个版本的uboot都没有这个设备,然后make menuconfig也...
More recently, U-Boot has added the Kbuild infrastructure used by the Linux kernel, allowing you to use the "make menuconfig" command to configure your build. Selection of Processor Architecture and Board Type: --- For all supported boards there are ready-to-use default configurations available...

使用u-boot 和 rootfs/initramfs 启动 Raspberry Pi 4B 0. 概述 这篇文章的目的是了解嵌入式Linux的四个组成部分 —— 工具链、引导加载程序、内核、根文件系统 —— 通过使用最少的代码从头开始启动 Raspberry Pi 4 的命令。 1. 硬件要求
i was successfully able to run menuconfig. I spent the last two days playing around with the settings and creating different patches. But somehow, i am not able to disable the console in u-boot. Every time i reboot i can stop the Rock-PI from booting, by spamming a connected serial con...

- should set up SDRAM, and anything needed to make the UART work - these is no need to clear BSS, it will be done by crt0.S - must return normally from this function (don't call board_init_r() directly) Here the BSS is cleared. For SPL, if CONFIG_SPL_STACK_R is defined...
