Regardless of what I do after my FSBL and u-boot, it boots the Linux that came on the board from Avnet. The build date of the FSBL and the FPGA lights shows me it's using my SD card (formated with 4mb empty before and 2 partitions; fat32 and ext4), but then loads the pre-bu...
之前介绍过用Qemu模拟运行uboot,然后从网络启动linux(用Qemu模拟vexpress-a9 (三)--- 实现用u-boot引导Linux内核),下面介绍用Qemu运行uboot,然后将存放在虚拟出来的SD卡里加载linux kernel、设备树,并运行。 一、编译uboot 下载最新的uboot,编译vexpress-a9: makeARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-vexpres...

SD 卡将用于存储引导加载程序和根文件。所以,我们首先在其上创建两个分区 - boot(FAT32格式)和 root(ext4格式)。 2.1 查找TF卡设备名 将SD 读卡器插入 Linux PC 后,从dmesg或mount找到其设备名称。 $ dmesg |tail[19304.704047] usbcore: registered new interface driver uas ...
1.2、重新编译linux内核,实现bootargs传递分区信息 E2000配置从MMC(eMMC/SD卡)启动的模式,上电启动需要从MMC设备(eMMC/SD卡)起始地址加载BIOS固件,BIOS固件会覆盖分区表信息,因此需要开启“u-boot通过bootargs重新传递分区表”的功能。 在交叉编译环境(Ubuntu20.04_X86虚拟机),进入linux kernel源码目录,运行make menuconf...
Initially i used a custom board for imx6ul and successfully able to boot from SD card for Linux 3.14. Now, I am using the same custom board for imx6ull, with just changing the processor. I figured out that both imx6ul and imx6ull are pin to pin compatible. So I guess its...
嵌入式Linux开发-uboot常用命令介绍(下篇) 1. 前言 这篇文章是UBOOT命令介绍的下篇,接着上篇文章介绍剩下的几个命令用法。 主要是涉及的命令是:磁盘分区、磁盘文件加载、内核引导、二进制文件加载、跳转命令、磁盘文件系统格式等等。 2. UBOOT命令 2.1 fatls –列出指定目录下的文件...
I am trying to restore an Allwinner A13 based OEM board to working condition, because the original SD card died and there is currently no way to get an original backup image. Only thing I have so far is the linux rootfs and a partition table it wants to use (The original sizes and fi...
