2、E20000Q-DEMO SD卡启动BIOS和系统2.1、制作SD启动系统盘 第1步:在交叉编译环境(Ubuntu20.04_X86虚拟机)连接SD卡设备,使用fdisk 对SD卡进行分区,第一个分区起始地址要避开前64MB地址(First sector (2048-62333951,default 2048): 131072),空间0~64MB将用来存放fip-all.bin、kernel和设备树,64MB及之后空间是Linux...

Hello Friends, I am trying to run u-boot bootloader on i.mx6 sabre sd platform. I successfully compiled u-boot and created u-boot.imx and trying to
I have adapted the example for the Arria 10 SOCDK (Arria 10 SoC - Boot from SD Card) to the HAN-Pilot-Platform evaluation board from Terasic. I used the make_sdimage_p3.py script to generate the SD-Card image without linux binaries: Partition 3:...

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: ...
1.1、重新编译u-boot.bin,实现U-boot环境变量存储在MMC(eMMC/SD卡) 在交叉编译环境(Ubuntu20.04_X86虚拟机),进入Uboot源码目录,运行makemenuconfig配置环境参数保存在MMC设备,偏移地址为0x300000(这里0x00000-0x300000地址空间预留存放BIOS固件fip-all.bin,偏移地址必须大于fip-all.bin),然后重新make得到u-boot.bin...
Hi, I'm building system for RK3399-EVB (Shapphire V12) with scripts from rockchip-linux/build. The scripts basically just use the default config for RK3399. At rockhip-linux/u-boot HEAD e14b116: I'm able to boot U-Boot from SD card but t...

由于Ubuntu出现了一些问题,后面都是使用正点原子官方版本。 一、U-boot使用 1. U-boot源码 Linux 系统要启动需要通过 bootloader 程序引导,也就说芯片上电以后先运行一段 bootloader 程序。这段 bootloader 程序会先初始化 DDR 等外设,然后将
