家电修理 2023-07-16 19:16www.caominkang.com电器维修

一、搭建编译环境 1、工具工具版本开发板正点原子 imx6ull 开发板gg-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihfubootuboot-imx-2016.03-2.1.0linuxlinux-imx-4.1.15 2、搭建 tftp 服务器

ubuntu20.04 搭建tftp服务器_lqonlylove的博客-CSDN博客_ubuntu配置tftp服务器

3、搭建 nfs 服务器

ubuntu20.04 搭建NFS服务器_lqonlylove的博客-CSDN博客

二、配置编译工具链 1、版本选择 2、解压

sudo tar -vxf g-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz

解压后名字太长，更改 g 文件夹名

onlylove@ubuntu:~/my/g$ ls
g-linaro-4.9.4  g-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz
onlylove@ubuntu:~/my/g$

3、配置

打开/etc/profile 以后，在面输入如下所示内容

export PATH=$PATH:/home/onlylove/my/g/g-linaro-4.9.4/bin

配置完后，重启主机。

4、验证

onlylove@ubuntu:~$ ls

三、uboot 1、版本选择

因使用正点原子开发板，选择正点原子提供uboot版本。

2、解压

tar -xvf uboot-imx-rel_imx_4.1.15_2.1.0_ga_alientek.tar.bz2

根据实际情况配置

setenv ipaddr 192.168.6.200
setenv gateayip 192.168.6.2
setenv serverip 192.168.6.129
saveenv

四、rootfs 1、版本选择 2、解压

tar -xvf rootfs.tar.bz2

五、Linux 1、版本选择 2、解压

4、uboot 加载启动 linux 1、uboot加载命令

tftp 80800000 zImage
tftp 83000000 imx6ull-alientek-emmc.dtb
bootz 80800000 - 83000000

2、uboot加载参数配置

setenv bootargs 'console=ttymxc0,115200 root=/dev/nfs nfsroot=192.168.6.129:/home/onlylove/my/nfs,proto=tcp,nfsvers=4 r ip=192.168.6.200:192.168.6.129:192.168.6.2:255.255.255.0::eth0:off'
