Allwinner V3s SD 运行 Alpine Linux 发行版总结(适用于 H3 等其他 ARM 板)

Alpine Linux is a security-oriented, lightweight Linux distribution based on musl libc and busybox.
https://www.alpinelinux.org/
特点:
- 根文件系统采用 tmpfs,掉电会丢失当前运行参数,重新恢复到原系统状态
- 采用 lbu commit 可以保存配置等信息
- 采用 apk 包管理系统

1. SD 卡格式化为 FAT 格式,可选添加其他分区

2. 编译和烧写 u-boot 到 SD 卡

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/<sdx> bs=1024 seek=8

3. 下载解压 Generic ARM 压缩文件至 SD boot 分区 FAT 目录
  http://dl-cdn.alpinelinux.org/alpine/v3.12/releases/armv7/alpine-uboot-3.12.0-armv7.tar.gz

4. 上电即可运行,系统配置和管理参考
wiki 链接:https://wiki.alpinelinux.org/wiki/Main_Page
apk 镜像源:https://mirrors.alpinelinux.org/

5. 关于外设驱动
- alpine linux 内核编译配置信息在 boot 目录 config-lts
- alpine linux usb kernel 驱动配置为 "host" 模式,v3s 设备树默认为 "otg", 修改设备树为 usb dr_mode 为 "host", 参考 H3 添加 ohci0 ehci0, 重新编译设备树即可识别 USB 外设,已实测可以 U盘,USB WiFi 网卡,4G 模块。。
- V3s 驱动和 H3 类似,例如以太网,LCD 参考 H3 设备树配置即可

Re: Allwinner V3s SD 运行 Alpine Linux 发行版总结(适用于 H3 等其他 ARM 板)

看了WIKI说安装使用的最小内存是256M和128M, 那么64M的V3S是不够的。 楼主试了吗?

有兴趣可以看下面运行日志,mount sd卡其他分区到 /usr 目录,可以安装 gcc,gdb, openssl-server 等, 实测可以用 Windows Visual Studio 通过 ssh 开发 V3s 的 linux 程序。
