哪吒 D1 通过 TF 卡运行 Arch Linux RISC-V rootfs

制作 RVBoards 的 Debian RISC-V TF 启动卡

  1. 详细资料参考这里 :「RVBoards-哪吒」D1 Debian系统镜像和安装方法
  2. 补充下这里面没提到的坑

说明您使用的SD卡存在GPT分区表残留,导致内核不知道如何找到rootfs。(似乎您忘记了在烧写前使用 wipefs 清理 GPT 备份分区表) 解决的办法如下:

  • 将出问题的SD卡插入PC,通过 gdisk 清除残余的分区表,过程如下:
# sdX 表示 TF/SD 卡磁盘号,此处以 sdf 为例
$ sudo gdisk  /dev/sdf
GPT fdisk (gdisk) version 1.0.5

Caution: invalid main GPT header, but valid backup; regenerating main header
from backup!

Warning: Invalid CRC on main header data; loaded backup partition table.
Warning! Main and backup partition tables differ! Use the 'c' and 'e' options
on the recovery & transformation menu to examine the two tables.

Warning! Main partition table CRC mismatch! Loaded backup partition table
instead of main partition table!

Warning! One or more CRCs don't match. You should repair the disk!
Main header: ERROR
Backup header: OK
Main partition table: ERROR
Backup partition table: OK

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: damaged

Found valid MBR and corrupt GPT. Which do you want to use? (Using the
GPT MAY permit recovery of GPT data.)
 1 - MBR
 2 - GPT
 3 - Create blank GPT

Your answer: 1

Command (? for help): p
Disk /dev/sdf: 62333952 sectors, 29.7 GiB
Model: Multi-Reader  -3
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 632BFA1B-F09D-42A8-82F4-5FAB32E41DC2
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 62333918
Partitions will be aligned on 2048-sector boundaries
Total free space is 37084093 sectors (17.7 GiB)

Number  Start (sector)    End (sector)  Size       Code  Name
   2           69632          319487   122.0 MiB   0700  Microsoft basic data
   3          319488         1320959   489.0 MiB   8300  Linux filesystem
   4         1320960        25319423   11.4 GiB    8300  Linux filesystem

Command (? for help): w

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y
OK; writing new GUID partition table (GPT) to /dev/sdf.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)
The operation has completed successfully.
  • 还可以通过 wipefs 擦除 TF 卡的分区信息
# sdX 表示 TF/SD 卡磁盘号
sudo wipefs -a /dev/sdX
sudo dd if=Fedora-riscv64-d1-developer-xfce-with-esp-Rawhide-latest-sda.raw of=/dev/sdX status=progress bs=4M
  1. 如果在 win 10 上通过 全志的 TF 卡制作启动盘工具请使用 PhoenixCardv4.2.7.7z 2021/07/14 08:56:40 更新的版本,否则会出现 启动卡无法格式化,无法制作成功等糟心的问题。

  2. 可选操作:扩展根文件系统分区尺寸:

    插入读卡器到linux系统下,执行以下操作来扩展根文件系统分区尺寸:(sdX的X表示你实际的读卡器盘符字母)

    sudo e2fsck -f /dev/sdX7
    sudo resize2fs -p /dev/sdX7
    

启动 Debian RISC-V TF卡

  1. 使用 USB2TTL 串口工具链接 D1 的 debug 口,插入 TF 到 D1 的 TF 卡座,
  2. 使用 minicom 连接串口
# 注意连接 如果出现键盘输入信息,串口接收不到的情况,请关闭 minicom 的硬件流控。
# 关闭 minicom 硬件流控
$ sudo minicom -s

# 按 F 切换硬件流控,选择为关闭,按回车间确认,放回到主界面保存设置。

# 连接 D1 串口
$ minicom -c on -b 115200 -D /dev/ttyUSB0
  1. 使用 Type-C 数据线连接 OTG 接口,minicom 会输出相应启动信息
  2. 不出意外的话会进入 Debian RISC-V 的系统
  3. Debian RISC-V 系统默认用户名:root 密码:rvboards

替换 Arch Linux RISC-V rootfs

  1. 国外的 sunxi-linux Nezha 介绍如何移植主线内核
  2. 肥猫的 Arch Linux RISC-V 项目
  3. 下载 arch risc-v rootfs 系统
# 将 archriscv-20210601.tar.zst 下载到 ~/ 下
$ wget -c https://archriscv.felixc.at/images/archriscv-20210601.tar.zst
  1. 将 D1 断电,拔出 TF 卡,通过读卡器挂载到电脑上
  2. 备份 Debian RISC-V 的 rootfs
# 此处以 sde5 为例,根据实际情况找到 rootfs 磁盘
$ mount /dev/sde5 /mnt
$ cd /mnt
# 备份当前 Debian RISC-V rootfs 
$ tar -zcvf . ~/debian-riscv-`date -s`.tar.xz
# 删除 Debian RISC-V rootfs
$ sudo rm -rf .
# 将 archriscv-20210601.tar.zst 解压到 /mnt 下
# Arch Linux 用户
$ sudo bsdtar -xvf ~/archriscv-20210601.tar.zst -C /mnt/
# 非 Arch Linux 用户,依赖 zstd 库,没有的此库的用户自行安装
sudo tar -I zstd -xvf ~/archriscv-20210601.tar.zst -C /mnt/
  1. 启动 Arch Linux RISC-V 虚拟机,Arch Linux RISC-V 的默认 root 密码为 sifive
$ sudo systemd-nspawn -D /mnt/ --machine archriscv -a -U
# Arch Linux RISC-V 的默认 root 密码为 sifive
  1. 配置 Arch Linux RISC-V 的静态 IP 地址
# 此处以默认网卡为 eth0 为例,实际通过  `ip addr` 获取网卡信息
# 查看网络状态
sudo systemctl status systemd-networkd 
# 通过 cat 配置静态 IP 文件
cat > /etc/systemd/network/10-static-eth0.network << EOF
[Match]
Name=eth0

[Network]
Address=192.168.1.199/24
Gateway=192.168.1.1
DNS=192.168.1.1 223.5.5.5 114.114.114.114
EOF
# 把服务加入开机自启
sudo systemctl reenable systemd-networkd
# 重启系统
sudo reboot
# 查看 IP
ip addr //  或者 ifconfig
# 如果静态 IP 重启后变成动态 IP,可以审查是否因为 `networkmanager` 引起,如果是请执行下面命令卸载
sudo pacman -Rsn `pacman -Qsq networkmanager` network-manager-applet
  1. 配置 /etc/fstab
# 使得根目录是 rw 的(这能避免一些 SEGV)
/dev/mmcblk0p5  /       ext4    rw      0       1
  1. 修改镜像源

    如果是是 SSL 连接错误,如下:

    pacman -Syyus
    .ac.cn/archriscv_archriscv.felixc.at_g' /etc/pacman.conf  cat /etc/pacman.conf            
    :: Synchronizing package databases...                                                                                                                                      
    error: failed retrieving file 'core.db' from archriscv.felixc.at : SSL certificate problem: certificate is not yet valid                                                   
    error: failed to update core (download library error)                                                                                                                      
    error: failed retrieving file 'extra.db' from archriscv.felixc.at : SSL certificate problem: certificate is not yet valid

    error: failed retrieving file 'community.db' from archriscv.felixc.at : SSL certificate problem: certificate is not yet valid

    error: failed to syn
# 将 https 替换成 http
sed -i 's_https_http_g' /etc/pacman.conf

如果是下载速度慢可以换其他镜像站:

sed -i 's_archriscv.felixc.at_mirrors.wsyu.edu.cn/archriscv_g' /etc/pacman.conf
  1. 退出 Arch Linux RISC-V 虚拟机
Ctrl + D
#
exit
  1. 卸载 /mnt 分区
sudo umount -R /mnt
  1. 安全弹出 TF 卡,插入 D1 TF 卡座,OTG 接口供电,不出意外是能进入 archlinux risc-v 的 rootfs

参考连接

Arch Linux 生命不息,折腾不止!
