前言
这里使用两种烧录方式,一种是PhoenixSuit官方烧录,参考MaixII M2dock 烧录系统,第二种是类似树莓派直接烧写镜像的方式。官方的讲解很完善了,这里主要讲第二种。由于win10烧录会导致GPT分区表错误,并且涉及到调整分区,这里将在linux系统下进行。
资源获取
## 烧录程序采用流行的Etcher
格式化软件
SDCardFormatter,这里用的win10的软件,根据个人爱好自行选择
镜像获取
系统烧录
- 格式化sd卡。使用SDCardFormatter一键格式化,或者手动格式化为MBR分区,FAT32格式。
-
挂载sd卡。插入设备后,执行
sudo fdisk -l
,出现如下设备
/dev/sdb1 8192 7744511 7736320 3.7G b W95 FAT32
即挂载成功。
- 使用dd命令烧录程序。先进入镜像所在文件夹,然后执行如下命令
gzip -dc v831.img.gz |sudo dd of=/dev/sdb bs=1M status=progress
烧录完毕后,执行执行sudo fdisk -l
,出现如下设备
/dev/sdb1 49152 49663 512 256K Microsoft basic data
/dev/sdb2 49664 61951 12288 6M Microsoft basic data
/dev/sdb3 61952 324095 262144 128M Microsoft basic data
/dev/sdb4 324096 487935 163840 80M Microsoft basic data
即烧录完毕。

扩展分区。如下:(省时间版:
sudo fdisk /dev/sdb p n 回车 回车 w
)
lithromantic@ubuntu:~/Desktop$ sudo fdisk /dev/sdb
Welcome to fdisk (util-linux 2.36.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
GPT PMBR size mismatch (499711 != 7744511) will be corrected by write.
The backup GPT table is not on the end of the device. This problem will be corrected by write.
Command (m for help): p

格式化分区。
sudo mkfs -t ext4 /dev/sdb5
-
挂载分区。挂载分区要在v831上执行,所以在此之前我们先测试下系统能否使用。
插入sd卡至V831,连接USB UART口和电脑usb口,打开串口终端,出现
BusyBox v1.27.2 () built-in shell (ash)
------run profile file-----

root@sipeed:/#
执行fdisk -l
,出现
Number Start (sector) End (sector) Size Name
1 49152 49663 256K env
2 49664 61951 6144K boot
3 61952 324095 128M rootfs
4 324096 487935 80.0M swap
5 489472 7744508 3542M

挂载分区。
临时挂载:mount /dev/mmcblk0p5 /home
这里是挂载到/home
路径下,可以自行修改。执行df
查看效果:
root@sipeed:/home# df
