1 【平头哥Sipeed LicheeRV 86开发板试用】深度体验点亮LED 网络配置音视功能 Debian镜像等功能 tina Licheepi RV86系统体验系统镜像下载百度云下载的：链接：https://pan.baidu.com/s/1QJTaDw6kkTM4c_GAlmG0hg 提取码：wbef 烧录系统镜像上述下载有工具PhoenixCard烧录系统镜像(tina_d1-nezha_uart0.img)到miniSD卡打开烧录软件，选择启动卡(不知道哪里写的，我烧录量产是需要写NandFlahs才能启动，板子没有焊，所以启动不了，要迁启动卡)按顺序点击下图按键进行烧录对应镜像点亮LED 当我们成功进入系统后，就可以进行基础的点灯操作啦！（注：教程不适用于86-panel，因为对应引脚连接了外设，我们的Licheepi RV86panel用户可以拆下核心板来操作实验）核心板的螺丝固定焊盘旁有一颗LED，查看原理图：https://dl.sipeed.com/shareURL/L ... chee_RV/2_Schematic 可知该LED连接的是PC1，换算该IO的数字标号为：232+1=65，拆下核心板后没有串口和网络，只能用ADB Shell(ADB 真心不好用，不能tab 回退)连接开发板，用命令 cat /sys/kernel/debug/pinctrl/2000000.pinctrl/pinmux-pins 复制代码* 查看IO复用情况表： ... pin 64 (PC0): device 2008000.ledc function ledc group PC0 pin 65 (PC1): UNCLAIMED pin 66 (PC2): UNCLAIMED pin 67 (PC3): UNCLAIMED pin 68 (PC4): UNCLAIMED pin 69 (PC5): UNCLAIMED pin 70 (PC6): UNCLAIMED pin 71 (PC7): UNCLAIMED 复制代码导出GPIO65，并切换到GPIO65文件目录： echo 65 > /sys/class/gpio/export cd /sys/class/gpio/gpio65 复制代码Ｌinux下一切皆文件，　所以操作设备对应写文件即可，将该IO置为输出状态，即可操作其电平： echo out>direction echo 1 > value #LED点亮 echo 0 > value #LED熄灭复制代码其他小伙伴都成功在RISC-V 64 D1上点灯啦~ 而我的板子有问题，没能点亮．怎么我的板子那么多问题呢？用核心板　ADB可以使用adb进行文件传输，adb push/pull传文件但不方面, 下面体验外设，还是装回底板。外设功能体验 USB功能要用TPYE-C转USB-A，插上U盘默认内核支持外挂U盘的驱动，插上U盘后可以使用 fdisk -l 查看到新增的 /dev/sda如果U盘没有被格式化，可以使用mkfs.vfat指令来格式化U盘，再使用mount指令挂载默认Tina固件里的 /dev/mmcblk0p8 分区即可使用上述方式格式化后挂载，来提升可用空间下载是我们U盘内容了 root@MaixLinux:/mnt/exUDISK# cd /mnt/exUDISK/ root@MaixLinux:/mnt/exUDISK# ls APK_TV DreamItPossible.mp4 ISO extra Documents GHO System Volume Information sun.jpg 复制代码复制到系统内（/tmp空间，到/root会满的）： root@MaixLinux:/mnt/exUDISK# cp DreamItPossible.mp4 sun.jpg /tmp root@MaixLinux:/mnt/exUDISK# cd /tmp root@MaixLinux:/tmp# ls 3D_earth.gif eleReport1.gif lock smart.gif wpa_ctrl_180-33 3car.gif empty log ssh-iCtbeOicfd wpa_ctrl_180-34 China_99B.mp4 extroot lushanpubu640.gif state yong.gif DreamItPossible.mp4 girl.gif resolv.conf sun.jpg Fourier_series_and_transform.gif girl1.gif resolv.conf.auto sun9.gif booting_state lib run sysinfo eleReport.gif localtime shm tmp 复制代码看到已经到/tmp目录下了，等会体验多媒体功能会用到的，这样传文件，要拔插U盘也不方面，最方面是用网络传文件。下面我们来搞定网络吧配置有线网络 LicheeRV-86 Panel 支持百兆网络，使用套餐附送的网线尾线接上网线后，执行以下指令来连接有线网络 ifconfig eth0 up udhcpc -ieth0 复制代码配置无线网络 LicheeRV86 底板默认使用XR829 wifi模块，可以使用以下指令进行联网操作：先配置热点信息： vim /etc/wifi/wpa_supplicant.conf network={ ssid="Wifi ssid name" psk="password ***" } 配置完成后重启 ifconfig wlan0 up; udhcpc -iwlan0 复制代码* 即可连上对应的wifi。重启看到有线和无线都连接成功，其实有一个即可 root@MaixLinux:/tmp# ifconfig eth0 Link encap:Ethernet HWaddr 9E:75:60:17:DA:4F inet addr:192.168.0.73 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::9c75:60ff:fe17:da4f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:264 errors:0 dropped:0 overruns:0 frame:0 TX packets:55 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:24023 (23.4 KiB) TX bytes:4592 (4.4 KiB) Interrupt:62 wlan0 Link encap:Ethernet HWaddr 08:BE:E0:98:24:70 inet addr:192.168.0.70 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::abe:e0ff:fe98:2470/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:17857 errors:0 dropped:0 overruns:0 frame:0 TX packets:11370 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22775139 (21.7 MiB) TX bytes:13022254 (12.4 MiB) 复制代码连上网络后，就可以使用ssh远程登录板卡，或者使用scp来进行文件传输啦~ 推荐此工具MobaXterm全带有串口终端 ssh scp sftp.......... 使用ssh登录，要用户名密码为 root，tina 音频功能体验传文件到开发板注传到/tmp目录，　/root目录　快满了如传/root目录，可以会出错误 df命令查看便知： df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 99884 82196 10520 89% / devtmpfs 247644 8 247636 0% /dev tmpfs 251840 59576 192264 24% /tmp /dev/mmcblk0p1 8151 677 7474 8% /mnt/SDCARD 复制代码查看相关用法aplay aplay -h Usage: aplay [OPTION]...
