BPI-R4 引导程序和设备选择跳线设置：

所有跳线为“1”，BPI-R4将从SD卡启动
SW3-A 为“0”，SW3-B 为“1”，BPI-R4 将从 SPI NAND 启动
SW3-A 为“1”，SW3-B 为“0”，BPI-R4 将从 eMMC 启动
如果控制台显示“systemhalt!”，则表示启动存储不包含任何操作系统F0：102B 0000传真：5100 0000传真：5100 0000 [0200]F9：1041 0000F3：1001 0000 [0200]F3：1001 0000F6：102C 0000F5：1026 000000：1005 0000传真：5100 0000传真：5100 0000 [0200]F9：1041 0000F3：1001 0000 [0200]F3：1001 0000F6：102C 000001：102A 000102：1005 0000BP: 0200 00C0 [0001]欧共体：0000 0000 [0000]MK: 0000 0000 [0000]T0：0000 00D7 [0101]系统死机！

如何为SD、EMMC Nand烧写镜像

发布图片：https ://wiki.banana-pi.org/Banana_Pi_BPI-R4#Release_image

注意：启动设备选择：https://wiki.banana-pi.org/Getting_Started_with_BPI-R4#Prepare_to_develop

如何将图像刻录到SD卡

A.注意：在linux电脑上将镜像烧录到SD卡- 1.您可以从我们的论坛下载最新的图片- 2.在 Ubuntu 上安装 bpi-tools。如果您无法访问此 URL 或出现任何其他问题，请转至 bpi-tools 存储库并手动安装此工具。- apt-get 安装光伏- 卷曲-sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash- 3.下载镜像后，将TF卡插入Ubuntu- 执行“bpi-copy xxx.img /dev/sdx”将镜像安装到TF卡上- 4.完成步骤3后，您可以将TF卡插入R4，然后按电源按钮对R4进行设置
B. 注：在 Windows 计算机上将映像刻录到 SD 卡- Balena Etcher 是 Balena 的一款开源 GUI 闪存工具，可将操作系统映像闪存到 SD 卡或 USB 驱动器。- 单击“Flash from file”以选择图像。- 单击“选择目标”以选择 USB 设备。- 点击“闪光！”开始燃烧。
C. 将启动跳线更改为从 SD 启动，启用 SD 卡设备。- 注意：启动设备选择：https://wiki.banana-pi.org/Getting_Started_with_BPI-R4#Prepare_to_develop- 注意：请对SD卡进行低级格式化，并清除SD卡中的所有数据。这很重要。

如何将镜像烧录到板载Nand上

当您想要更新 Nand 设备时，首先将启动开关更改为从 SD 设备启动，并插入一张带有 SD 启动映像的 SD，然后启动后，您需要将一张 nand 映像闪存到 nand 设备中。最后将 bootstrap 更改为从 Nand 设备启动。

在将镜像烧录到Nand之前，请准备一个U盘。我们以OpenWrt镜像（mtk-bpi-r4-NAND-20231030.img）为例，步骤如下：

将 Nand 启动 OpenWrt 映像（mtk-bpi-r4-NAND-20231030.img）复制到 U 盘。
更改启动开关跳线，板子从SD设备启动，然后给板子上电。
将U盘插入开发板，并将U盘挂载到/mnt或其他目录，如下：（如果自动挂载则可以跳过挂载）- 挂载-t vfat /dev/sda1 /mnt- 将目录更改为安装点，这里是： cd /mnt
执行以下命令擦除整个 Nand flash 并将映像复制到 nand 设备：- mtd 擦除 /dev/mtd0- dd if=mtk-bpi-r4-NAND-20231030.img of=/dev/mtdblock0
关闭BPI-R4板的电源，拔掉U盘驱动，将bootstrap更改为从Nand设备启动。- 注意：启用Nand设备，引导程序来自Nand。- 注意：启动设备选择：https://wiki.banana-pi.org/Getting_Started_with_BPI-R4#Prepare_to_develop

如何烧录镜像到板载eMMC

由于SD卡和EMMC设备共用一个SOC的控制器，因此需要切换到NAND启动，然后将EMMC镜像烧录到EMMC中。最后，您将启动更改为从 EMMC 启动。

在将镜像烧录到eMMC之前，请准备一个U盘。我们以OpenWrt镜像（bl2_emmc-r4.img、mtk-bpi-r4-EMMC-20231030.img）为例，步骤如下：

将 EMMC 启动 OpenWrt 镜像（bl2_emmc-r4.img、mtk-bpi-r4-EMMC-20231030.img）复制到 U 盘，如果镜像被压缩，请在复制到 U 盘之前解压。
将开关跳线改为Nand，从Nand启动主板。注意：启用Nand设备，引导程序来自Nand
将U盘插入开发板，并将U盘挂载到/mnt或其他目录，如下：（如果自动挂载则可以跳过挂载）- 挂载-t vfat /dev/sda1 /mnt- 将目录更改为安装点，这里是： cd /mnt
执行：- 回声 0 > /sys/block/mmcblk0boot0/force_ro- dd if=bl2_emmc-r4.img of=/dev/mmcblk0boot0- dd if=mtk-bpi-r4-EMMC-20231030.img of=/dev/mmcblk0- mmc 引导部分启用 1 1 /dev/mmcblk0
关闭R4板电源，删除u盘驱动，将bootstrap更改为从emmc设备启动。- 注意：启用 EMMC 设备，引导程序来自 EMMC。- 注意：启动设备选择：https://wiki.banana-pi.org/Getting_Started_with_BPI-R4#Prepare_to_develop

网络配置

网络配置参考：http://www.fw-web.de/dokuwiki/doku.php ?id=en:bpi-r2:network:start
网络接口：eth2、lan0用于WAN； eth1、lan0、lan1、lan2、lan3 用于 LAN，ra0/ra1 用于 2.4G 无线，rai0 用于 5G wifi6 无线，rax0 用于 6G wifi7 无线。

配件

10G SFP模块

BPI-R4的SFP Serdes速度固定为10Gbps，因此只能使用支持此功能的SFP！

通常10G SFP+模块的PIN6为GND。插入模块后，SFP_MOD_DEF0将被拉低，从而打开SFP电源。

因此，如果模块的该PIN不为GND，则不会提供3.3V_SFP电源！

10G SFP+ 铜缆模块

该模块长时间使用时温度很高，在不加散热器或散热风扇的情况下可达90℃。注意防止烫伤！

复制

注意：该模块插入后请勿拔出，否则会导致BPI-R4重启。其他模块不存在此现象。

4G 5G模组

BPI-R4支持4G LTE EC25。移远RM500U-CN和RM520N-GL 5G模块。

如果您想在 BPI-R4 上使用 5G：

将 5G 适配器插入 USB3.0。
将RG200U-CN连接至mini PCIe，通过USB2.0（限速）连接SoC。
制作一块RG200U-CN LGA转接板并将其插入M.2 KEY M。

注：4G/5G 的可用性取决于当地运营商频段。

BPI-R4 还支持 ASMedia 的 ASM2142。但该模块需要额外的5V电源。

该模块可以用在M.2 KEYB插槽上（但是模块尺寸为2260，没有地方可以修复）

Wi-Fi7网卡

您可以将BPI-R4-NIC插入BPI-R4-Main底部的CN12和CN14，然后用两颗M2螺钉固定。

BPI-R4-NIC 模块需要 12V 电源，因此上电前必须先打开 BPI-R4-Main 上的电源（SW4 拨至“ON”位置，上电时 12V LED 会亮起）在）

12V 电源将通过 miniPCI 插座的 PIN6/8/48 提供给 BPI-R4-NIC。插接其他模块时，如果无法确认模块是否能承受12V，请务必关闭SW4。
