【RP-RV1126】配置一套简单的板级配置

官方配置

buildroot官方配置完整编译需要30分钟。我想搞一个简单的配置，可以快速编译，快速测试一些简单的功能。

命令	对应的文件	描述
./build.sh lunch	pro-liefyuan-rv1126.mk	选择全局配置文件
source envset.sh	rockchip_rv1126_rv1109_liefyuan_defconfig	选择Buildroot配置文件

新建一套新配置

新建板级pro-liefyuan-rv1126.mk配置文件

定义一个自己的pro-liefyuan-rv1126.mk文件：
基于原来的文件：./device/rockchip/rv1126_rv1109/pro-rv1126.mk
改为：./device/rockchip/rv1126_rv1109/pro-liefyuan-rv1126.mk

拷贝目录sdk/device/rockchip/rv1126_rv1109/下的pro-rv1126.mk改成自己的名字：pro-liefyuan-rv1126.mk

目前的打算，只修改Buildroot文件系统的配置，Uboot和Kernel的配置不变。

# Buildroot config
export RK_CFG_BUILDROOT=rockchip_rv1126_rv1109_facial_gate

改为：

# Buildroot config
export RK_CFG_BUILDROOT=rockchip_rv1126_rv1109_liefyuan

pro-liefyuan-rv1126.mk 的全部内容：

#!/bin/bash# Target arch
export RK_ARCH=arm
# Uboot defconfig
export RK_UBOOT_DEFCONFIG=rv1126
# Uboot image format type: fit(flattened image tree)

export RK_PACKAGE_FILE=rv1126_rv1109-package-file

新建一个Buildroot的defconfigs文件

定义一个自己的Buildroot的configs文件：
基于原来的文件：./buildroot/configs/rockchip_rv1126_rv1109_facial_gate_defconfig
改为：./buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig

$ cp ./buildroot/configs/rockchip_rv1126_rv1109_facial_gate_defconfig ./buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig

原来的Buildroot配置太复杂了我精简到如下：

buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig 文件的全部内容：

#include "base.config"
#include "base_extra.config"
#include "debug.config"
#include "audio.config"
#include "wifi.config"
#include "network.config"
#include "rv1126_rv1109_arm.config"
#include "updateEngine.config"
BR2_PACKAGE_RKWIFIBT_AP6256=y
BR2_PACKAGE_RKWIFIBT_BTUART="ttyS0"
BR2_PACKAGE_DRM_DISPLAY_OUTPUT=y
BR2_PACKAGE_LIBERATION=y
BR2_PACKAGE_SOURCE_HAN_SANS_CN=y
BR2_PACKAGE_QT5BASE_WIDGETS=y
BR2_PACKAGE_QT5BASE_FONTCONFIG=y
BR2_PACKAGE_QT5BASE_GIF=y
BR2_PACKAGE_QT5BASE_JPEG=y
BR2_PACKAGE_QT5BASE_PNG=y
BR2_PACKAGE_QT5BASE_USE_RGA=y
BR2_PACKAGE_QT5BASE_LINUXFB_ARGB32=y
BR2_PACKAGE_QT5MULTIMEDIA=y
BR2_PACKAGE_QT5QUICKCONTROLS=y
BR2_PACKAGE_QT5SERIALPORT=y
BR2_PACKAGE_BLUEZ_TOOLS=y
BR2_PACKAGE_BLUEZ5_UTILS=y
BR2_PACKAGE_BLUEZ5_UTILS_OBEX=y
BR2_PACKAGE_BLUEZ5_UTILS_CLIENT=y
BR2_PACKAGE_BLUEZ5_UTILS_GATTTOOL=y
BR2_PACKAGE_DHCP=y

这里其实就设置了WiFi蓝牙相关和Qt相关的配置，整个编译下来不到8分钟。

吐槽：RP-RV1126 的SDK奇怪的地方

make ARCH=arm xxx_defconfig 生成的.config文件位置不一样

• 一般来说（主线Buildroot），我在Buildroot根目录下运行命令：make ARCH=arm xxxx_defconfig，会在当前目录下产生一个.config文件,但是Rockchip的不一样，运行了上述命令后，它是会在这里产生该文件：./output/xxxx/.config

savedefconfig命令直接替换原配置文件

liefyuan@ubuntu:~/rv1126/rp_rv1126_sdk/buildroot$ make ARCH=arm savedefconfigGEN     /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/output/rockchip_rv1126_rv1109_liefyuan/Makefile
grep "#include" /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig > /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig.split || true
cat /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig >> /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig.split

rm /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig.split

/home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/build/defconfig_hook.py -s /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig.split /home/liefyuan/rv1126/rp_rv1126_sdk/buildroot/configs/rockchip_rv1126_rv1109_liefyuan_defconfig 这句话把我震惊了，我运行命令make ARCH=arm savedefconfig之后它直接保存到原文件了。。。。

坑爹的地方

• 清除buildroot的编译内容，需要进入sdk/buildroot/目录进行make clean才可以清除。
• ./build.sh cleanall并不能清除所有生成文件
• 重新编译的顺序：
  • 全部清除：./build.sh cleanall
  • 删除固件等：cd ./rockdev 然后 rm ./*
  • 重新编译：./build.sh all
  • 构建一次完整固件：./build.sh updateimg

Buildroot上增加WiFi和BT

增加BT需要确定连接的串口号

根据以上信息，确认BT串口连接的是UART0，也就是ttyS0。

因此Buildroot里面配置相应的串口号。

WiFi/BT模块的模块和固件位置

开发板上的位置

/system/lib/modules/bcmdhd.ko #驱动ko（如果是ko编译的话）
/system/etc/firmware/fw_bcm43455c0_ag.bin #驱动firmware文件存放位置
/system/etc/firmware/nvram_ap6255.txt #驱动nvram文件存放位置
/system/etc/firmware/BCM4345C0.hcd #蓝牙firmware文件（如果有蓝牙功能）

BT使用过程：

killall brcm_patchram_plus1echo 0 > /sys/class/rfkill/rfkill0/state # 下电
echo 1 > /sys/class/rfkill/rfkill0/state # 上电brcm_patchram_plus1 --bd_addr_rand --enable_hci --no2byt
es --use_baudrate_for_download --tosleep 200000 --baudrate 1500000 --patchram /s
ystem/etc/firmware/bcm43438a1.hcd /dev/ttyS0 &hciconfig -a
hciconfig hci0 uphcitool lescan
hcitool scan

进入BT交互模式

cd /usr/libexec/bluetooth/
./bluetoothd -n -d &bluetoothctl

在bluetoothctl中，我们可以进行手动配对操作。配对时，我们需要提供设备的MAC地址，并且将设备设置为可被发现模式。

$ bluetoothctl
[bluetooth]# power on
[bluetooth]# discoverable on
[bluetooth]# scan on
[bluetooth]# devices
Device 20:13:03:22:66:19 Bose SoundSport Wireless
[bluetooth]# pair 20:13:03:22:66:19
[bluetooth]# trust 20:13:03:22:66:19
[bluetooth]# connect 20:13:03:22:66:19
[bluetooth]# exit
