简介

Firefly-RK3399 开发板分别带有两个MIPI,一个DVP摄像头接口,MIPI支持最高4K拍照,并支持 1080P 30fps以上视频录制。此外,开发板还支持 USB 摄像头。

本文以 OV13850/OV5640 摄像头为例,讲解在该开发板上的配置过程。

DTS配置

 isp0: isp@ff910000 {
	 …
	 status = "okay";
 }
 isp1: isp@ff920000 {
	 …
	 status = "okay";
 }

驱动说明

与摄像头相关的代码目录如下:

 Android:
 `- hardware/rockchip/camera/
    |- CameraHal             // 摄像头的 HAL 源码
    `- SiliconImage          // ISP 库,包括所有支持模组的驱动源码
       `- isi/drv/OV13850    // OV13850 模组的驱动源码
          `- calib/OV13850.xml // OV13850 模组的调校参数
 `- device/rockchip/rk3399/
    |- rk3399_firefly_box
    |  `- cam_board.xml     // 摄像头的参数设置


 Kernel:
 |- kernel/drivers/media/video/rk_camsys  // CamSys 驱动源码
 `- kernel/include/media/camsys_head.h

配置原理

设置摄像头相关的引脚和时钟,即可完成配置过程。

从以下摄像头接口原理图可知,需要配置的引脚有:AF_VDD28、DOVDD18、AVDD28、DVDD12、PWDN1、RST 和 MCLK。

  • MIPI 接口

Rk3399-camera-mipi-interface.jpg

  • DVP 接口

Rk3399-camera-cif-interface.jpg

  • AF_VDD28 可不做配置。

  • DOVDD18、AVDD28

DOVDD18、AVDD28 由 DVP_PWR 控制,DVP_PWR 对应 RK3399 的 GPIO1_C7:

Rk3399-camera-dvp.jpg

  • DVDD12

DVDD12 由 CIF_POWER 引脚控制,CIF_POWER 对应 RK3399 上的 GPIO1_C6 引脚:

Rk3399-camera-cif.jpg


  • PWDN1、RST

MIPI CIF:PWDN0(共用)、PWDN1、RST 对应 GPIO2_B4、GPIO2_D4、GPIO0_B0 引脚:

CIF_RST硬件上拉,无需额外配置

在开发板中,除了 DVDD12 (CIF_POWER) 要在 DTS中设置以外,其它引脚都是在 cam_board_rk3399.xml 中设置。

配置步骤

配置 Android

修改device/rockchip/rk3399/$(TARGET_PRODUCT)/cam_board.xml来注册摄像头:

编译内核需将 drivers\media\video\rk_camsys 驱动源码编进内核,其配置方法如下:

在内核源码目录下执行命令:

make menuconfig

然后将以下配置项打开:

Device Drivers  --->
 <*>Multimedia support  --->
        <*>camsys driver
         RockChip camera system driver  --->
                  <*> camsys driver for marvin isp
                  < > camsys driver for cif

最后执行:

make ARCH=arm64 rk3399-firefly.img

即可完成内核的编译。

调试方法

终端下可以直接修改/system/etc/cam_board.xml调试各参数并重启生效

FAQs

1.无法打开摄像头,首先确定sensor I2C是否通信。若不通则可检查mclk以及供电是否正常(Power/PowerDown/Reset/Mclk/I2cBus)分别排查
2.支持列表ː
13Mː OV13850/IMX214-0AQH5
