100ASK百问网 D1s/T113-s3开发板适配ov5640

NULL037 LV 6

本实验采用百问网的100ASK_T113-PRO Base V1.1 ，链接：韦东山全志T113开发板
D1s也可以参考进行修改并适配。
本实验所需的文件（含tina根文件系统、SD镜像、设备树、内核配置文件）供大家对比参考：source.zip

1.硬件配置

查看百问网提供的T113开发板原理图100ASK_T113-Pro_Base-SCH.pdf
通过查看到第3页的摄像头原理图

①将PE引脚使用跳线帽连接至CSI引脚。

②根据所使用的摄像头，利用跳线帽，使AVDD、DVDD、DIOVDD选择不同的电压

我所使用的是ov5640，使用2.8V的AVDD、1.5V的DVDD、2.8V的DIOVDD

③根据摄像头的引脚信息，上接至T113开发板的DVP接口

2.修改设备树

注意：T113中的网口和CSI接口复用，注意设备树中网口的PE的复用功能需要修改为CSI的PE的复用功能。

		};

3.修改内核配置

在buildroot目录下，输入

make linux-menuconfig

进入内核配置界面中的下面目录：
Location:
│ -> Device Drivers
│ -> Multimedia support

对于Media USB Adapters：

对于V4L platform devices：

对于SUNXI platform devices：

对于Memory-to-memory multimedia devices：

修改完成后，保存并退出。

4.重新编译和烧写

在buildroot目录下执行

make linux-rebuild

执行完成后，再打包生成SD卡镜像，输入

make -j4

5.使用tina的根文件系统启动

将烧录到sd卡的t113系统挂载到ubuntu中使用 df -h 查看分区

进入分区

cd /media/book/dd79b15c-ce3f-4d2d-8a75-437303b2df61/

拷贝lib中的驱动到桌面备用

sudo cp -rf lib/modules/5.4.61 ~/Desktop

删除全部文件

sudo rm -rf *

将source文件夹中的tina_rootfs目录下的rootfs.img拷贝到Ubuntu中，解压tina系统

unsquashfs  rootfs.img

拷贝tina系统中的文件到当前目录

sudo cp /home/book/squashfs-root/* ./ -rfd

进入lib/modules目录下删除5.4.61文件夹

cd lib/modules/

sudo rm -rf 5.4.61

将5.4.61文件夹拷贝回去

sudo cp ~/Desktop/5.4.61/ ./ -rf

从虚拟机中弹出SD卡。

6.使用camerademo测试

将SD卡插入T113开发板，上电启动。启动界面如下：

进入sunxi-vin目录：

cd /lib/modules/5.4.61/kernel/drivers/media/platform/sunxi-vin/

装载vin_io.ko驱动

进入sensor目录：

cdcd modules/sensor/

装载ov5640.ko驱动：

insmod ov5640.ko

回到sunxi-vin目录：

装载vin_v4l2.ko驱动：

insmod vin_v4l2.ko

注意：上述大部分打印信息为我调试时加的打印，与自带驱动无关，全志自带的驱动程序是正常。

插入U盘或无系统的TF卡将获取到的图片提取出来查看。

挂载U盘。

mount /dev/sda1 /mnt/

使用camerademo拍摄照片，存放到U盘内

camerademo NV21 640 480 30 bmp  /mnt 5

卸载U盘分区

umount /mnt/

拔下u盘，插入电脑中，即可查看到刚刚在T113开发板上使用ov5640拍摄的5张照片

@null037 在 100ASK百问网 D1s/T113-s3开发板适配ov5640 中说：

，插入电脑中，即可查看到刚刚在T113开发板上使用ov5640拍摄的5张照片

强烈建议光速适配下MQ-R

hameyou LV 2

@null037 按照配置，MQ-R 板子已出图

z15612417860 LV 3

@null037 本身就是tina系统的话，应该怎么适配呢
