100ASK百问网 D1s/T113-s3开发板 适配ov5640
-
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.zip1.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。

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
-
@null037 按照配置，MQ-R 板子已出图
-
@null037 本身就是tina系统的话，应该怎么适配呢
-
@null037 Tina测试镜像：tina_t113-100ask_uart3.img
-
V851S是不是也是一样的方法呢
-
@null037
刷以上固件，ov5640接对应条线帽，加载驱动报错如下：
