MQ-Pro D1-H ov5640适配

[kw___]

通过查看原理图发现并无其他外设占用DVP接口，但是在board.dts的wifi占用了PE3接口，后又查看原理图，发现wifi原理图引脚和设备树引脚并没对上。直接下载的源码编译生成的镜像并不能使用wif，并且没有挂在overlay分区，系统并不是可写的。

简单进行wifi引脚修改，修改之后并不能使用wifi，这里只是释放PE3引脚，wifi驱动也不太会开启，就没有去配置。

修改前 vim device/config/chips/d1/configs/mq_pro/board.dts +527

修改后

ov5640设备树默认已经配置好，就不用再设置了

执行

source build/envsetup.sh

lunch 1

make kernel_menuconfig

在 > Device Drivers > Multimedia support 开启：

进入 > Device Drivers > Multimedia support > SUNXI platform devices

进入 > Device Drivers > Multimedia support > Memory-to-memory multimedia devices

在编译前，进入如下目录删除里面的 ko 文件

lichee/linux-5.4/drivers/media/common/videobuf2/
lichee/linux-5.4/drivers/media/platform/sunxi-vin/
lichee/linux-5.4/drivers/media/platform/sunxi-vin/modules/sensor

以下目录没有就不用了

out/d1-mq_pro/compile_dir/target/linux-d1-mq_pro/linux-5.4.61/drivers/media/common/videobuf2/
out/d1-mq_pro/compile_dir/target/linux-d1-mq_pro/linux-5.4.61/drivers/media/platform/sunxi-vin/
out/d1-mq_pro/compile_dir/target/linux-d1-mq_pro/linux-5.4.61/drivers/media/platform/sunxi-vin/modules/sensor

make menuconfig

执行 make -j12 && mboot && pack

中间需要配置，直接回车默认就行

复制 lichee/linux-5.4/drivers/media/common/videobuf2/ 中的 videobuf2-dma-contig.ko videobuf2-memops.ko videobuf2-vmalloc.ko

复制 lichee/linux-5.4/drivers/media/platform/sunxi-vin/ 中的 vin_io.ko vin_v4l2.ko

复制 lichee/linux-5.4/drivers/media/platform/sunxi-vin/modules/sensor 中的 ov5640.ko

到win下的目录，建立ko一块存起来

拷贝out/d1-mq_pro/compile_dir/target/camerademo/中的 camerademo 到 win

烧录编译好的镜像，这里把文件都上传至 tmp 目录

adb push .\ko\ /tmp

adb push .\camerademo /tmp

然后进入 shell

insmod ko/videobuf2-memops.ko

insmod ko/videobuf2-dma-contig.ko

insmod ko/videobuf2-vmalloc.ko

insmod ko/vin_io.ko

insmod ko/ov5640.ko

insmod ko/vin_v4l2.ko

可以看到生成video0节点，执行

chmod +x /tmp/camerademo

. /tmp/camerademo

抓到图片

通过adb pull /tmp .

遇到的问题，暂时无法解决

1 自己编译的镜像没有挂载 overlay

默认的如下配置并不起作用，target/allwinner/d1-mq_pro/base-files/etc/config/fstab

添加 rootfs_data 分区后，再修改如下，仍是只读文件系统，并且 /mnt/UDISK /overlay分区没有挂载

编译出来的镜像没有这个文件，如下为官网下载的

自己编译的

2 参考如下步骤，ko文件并没有编译出来，也没有拷贝到/lib....目录下

mq-r t113 ov5640适配 | 全志在线开发者论坛 (aw-ol.com)

3使用其他镜像加载驱动

芒果派 ( Mango Pi ), 小巧优雅的单板电脑 | mqpro

官网下载的镜像，wifi功能正常且系统可写，默认设备树应该已经配置好了，所以直接拷贝ko到该文件系统中，成功加载了，但是发现PE引脚默认用作了eth外设，并且i2c通信会出了问题，并且i2cdetect检测不到设备
