基于V851S的USB-UVC摄像头板发布在 V853系列-AI视觉
大家好，
我是一名嵌入式系统的学生（来自法国），我正在围绕 V851S 制作这个小板。 它应该用于连接树莓派相机或 esp32-cam 相机，并使用 usb-uvc 将它们用作 USB 网络摄像头。
该项目仍处于早期阶段，我是这个论坛的新手，所以我想我只是将其作为介绍发布。以下是该板的一些图片：

V851s buildroot openwrt 编译GCC失败发布在 编译和烧写问题专区
大家好，
我已经使用 yukilizard 项目的 BSP 以及 tina-V853 存储库成功为 V851S 构建了映像。 但现在我想为 V851S 构建 GCC。 当我在 Developpement->GCC 中启用该选项（它自己启用其他选项）并且我“make”时，它编译得很好，直到到达 GCC，此时我遇到了此错误：
make menuconfig options
error有谁知道我如何/是否可以解决这个问题？

V851S I2C/TWI 损坏（xfer 错误)发布在 V853系列-AI视觉

我的 V851S (tina-linux) 上的 i2c/twi 总线似乎有问题，每次我尝试使用 i2cdump 或 i2cDetect 等 shell i2C 实用程序时，我都会收到以下错误 （i2cget 和 i2cwrite 也会发生这种情况）：root@TinaLinux:/sys/devices/platform/soc/pio/gpiochip0/gpio/gpio8# i2cdetect 1 [ 786.358195] i2c i2c-1: ioctl, cmd=0x705, arg=0xbea72c6c i2cdetect: WARNING!

我知道至少已经有一篇关于此问题的帖子，但这只是一条警告消息，在我的情况下，它无法正常工作，因为我在 I2C 1 的地址 0x36 上有一个未检测到的设备。我怎样才能摆脱这些错误？
我的 twi DTS 配置如下：

回复: V851S kernel_menuconfig 设置未应用发布在 编译和烧写问题专区
事实证明 .ko 文件确实是由“make”命令构建的，但它们只是没有被发送到图像：
为了能够将它们包含在图像中，我必须编辑 openwrt/target/v851S/<board_name> 中的文件：
添加我需要的各种 ov 驱动程序并注释掉我不需要的 gc2053 驱动程序
这仍然有点奇怪，这不是自动配置的，需要您手动编辑这些 makefile...感觉很笨重

V851S tina linux ov5647 驱动程序没有 dmesg发布在 V853系列-AI视觉
大家好，
在修复了我的 i2c 并使用 i2cDetect 和手动 GPIO 选择手动检测到我的相机后，我正在尝试为相机制作一个驱动程序。
我将它基于已经存在的 OV5468 mipi 驱动程序。 我更改了所有必需的标识符和寄存器/值，以使其符合 ov5647 的要求，我编辑了必要的 makefile 来构建它，并为新传感器配置了板的 DTS。
我的问题是这样的：
当我使用 insmod 加载 ov5647_mipi.ko 内核模块时，没有任何反应。 即使我将日志级别设置为 8，并且我在驱动程序中放置了各种 printk() 调用，但 dmesg 中根本没有出现任何消息，但这些调用实际上都没有显示在日志中。 你们知道我可能错过了什么吗？ 也许是某个特定的配置使日志静音？ DTS 错误？root@TinaLinux:/lib/modules/4.9.191# ls ov5640.ko soc_camera.ko videobuf-core.ko ov5647_mipi.ko soc_camera_platform.ko videobuf2-dma-contig.ko ov5648_mipi.ko soc_mediabus.ko vin_io.ko ov5658.ko uvcvideo.ko vin_v4l2.ko root@TinaLinux:/lib/modules/4.9.191# lsmod Module Size Used by vin_v4l2 176157 0 vin_io 19952 1 vin_v4l2 videobuf2_dma_contig 8632 1 vin_v4l2 root@TinaLinux:/lib/modules/4.9.191# insmod ov5647_mipi.ko root@TinaLinux:/lib/modules/4.9.191# lsmod Module Size Used by ov5647_mipi 6469 0 vin_v4l2 176157 0 vin_io 19952 2 ov5647_mipi,vin_v4l2 videobuf2_dma_contig 8632 1 vin_v4l2 root@TinaLinux:/lib/modules/4.9.191# dmesg | tail root@TinaLinux:/lib/modules/4.9.191#我的DTS：

回复: V851S tina linux ov5647 驱动程序没有 dmesg发布在 V853系列-AI视觉
我让它工作了，似乎驱动程序需要在启动时正确加载，否则 DTS 将传感器设置为“禁用”。
另一方面，我基于 ov5647 的 ov5648 官方 allwinner 驱动程序的寄存器似乎完全错误！ 它是一个 mipi 驱动程序，它修改相机中与并行 csi 相关的寄存器，完全是废话......我正在从头开始重写它。

V851S kernel_menuconfig 设置未应用发布在 编译和烧写问题专区
大家好，
当我在 kernel_menuconfig 中将 OV5640 和 OV5658 驱动程序设置为编译为模块 (M) 时（并且禁用 gc_2053）：
我编辑 DTS 以反映更改：
并编译/运行，似乎没有考虑到更改。 menuconfig 中的其他更改确实适用于图像，但 kernel_menuconfig 中完成的某些更改则不然。 看这里，gc_2053 驱动程序仍然处于活动状态，而 OV 驱动程序却不见踪影：
知道为什么会出现这种情况吗?

回复: V851S I2C/TWI 损坏（xfer 错误)发布在 V853系列-AI视觉
我让它工作了！
我必须编辑 DTS 将驱动强度增加到 1，并将 1.8V 总线电压从 1.7V 提高到 2V 才能注册，现在我的相机出现了!
默认的 0 驱动强度永远不会起作用。 编辑 DTS 是关键。

回复: V851S tina linux ov5647 驱动程序没有 dmesg发布在 V853系列-AI视觉
我已经购买了树莓派相机模块 V2 (IMX219)，我尝试使用提供的驱动程序模块，很明显它无法像现在一样工作。 我必须将通道设置更改为 2 通道和相应的寄存器，因为驱动程序默认配置为 4 通道 mipi csi 操作。
经过几次测试后，我遇到了同样的问题，camerademo 超时并且不保存任何帧。 正如您在日志中看到的那样，I2C 配置已完美发送，它与我发送的配置匹配，寄存器有意义，数据格式应为 RGB8 位。

这些“VIN 格式不支持”错误也很奇怪，因为我似乎使用了正确的格式。
我附上了我的IMX219.C驱动程序的修改版本，如果有人想看一下，我现在唯一尝试支持的设置是720P。
imx219.c
ov5647_mipi.c我还附上了主板的完整启动日志，有很多启动错误，但我怀疑它们实际上与当前问题有关，因为所有必需的模块都已加载。
也许有人能够发现我错过的明显的东西......

回复: V851S tina linux ov5647 驱动程序没有 dmesg发布在 V853系列-AI视觉
@awwwwa 我已经研究过 @YuzukiTsuru 制作的这个特定驱动程序，它存在一些问题：
- 未正确配置与 OV5647 的接口，V4L2_IDENT_SENSOR 不正确，因为它是 0x5648 而不是 0x5647，如果按原样使用，则永远不会检测到相机，因为在sensor_detect() 中进行了此检查：
#define V4L2_IDENT_SENSOR 0x5648static int sensor_detect(struct v4l2_subdev *sd) { data_type rdval; unsigned int SENSOR_ID = 0; sensor_read(sd, 0x300A, &rdval); SENSOR_ID |= rdval; SENSOR_ID |= (rdval << 8); sensor_read(sd, 0x300B, &rdval); SENSOR_ID |= (rdval); sensor_print("V4L2_IDENT_SENSOR = 0x%x\n", SENSOR_ID); if (SENSOR_ID != V4L2_IDENT_SENSOR) { sensor_print("ov5648 %s error, chip found is not an target chip", __func__); //return -ENODEV; } return 0; }- 驱动程序将其传感器报告为“ov5648_mipi”，如果您将相同的内容放入 DTS 中，这并不是什么大问题，但它仍然具有误导性。
#define SENSOR_NAME "ov5648_mipi"一旦这些基本问题得到解决，驱动程序就会加载并创建 /dev/video 节点，就像我的驱动程序一样。 但我们最终在camerademo应用程序上遇到了完全相同的错误：
唯一的区别是由于缺少配置文件而导致 ISP 上出现一些错误行，但由于我们的错误与超时相关，因此它不应受到任何“像素格式”或 ISP 错误的影响。 因此，即使有了这个驱动程序，我们还是回到了原点。我想知道 MLCK 位于相机内部并且未连接到 V851S 是否会导致问题...

我发现 allwinner 提供的文档之一在常见问题解答中提供了有关我所面临的确切问题的信息。 所以我现在会尝试按照其中的说明进行操作。 我似乎需要 mipi 寄存器偏移量才能正确调试，但他们不为 V851S 提供这些偏移量，只为其他芯片提供这些偏移量，而且我在芯片的数据表中没有找到它们，知道我可以从哪里获得它们吗？
