V851S tina linux ov5647 驱动程序没有 dmesg
-
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：

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。

@kanken6174 在 V851S tina linux ov5647 驱动程序没有 dmesg 中说：
我正在从头开始重写它。
你好
当我在 linux 中开发传感器驱动程序时，我使用特殊代码将 ioctl 添加到 V4l2 驱动程序、VIN 驱动程序和传感器驱动程序中。
此 ioctl 用于直接从用户空间写入和读取传感器寄存器。 这种方法大大加快了开发速度， 因为从用户程序测试传感器寄存器编程的各种选项比从驱动程序测试要容易得多。 -
@alb702 这是个好建议，我可能会这样做，因为传感器由于某种原因仍然没有发送其 mipi 帧......它至少会让调试更容易
-
ov5647 这个型号的摄像头并没有适配，SDK也没有支持。
请参考V85x的摄像头支持手册选择适配的摄像头。这里推荐已经量产的产品使用的GC2063，GC2083，GC4663这三款摄像头，已经经过严格的测试与调试，可以达到最佳画质和分辨率
-
@awwwwa 我知道 OV5647 不支持开箱即用，我想通过修改内核中已有的 OV5648 驱动程序来为其制作一个驱动程序。 我在驱动程序中仔细设置了 I2C 上每个必需的寄存器，其方式类似于 linux 内核 6.1 驱动程序处理它的方式（因为 linux 6.1 内置了 0V5647 驱动程序）。
我按照 allwinner 提供的在 tina-linux 下移植相机的指南进行操作，我的驱动程序成功加载、发送相机配置并正确报告。 mipi-csi 时钟和数据通道上也有活动（但它们太快了，我无法正确调试），这表明相机确实对其新配置做出了反应。
现在我当然可以选择支持更好的 GC 相机，但这不是目标，我正在尝试在这个平台上支持 rapsberry pi 1.3 相机。 我这样做是因为许多廉价模块都采用这种 15 针外形尺寸，但 GC 系列相机很难找到这种格式。
接下来我可能会尝试 IMX219（树莓派相机 V2），因为当前的 4.9 内核中已经有它的驱动程序，但目前 OV5647 仍然超时与camerademo，并且没有太多关于应该采取的行动过程的信息 在这种情况下，请参见 PDF 的常见问题解答。
您认为有什么东西可能会破坏我的 allwinner Eyesee 框架方面的驱动程序吗？ 我还必须考虑硬件不兼容的可能性，并验证我猜的所有 mipi 逻辑级别...

@yuzukitsuru 感谢该驱动程序，但我之前已经尝试过但没有成功，它有很多问题（如果您在本文中引用 ov5647_mipi.c 驱动程序），例如：
- 设备ID和传感器名称错误：
#define SENSOR_NAME "ov5648_mipi" #define V4L2_IDENT_SENSOR 0x5648应该
#define SENSOR_NAME "ov5647_mipi" #define V4L2_IDENT_SENSOR 0x5647- 读取CHIP_ID的方式也是错误的，导致读取的是0x5657而不是0x5647
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);应该
data_type rdval, rdval2; unsigned int SENSOR_ID = 0; printk(KERN_WARNING "entering sensor_detect\n"); sensor_read(sd, CHIP_ID_ADDR, &rdval); sensor_read(sd, CHIP_ID_ADDR_L, &rdval2); SENSOR_ID = (rdval << 8) | rdval2; sensor_print("V4L2_IDENT_SENSOR = 0x%x\n", SENSOR_ID);- 检测时似乎根本没有给相机加电，所以它永远找不到它（我必须在 INIT 函数中添加对传感器电源的调用才能检测到我的）
static int sensor_init(struct v4l2_subdev *sd, u32 val) { int ret = 0; struct sensor_info *info = to_state(sd); printk(KERN_WARNING "entering sensor_init\n"); sensor_print("sensor_init\n"); sensor_power(sd, PWR_ON); //added总体而言，这个驱动程序似乎是基于 OV5648.c 的，该驱动程序已经存在所有这些问题，您是否真的让它在某个时刻与 OV5647 一起工作，或者它只是一个草案？
-
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......

这是启动日志：
boot.log -
@kanken6174 在 V851S tina linux ov5647 驱动程序没有 dmesg 中说：
VIN_ERR
错误
[ 106.661031] [VIN_ERR]vin is not support this pixelformat
表示 VIN 驱动程序不支持为此传感器模式设置的像素格式
确保具有此名称的格式已在 VIN 驱动程序源中列出
-
@alb702 我在驱动程序源代码和camerademo命令中尝试了许多不同的像素格式，但它总是最终无法实际工作并给出某种形式的错误。 除了 RGGB8 之外，相机不支持其他格式，当我使用 RGGB8 时，camerademo 会查询传感器的图像，这意味着它至少可以工作到那时。
然后等待帧返回超时，我仍在尝试理解原因，但显然存在相机配置方式或 allwinner 驱动程序期望如何接收帧的问题。如果这是图像格式的问题，我不会收到这种特定类型的错误：
-
@kanken6174 你好，请问这个问题解决了吗？我在添加调试OV9734的摄像头驱动也遇到了这个问题？请问有什么调试的思路吗？
-
@j_biao 目前我还无法让它发挥作用，我仍然停留在与以前相同的位置。 我购买了一台高速逻辑分析仪来尝试看看 mipi 总线上发生了什么。
看起来 mipi 通道的行为根本不像 mipi 通道，这看起来像并行 csi 数据（如果有的话）（时钟通道应该是不同的，但它们不是？）...这很奇怪，因为我仔细检查了两次和三次 我的 i2c/CCI 配置和所有正确的配置应发送到 OV5647 以进入 mipi 模式，而不是并行 csi 模式。
我将尝试获取树莓派 3 来调试它如何设置相机并查看 I2C 和 MIPI 方面的任何差异。
