@flaty
您这个截图的镜像是MV和RAW系列的。
请参考这个链接中的镜像。

@veye_xumm 我也得觉得不对，IMX385 veye系列的最新的驱动是哪个，是1.7下的吗

veye_xumm

@flaty 驱动源码你直接用github最新的就行。

flaty

@veye_xumm 编译错误我把信息发给您看一下，是驱动里面的结构体

一下是内核配置
============Start building kernel============
TARGET_ARCH =arm64
TARGET_KERNEL_CONFIG =rockchip_linux_defconfig
TARGET_KERNEL_DTS =roc-rk3588s-pc-mipi101-BSD1218-A101KL68
TARGET_KERNEL_CONFIG_FRAGMENT =rk3588_linux.config firefly-linux.config

[0_1756784079945_log.zip](正在上传 100%) 这个是完整的编译log，您看一下，我使用firefly最新的SDK 进行的编译，采用5.10的内核

veye_xumm

@flaty
参见代码的注释，你的内核缺少这个接口，需要注掉这个函数。

flaty

@veye_xumm 您这边适配过 SDK1.4.0G 这个版本吗 firefly

veye_xumm

@flaty 可以的。

flaty

@veye_xumm dts 参考这个可以吗？https://github.com/veyeimaging/rk35xx_firefly/tree/main/linux/drivers/rk358x

veye_xumm

@flaty 就是这个。

flaty

@veye_xumm zhge dsi的头您看有问题吗检测不到相机，
#include "roc-rk3588s-pc.dtsi"

//#include "rk3588-roc-pc-cam-8ms1m.dtsi"

//open this line to enable fpdlink-III link
//#include "rk3588-roc-pc-fpdlink-90ub954.dtsi"

//open this line to enable v-by-one hs link

#include "roc-rk3588s-pc-v10-diff.dtsi"
#define WHICHDSI 0 /* dsi0 = 0,dsi1 = 1*/

veye_xumm

@flaty
正常来说，你只要在这个文件的基础上做如下修改：
//open this line to enable v-by-one hs link
//#include "rk3588-roc-pc-vbyone-overlay.dtsi"
#include "rk3588-roc-pc-cam-veyecam2m.dtsi"
//#include "rk3588-roc-pc-cam-veyemvcam.dtsi"

@veye_xumm 我再试一下吧，不知道咋回事，，，编译什么都没问题

以上电源的错误，但是ls /dev/video0 可以看到设备了

veye_xumm

@flaty 这些报错都不用管。我们的模组不需要这些供电。

flaty

@veye_xumm 测试出图像了，搞定了，谢谢

veye_xumm

@flaty 不客气。

flaty

@veye_xumm 现在遇到个新的问题，我不知道是板子硬件支持，我是用DMABUF 作为V4L2的qbuf, 但是返回错误 Failed to queue buffer: Invalid argument，您看一下我这部分代码，是不是该驱动支持，
//将缓冲区注册到摄像头
struct v4l2_buffer buf={0};
struct v4l2_plane planes[1]={0};
buf.index =0;
buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
buf.memory = V4L2_MEMORY_DMABUF;
buf.length = 1;
buf.m.planes = planes;
planes[0].m.fd = frame_buffers[i].dmabuf_fd;
planes[0].length =buffer_size;

    if (ioctl(cam_fd, VIDIOC_QBUF, &buf) < 0) {
        perror("Failed to queue buffer");
        return -1;
    }

@flaty 建议您参考一下yavta的源码。git clone https://github.com/veyeimaging/yavta.git

flaty

@veye_xumm 我看了那个源码内存采用普通的内存，我希望的是用 drm 或dmaheap 的，这样可以实现零copy
