【TOYBRICK】Fedora读取OV9750 MIPI摄像头问题

[复制链接] · 发表于 2020-4-20 10:30:02

按照Wiki上面的说明，自己写了一个小例子，但是运行报错。源代码：

#include <rockchip/rockchip_isp.h>

#include <rockchip/rockchip_drm.h>

extern "C"{

#include <rockchip/rockchip_rga.h>

}



#include <stdio.h>

#include <stdlib.h>

void* engine;

int vidFd;

const char ispNode[] = "/dev/video0";

const char tuningFile[] = "/etc/cam_iq_ov9750.xml";



int main(int argc, char** argv)

{

        unsigned char* data;

        data = (unsigned char*)malloc(1920 * 1080 * sizeof(unsigned char));

        RockchipRga* myRga;



        if(rkisp_start(engine, vidFd, ispNode, tuningFile))

        {

                printf("Error For Init RKISP Start\n");

                return -1;

        }



        myRga = RgaCreate();

        if(myRga == NULL)

        {

                printf("Error For Create Rga\n");

                return -1;

        }



        myRga->ops->initCtx(myRga);



        myRga->ops->setSrcBufferFd(myRga, vidFd);

        myRga->ops->setDstBufferPtr(myRga, data);



        myRga->ops->setDstFormat(myRga, V4L2_PIX_FMT_ARGB32, 1920, 1080);

        myRga->ops->setSrcFormat(myRga, V4L2_PIX_FMT_SGRBG10, 1920, 1080);





        while(true)

        {

                myRga->ops->go(myRga);



        }

｝

求帮忙看一下是什么问题引起的

I2C读写出错。看下是否是接触不良。量下I2C硬件波形是否正常。

请问一下：有在Fedora上读出OV9750的数据吗？
