    Camera doesn't work with CYUSB3014

    XiGS_1880821

      Hello, everybody!

       

      我参考AN75779文档,连接摄像头,但没有成功;
      I referred to the AN75779 document to connect the camera, but failed;

       

      1、因为摄像头要用到IIC接口,不知道是否会与EEPROM存储程序的芯片冲突?
      1. Because the camera needs to use IIC interface, So I wonder whether it will conflict with the chip of EEPROM storage program.

       

      2、采用SPI芯片M25P40,程序下载成功,但是用SPI模式无法启动?
      2. Using SPI chip M25P40, the program was successfully downloaded, but could not be started with SPI mode?

       

      PIN Connect:(camera-->CYUSB3014)
      LV --> CTL11
      FV --> CTL12
      D0-7 --> DQ0-7
      PCLK --> PCLK
      SCL --> SCL
      SDA --> SDA
      RESET --> CTL5
      PWN  --> GND

          >> 请问下 你是否了解 I2C 协议是否允许 一个 master,多个 slave?

          >>请详细描述下 固件下载和启动的细节,“无法启动” 这样的表述让人难以清楚理解问题点。或者,将固件下载到 RAM里看是否能够成功枚举。
