JetPack Versions

NVIDIA JetPack (Jetpack 5.1.2 or Jetpack 6.0 ) is the official software development kit (SDK) for the Jetson series of development boards. It includes the operating system, drivers, CUDA, cuDNN, TensorRT, and other development tools and libraries. Each JetPack version typically corresponds to a specific Jetson Linux version (formerly known as L4T - Linux for Tegra).

36.4.3: L4T R36.4.3 (Jetpack 6.2)
36.4: L4T R36.4 (Jetpack 6.1)
36.3: L4T R36.3 (Jetpack 6.0)
35.4.1: L4T R35.4.1 (Jetpack 5.1.2)

2. Camera Integration with Customer's Self-developed Platform

For customers with their own deserializer who want to adapt our camera (serializer) to their platform, detailed technical coordination is required.

The diagram illustrates the communication architecture between a camera and controller system. It shows how data flows from the Sensor/ISP through the Serializer on the Camera side, across to the Deserializer and SOC on the Controller side. The system utilizes Fsync signals for synchronization and MFP7 interfaces for control. This architecture is essential for proper integration of SENSING cameras with customer-developed platforms.

Step 1: Link Register initialization

SENSING will provide:

Serializer and Deserializer Configuration
- Register configuration for the camera module-Getting Camera Information
- I2C communication protocol details
Link Status Troubleshooting Guide
- Link training parameters
- Error detection settings

tip

Please refer to the software flow and demo code below to develop your driver code.

Software Development

Driver Development:

/* Example code for MAX9296 I2C initialization */
#define MAX9296_I2C_ADDR 0x90 // 8-bit address

int max9296_init() {
    // Initialize I2C bus
    i2c_init();
    
    // disable MIPI output
    i2c_write(MAX9296_I2C_ADDR, 0x0313, 0x00);
    delay_ms(100);
    // Configure link settings for GMSL2 (6Gbps)
    i2c_write(MAX9296_I2C_ADDR, 0x0001, 0x02);

    // Configure linkA and linkB settings for GMSL2 selection (default value)
    i2c_write(MAX9296_I2C_ADDR, 0x0006, 0xC0);
    
    // Configure MIPI rate 1200Mbps
    i2c_write(MAX9296_I2C_ADDR, 0x0320, 0x2C); 
    
    // enable MIPI output
    i2c_write(MAX9296_I2C_ADDR, 0x0313, 0x02);
    
    return 0;
}

Camera Configuration:

/* Example code for   initialization */

#define MAX9295_I2C_ADDR 0x80 // 8-bit address

int camera_init() {
    // Initialize deserializer first
    max9296_init();
    
    // Reset ISP through MAX9295A
    i2c_write(0x80, 0x02BE, 0x10); // MFP0 high
    // 
    i2c_write(0x80, 0x0057, 0x12); 
    i2c_write(0x80, 0x005B, 0x11); 
    //  Configure datatype  RAW10
    i2c_write(0x80, 0x0318, 0x6B); 

    //  camera trigger  MFP7  low to  high
    i2c_write(0x80, 0x02D3, 0x00); // MFP7 low
    delay_ms(300);
    i2c_write(0x80, 0x02D3, 0x10); // MFP7 high

    return 0;
}

Integration Steps

BSP Integration:
- Modify the device tree to include the CSI interface configuration
- Add camera driver to kernel build configuration
- Configure media controller pipeline for the camera
Application Development:

/* Example code for capturing camera frames */
#include "camera_api.h"

int main() {
    // Open camera device
    int fd = open("/dev/video0", O_RDWR);
    if (fd < 0) {
        perror("Failed to open camera device");
        return -1;
    }
    
    // Configure video capture format
    struct v4l2_format fmt = {0};
    fmt.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
    fmt.fmt.pix.width = 1920;
    fmt.fmt.pix.height = 1536;
    fmt.fmt.pix.pixelformat = V4L2_PIX_FMT_RAW10;
    
    if (ioctl(fd, VIDIOC_S_FMT, &fmt) < 0) {
        perror("Failed to set format");
        close(fd);
        return -1;
    }
    
    // Request and map buffers
    // ... (buffer setup code) ...
    
    // Start streaming
    // ... (streaming code) ...
    
    // Capture and process frames
    // ... (frame processing code) ...
    
    // Cleanup
    close(fd);
    return 0;
}
