Need Suggestions: Achieving 60 FPS (1920x1200) Camera Capture on Verdin-AM62

Technical Support

Hi everyone,

I’m currently using a Verdin-AM62 (1 GB, non-WiFi) module with a USB camera, and I’m getting only around 5–6 FPS when capturing video at a resolution of 1920×1200 using V4L2 on Linux.

I’d like to achieve at least 60 FPS at this resolution.

Could you please help with a few questions:

  1. Would switching from a USB camera to a CSI camera help me achieve higher frame rates (closer to 60 FPS)?
  2. Is the Verdin-AM62 capable of handling this performance, or would you recommend a different Toradex SoM that’s better suited for high-frame-rate camera applications?
  3. If possible, please suggest a camera module (CSI or USB) that works well for this use case.

Thanks in advance for your time and suggestions!

Best regards,
uday

Camera Performance Analysis for Verdin AM62

CSI vs USB Camera Performance

Switching from a USB camera to a CSI camera would likely help you achieve higher frame rates(1)(2). CSI cameras connect directly to the SoM’s MIPI CSI interface, providing a dedicated high-bandwidth connection that bypasses the USB subsystem bottleneck(1)(2).

The Arducam CSI Camera Module 5MP OV5640 is supported on the Verdin AM62 and offers up to 1920×1080 resolution at 30 FPS(1). This camera module features:

  • MIPI CSI-2 interface for direct connection(1)
  • Output formats: 8-/10-bit RGB RAW, RGB, YUV, JPEG(1)
  • Max resolution: 2592 x 1944 pixels(1)
  • Sensor image area: 6.287mm x 4.712 mm(1)

Verdin AM62 Capabilities

Your Verdin AM62 Dual 1GB module includes(3):

  • 2x Cortex-A53 cores running at 1.4GHz(3)
  • MIPI CSI camera interface support(3)
  • No GPU (GPU is only available on Quad variants)(3)

The lack of GPU acceleration may limit your ability to achieve 60 FPS at 1920×1200, especially for video processing tasks that benefit from hardware acceleration(3).

Alternative SoM Recommendations

For high-frame-rate camera applications, consider the Verdin AM62P, which offers:

  • More powerful GPU with 50 GFLOPs of theoretical performance(4)
  • Triple display controller supporting up to 3 display outputs(4)
  • Enhanced graphics processing capabilities for camera applications(4)
  • Same MIPI CSI interface compatibility(4)

Camera Module Recommendations

CSI Camera Options:

  1. Arducam CSI Camera Module 5MP OV5640(1)
    • Fully supported with device tree overlays(1)
    • Compatible with Verdin Development Board, Mallow, and Dahlia carrier boards(1)
    • Maximum performance: 1920×1080 at 30 FPS(1)

Implementation Steps:

To use the Arducam camera, you’ll need to:

  1. Apply the device tree overlay(1):
# fdt_overlays=verdin-imx8mp_hdmi_overlay.dtbo verdin-imx8mp_dsi-to-hdmi_overlay.dtbo verdin-imx8mp_spidev_overlay.dtbo verdin-imx8mp_ov5640_overlay.dtbo

(1)

  1. Test with GStreamer(1):
# gst-launch-1.0 -v v4l2src device=/dev/video3 ! video/x-raw ! videoconvert ! waylandsink

Performance Considerations

For 60 FPS at 1920×1200 resolution, the processing requirements may exceed what the Verdin AM62 (without GPU) can handle efficiently. The Verdin AM62P with its enhanced GPU capabilities would be better suited for such demanding camera applications(4).
