STM32N6570-DK – Ethernet TX Failure & Camera Frame Not Received

Selvarasu_K
Associate II

The FSBL → Application jump is working fine, and the application is running properly from external flash.

However, I am facing the following issues:

Ethernet Issue

  • Ethernet initialization is successful
  • PHY link is UP, but speed is 10 Mbps (Full Duplex)
  • Ping is not working
  • Ethernet TX is failing continuously
  • No UDP data transmission

Camera Issue

  • Camera (IMX335) is detected over I2C
  • Initialization is successful
  • Streaming is started
  • But no frame data is received (first frame timeout)

Support Required

  • How to fix Ethernet bring-up (speed, ping, TX issue)
  • Any example/project for Ethernet + UDP communication
  • Guidance for CSI/DCMIPP camera interface and how to read frame data

    The suggested VENC_RTSP_Server example contains only initialization; full configuration and setup details are not clear & .ioc also missing

These issues are blocking further progress. Kindly provide guidance or reference examples.
