STM32H743 Ethernet Debugging - PHY Link Status, Bandwidth Testing, Link Drop Detection.

MADHU2
Associate III

Hello ST Team,

I'm implementing robust Ethernet on STM32H743ZI. Need technical guidance on:

PART 1: BANDWIDTH VERIFICATION

Question 1.1: How to verify link speed?

How to check link speed (100 Mbps)?


Question 1.2: Bandwidth testing methodology?

Create a TCP socket, send a large file to the PC?
Expected bandwidth on STM32H743?
Network overhead (TCP/IP stack)?
Optimal packet size for testing?  Also, how can I debug this to check if I am using full bandwidth and if my link is down during transmission?
