ETH LWIP STACK FOR PING OF FOUR IP'S IN STM32H745 IS NOT WORKING.

[syed1]

HI,

As I mentioned in the subject, we are using the LWIP stack for the configuration of four different IP's. The IP's got configured and the issue is while trying to ping all the four IP's the ping is happening only for the three IP's and i will share the snip below for reference's and what need to be done for the reliable ping of all four configured IP'S.So please help us regarding this. And I am working this ETH section on STM32H745 Controller. 

 

Thanks and regards.,

syed.

Hello @syed1 ,

it seems that the ping request on the fourth IP address is timing out because if you can see that the time to get a reply is increasing from one address to the other so I would suggest you write the ping command in a basic script (bash) inserting some delays to see if you are overloading the ICMP implementation to respond to such huge number of requests simultaneously.
