I am testing LwIP on the S32K3. When using iPerf, the transmission aborts after a hundred seconds or so. I'm unsure of the cause, but it seems to be due to a lack of response from both the K3 and the PC, leading to the termination, as shown in the attached imag#SJA1110e.
This is one of the issues. The other problem is that after the transmission aborts, I'm unable to test iPerf again, and there's no response to ping. I've checked the system, and it appears to be running normally.
Please assist me in adjusting the parameters or identifying where to check.
I suspect that the disconnection issue might be related to the SJA1110. Could you assist me in troubleshooting this part of the problem?
The other issue I found is that the system gets stuck during the following check when sending or receiving data.
"Another issue is how to make the SJA1110 blink and display the correct indicator light when transmitting and receiving data?
Attached is the firmware for the SJA1110.
Thank you.
