TMS320F28388D: Ethernet Disconnects After a While and Never Reconnects

Tool/software:

Hi,

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1378159/tms320f28388d-ethernet-disconnects-after-a-while-and-never-reconnects

I can ask my other questions here since the topic on the link is closed.

Shouldn't sys_check_timeouts() be used in TCP? If not, how does it keep track of time?

while (1)
{
sys_check_timeouts();

}
