So have you stepped into that function to see where, exactly, it gets stuck?

And seen the guide on getting debug info out of LwIP?

Hi, it is getting stuck in the while loop in low_level_output. Here is my stack trace.

12java_0-1752502014064.png

 

if (HAL_ETH_Transmit_IT(&heth, &TxConfig) == HAL_OK) {
 while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK)

 {
 }

 HAL_ETH_ReleaseTxPacket(&heth);
 } else {
 pbuf_free(p);
 }

 

I will look into the LwIP debug info guide now
