I followed you instructions and then changed library version in project.ioc. Reopened project, regenerated code and it seems like I'm using 1.28.1. Edit: Opened project in CubeMx, changed package version and regenerated code. Now .ioc won't open in STM32CubeIDE
Unfortunately still tcip_ip thread lock up in waiting for TxPktSemaphore in lol_level_output. I fill further investigate it and report on github. Everything worked fine until I've enabled HTTPD (just static). After that following steps can lock ethernet outpu:
1. Reset device
2. Ping device (just to test it works) -> works perfectly
3. send Get response -> HTTPS logs shows that everything is okey and it send reponse (it doesn't)
4. tcp_ip thread locked while waiting for TxPktSemaphore in low_level_output function.
static err_t low_level_output(struct netif *netif, struct pbuf *p)
{
uint32_t i = 0U;
struct pbuf *q = NULL;
err_t errval = ERR_OK;
ETH_BufferTypeDef Txbuffer[ETH_TX_DESC_CNT] = {0};
memset(Txbuffer, 0 , ETH_TX_DESC_CNT*sizeof(ETH_BufferTypeDef));
for(q = p; q != NULL; q = q->next)
{
if(i >= ETH_TX_DESC_CNT)
return ERR_IF;
Txbuffer[i].buffer = q->payload;
Txbuffer[i].len = q->len;
if(i>0)
{
Txbuffer[i-1].next = &Txbuffer[i];
}
if(q->next == NULL)
{
Txbuffer[i].next = NULL;
}
i++;
}
TxConfig.Length = p->tot_len;
TxConfig.TxBuffer = Txbuffer;
TxConfig.pData = p;
pbuf_ref(p);
if (HAL_ETH_Transmit_IT(&heth, &TxConfig) == HAL_OK) {
while(osSemaphoreAcquire(TxPktSemaphore, TIME_WAITING_FOR_INPUT)!=osOK) //LOCK wait forever
{
}
HAL_ETH_ReleaseTxPacket(&heth);
} else {
pbuf_free(p);
}
return errval;
}
