I use Nuleo-H743ZI2 evalboard and example LwIP_HTTP_Server_Netconn_RTOS from CubeH7 package.
All necessery files was replaced by your files from "Ethernet Driver Bug-Fixes" package, also all your settings from lwipopts.h and buffors size.
The original example from ST and your example work (main difference is in max speed - ST example achieve max 50mbps), but both have the same problems:
1) connect to netconn http server - ok, then connect to netconn tcp echo server - http server stop ack. Disconnect from echo server - http server start ack again.
2) connect to nectonn tcp echo server - ok, then connect to netconn udp echo server - haard fault on function netbuf_alloc (debug message memp_malloc: out of memory in pool NETBUF)
udpecho_thread(void *arg)
{
struct netconn *conn;
struct netbuf *buf, *tx_buf;
err_t err;
LWIP_UNUSED_ARG(arg);
conn = netconn_new(NETCONN_UDP);
netconn_bind(conn, IP_ADDR_ANY, 7);
LWIP_ERROR("udpecho: invalid conn", (conn != NULL), return;);
while (1) {
err = netconn_recv(conn, &buf);
if (err == ERR_OK) {
tx_buf = netbuf_new(); // <-- tx_buf is NULL
netbuf_alloc(tx_buf, buf->p->tot_len); // <----- crash here,
...
Also after only connect to http server, althoung it works, there are message :
memp_malloc: out of memory in pool TCP_PCB
memp_malloc: out of memory in pool NETCONN
Increasing MEMP_NUM_TCPIP_MSG_INPK and MEMP_NUM_TCP_PCB not helping.
I know there are many bugs possibilities, but all code is based on standard ST/lwip example without any modification except yours. I don't have much experience in lwip so i don't know where to start search problem.
