Сделал диспетчер задач (собственно, оформил FreeRTOS-овский как надо). Если фладить так:
Код
cat /dev/random | nc -u 172.16.0.100 22222
, даже не на открытый порт (например 22221), то падает (через 3-4 секунды с момента старта железки, когда флад идёт, либо во время работы железки, с момента запуска скрипта). Посмотрел в Wireshark — порядка 10к пакетов в секунду отправляется с машины (фреймы по 1514 байт).
Задача udp выгдялит так:
CODE
static
void udpTestTask(void * pvParameters) {
while (inet_setup == 0) {
vTaskDelay(1000 / portTICK_RATE_MS);
}
printf("udpTestTask started\r\n");
struct netconn * conn;
struct netbuf * buf;
err_t err;
(void)err;
conn = netconn_new(NETCONN_UDP);
netconn_bind(conn, IP_ADDR_ANY, 22222);
for (;;) {
err = netconn_recv(conn, &buf);
printf("rcvd length = %u\r\n", buf->p->tot_len);
netbuf_delete(buf);
}
}
lwIP настроен так:
CODE

Выдаёт задачка:

static

for (int i = 0;; ++i) {
printf("%d\r\n", i);
printf("memory gap = %u\r\n", xPortGetFreeHeapSize());

}
}
}
Мало того, что не отвечает на все пакеты, так ещё и assertion failed без пояснений =(.
