代码功能是创建客户端，静态ip，在407跑通了，但是直接复制移植到429的板子就运行报错，请问可能是啥原因，lwip初始化成功，tcp客户端也初始化成功，之后就运行调试串口打印出这个
Assertion "arp_table.q == NULL" failed at line 369 in ..\LWIP\lwip-1.4.1\src\netif\etharp.c[ i]
那几行代码是
/* 1) empty entry available? */
if (empty < ARP_TABLE_SIZE) {
i = empty;
LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_find_entry: selecting empty entry %"U16_F"\n", (u16_t)i));
} else {
/* 2) found recyclable stable entry? */
if (old_stable < ARP_TABLE_SIZE) {
/* recycle oldest stable*/
i = old_stable;
LWIP_DEBUGF(ETHARP_DEBUG | LWIP_DBG_TRACE, ("etharp_find_entry: selecting oldest stable entry %"U16_F"\n", (u16_t)i));
/* no queued packets should exist on stable entries */
LWIP_ASSERT("arp_table[ i].q == NULL", arp_table[ i].q == NULL); //这里就是369行
/* 3) found recyclable pending entry without queued packets? */
}
