AM2434: Enet Lwip CPSW Example with Static IP on TMDS243EVM

Hi Team,

I'm writing to report an issue I'm encountering with the Enet Lwip CPSW Example configured with a static IP address in mcu_plus_sdk_am243x_09_01_00_41.

Background

I successfully ran the Enet Lwip CPSW Example with a static IP on the TMDS243EVM using mcu_plus_sdk_am243x_09_00_00_35. In this setup, I have modified code in file lwipcfg.h file as below to set USE_DHCP and USE_AUTOIP as '0':

#define USE_DHCP 0

#define USE_AUTOIP 0

and:

/* #define USE_PCAPIF 1 */
#define LWIP_PORT_INIT_IPADDR(addr) IP4_ADDR((addr), 192,168,3,50)
#define LWIP_PORT_INIT_GW(addr) IP4_ADDR((addr), 192,168,3,1)
#define LWIP_PORT_INIT_NETMASK(addr) IP4_ADDR((addr), 255,255,0,0)

I was able to ping the TMDS243EVM.

Current Issue

When I replicate the same approach (disabling DHCP and AUTOIP in lwipcfg.h) with mcu_plus_sdk_am243x_09_01_00_41, I am unable to ping the TMDS243EVM. 

My test.c file settings are:

#define IP_ADDR_POOL_COUNT (2U)

const ip_addr_t gStaticIP[IP_ADDR_POOL_COUNT] = { IPADDR4_INIT_BYTES(192, 168, 3, 50), /* For NetifIdx = 0 */
IPADDR4_INIT_BYTES(192, 168, 4, 50),}; /* For NetifIdx = 1 */
const ip_addr_t gStaticIPGateway[IP_ADDR_POOL_COUNT] = { IPADDR4_INIT_BYTES(192, 168, 3, 1), /* For NetifIdx = 0 */
IPADDR4_INIT_BYTES(192, 168, 4, 1),}; /* For NetifIdx = 1 */
const ip_addr_t gStaticIPNetmask[IP_ADDR_POOL_COUNT] = { IPADDR4_INIT_BYTES(255,255,0,0), /* For NetifIdx = 0 */
IPADDR4_INIT_BYTES(255,255,0,0),}; /* For NetifIdx = 1 */

The system outputs messages indicating successful initialization of lwIP with the configured static IP (192.168.3.50), but pings to this address fail.
