Думаю из-за SPI, но никак победить не могу эту проблему, уже мучаюсь 2 дня с этим 
Вот как делаю:

void network_init() {
uint8_t bufSize[] = {2, 2, 2, 2};
reg_wizchip_cs_cbfunc(wizchip_select, wizchip_deselect);
reg_wizchip_spi_cbfunc(wizchip_read, wizchip_write);
wizchip_init(bufSize, bufSize);
wiz_NetInfo netInfo = { .mac = {0x00, 0x08, 0xdc, 0xab, 0xcd, 0xef}, // Mac address
.ip = {192, 168, 1, 123}, // IP address
.sn = {255, 255, 255, 0}, // Subnet mask
.gw = {192, 168, 1, 1}}; // Gateway address
wizchip_setnetinfo(&netInfo);
wizchip_getnetinfo(&netInfo);
delay_ms(2000);
uint8_t *mac = netInfo.mac;
UPRINT("MAC: %02X:%02X:%02X:%02X:%02X:%02X\r\n", mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);
