And you have to add some pins configuration due to fact that
STM32F4DISCOVERY board
doesn't any network interface.
In packages/hal/cortexm/stm32/stm32f4discovery/current/include/plf_io.h
please add such lines:
//=============================================================================
// Custom Ethernet pin mappings
#define CYGHWR_HAL_STM32_ETH_MII_TX_EN CYGHWR_HAL_STM32_PIN_ALTFN_OUT(
B, 11, 11, PUSHPULL, NONE, AT_LEAST(50) )
#define CYGHWR_HAL_STM32_ETH_MII_TXD0 CYGHWR_HAL_STM32_PIN_ALTFN_OUT(
B, 12, 11, PUSHPULL, NONE, AT_LEAST(50) )
#define CYGHWR_HAL_STM32_ETH_MII_TXD1 CYGHWR_HAL_STM32_PIN_ALTFN_OUT(
B, 13, 11, PUSHPULL, NONE, AT_LEAST(50) )
In packages/devs/eth/phy/current/cdl/phy_eth_drivers.cdl add missing PHY chip:
cdl_option CYGHWR_DEVS_ETH_PHY_LAN8720A {
display "SMSC LAN8720A"
flavor bool
default_value 0
compile -library=libextras.a LAN8720A.c
description "
Include support for SMSC LAN8720A"
}
and finally add new PHY i.e LAN8720A.c into directory ->
packages/devs/eth/phy/current/src
if you will have additional problems please ask I have already brought
up network interface on
STM32F4DISCOVERY + DM-STF4BB (AFAIK this is original name of base
board from Embest, now
as I see it's called STM32F4DIS-BB).
Best regards,
jerzy
