STM32F407ZGT Ethernet DP83848 RMII "unidentified network"

Question asked by Manoj Prabhakaran R on Apr 11, 2018

Hi , Im working on STM32F407ZGT in my custom made PCB, Im working on Ethernet with DP83848i PHY in RMII mode, I downloaded the STMcube ethernet template code for  DP83848 MII mode, I changed the code according to RMII requirements. But still it is not working, Im seeing my device as "unidentified network" trying to sort, I have to be sure that my code is a working code. STM mcu is successfully communicating to DP83848 registers. Since Im turning LED on when Ethernet is connected. 

 

Regarding Hardware connection, 

50Mhz Osc -> DP X1

Stm TxEn -> DP TxEn

Stm TxD0 -> DP TxD0

Stm TxD1 -> DP TxD1

Stm RxD0 -> DP RxD0

Stm RxD1 -> DP RxD1

Stm CRS_DV -> DP CRS_CRSDV

Stm MDIO -> DP MDIO

Stm MDIO_CLK -> DP MDC

Stm RMII_REFCLK<-DP X1

 

In Code I tried with Static IP

                        MY computer                   STM32F407

ip->                  192.168.0.5                      192.168.0.5 

Mask->             255.255.255.0                  255.255.255.0

gateway->         192.168.0.1                     192.168.0.1

 

After updating the Firmware and connecting Ethernet crossover cable , 

LED_SPEED -> Always LOW (LED ON)

LED_LINK -> Always LOW (LED ON)

LED_ACT->Changing from 3.3 V to 1.8 V

 

Can I get  a example code for LWIP_HTTP_Server_Raw for DP83848 RMII mode.

 

Thanks in advance
