Need help for STM32F4 TCP/IP connection

Hey,

I�m using the STM32F407ZG from the mikroe TFT starter kit. Now I want to get an Ethernet Connection with mikroemedia shield. The Connection should work over TCP/IP and DHCP can�t be used. I�m trying the example from the libstock site but I don�t get a physical Connection at least. I�m using the Net_Ethernet_Intern_STM32 libary from Libstock. When I try to initialize Ethernet then the linker hung up, if I comment it out then it works like before.  Can anybody help me ? Thanks a lot #tcp/ip #stm32 #ethernet

I'm not using mikroemedia or libstock, so probably not much. If I decipher that properly, it hanging up in the reset/init code, probably stuck in a loop if you looked with a debugger. Most such problems relate to the clocking and PHY issues. Generating the correct clocks at 25/50 MHz, and configuring the correct pins for the mode used.
