Hi,

I connected the ethernet port of the STM32F10C-Eval to my pc using an ethernet cable. But the led of the ethernet port is not blinking which means that the connection is not detected. I have changed the cable but nothing is happening. What  could be wrong? Thank you.

So what happens if you DO initialize the ETH/PHY? It's a synchronous part so it's highly likely to need a clock to do anything. So load up some demo/example code which supports Ethernet and TCP/IP

Ok, that's a decision you'll have to own, and use your skills as a programmer to port some Ethernet code to the platform of your choice.

Likely because you need to have the PHY interrupt when the connection changes, and renegotiate the connection. Most simple examples set up the PHY/Connection once at initialization.

MII_INT connects to EXP_IO8 (i2c IO Expander) The code in STM32F107_ETH_LwIP_V1.0.0\Utilities\STM32_EVAL\STM3210C_EVAL\stm3210c_eval_ioe will need a lot of work.
