Title: Ethernet Pins on STM32F1xx
Post by: colinbathe on December 14, 2012, 04:07:25 PM

V1.4.1 stm32.c

fnConfigEthernet()


This code sets up the ethernet pins for STM32F1xx processors using the alternative pin set. However, the processor isn't told to remap the ethernet port pins. _PERIPHERAL_REMAP(ETH_REMAP); sorts this.

(probably sorts this - I don't have ethernet working yet...)

Hi Colin

The STM32F1xx code performs the following remapping as first action:

    _PERIPHERAL_REMOVE_REMAP(MII_RMII_SEL);                              // select MII interface mode rather than RMII
    _PERIPHERAL_REMAP(ETH_REMAP);                                        // remap certain MII pins (PD8:PD9:PD10:PD11:PD12)

The version supports only MII mode.

Since you are working on an alternative for RMII mode for the STM32F1xx it may be that you have a different initialisation there.

Regards

Mark

Yep my mistake. Wasn't reading the code correctly.
