Hello,

Until today we are using our 852T module in 10M ethernet mode. But now we are modifying our hardware to support 100M ethernet.

The uboot is configured with the

#define CONFIG_FEC_ENET 1 #define CONFIG_FEC_ETH 1 #define FEC_ENET 1 #define FEC_INTERRUPT SIU_LEVEL5 #define CFG_DISCOVER_PHY 1

and this configuration is working on the 10M FD/HD ANEG mode

but now we have changed the configuration hard wired pins of the AMD79c874vc phy to use

All capabilities ANEG mode

but then uboot fails to use ethernet

What can we do?

Best Regards Yigit Can
