Hi All,
I have been struggling the last week to get the macb Ethernet driver in MII mode.
[in short] I have communication over the MDIO interface, my activity led blinks but no ehternet.
[the long story] I have a custom board build out of the schematics of the AT91SAM9260EK board. On my boar I did not use the DM9161 but the KS8721chip. On the ATMEL board the PHY works in RMII mode, on my board I used MII mode like this board from OLIMEX [1].
Olimex was kind enough to make Uboot nandflash build working with there board, And deliver sources I cant compile, due to an error: Hardware float vs software float. But I want a dataflash version because I am using a BGA chip with nandflash bug.
In my current setup I use the latest git of the AT91 tree with the following defines: #define CONFIG_MACB 1 #define CONFIG_MII 1 #undef CONFIG_RMII #define CONFIG_NET_MULTI 1 #define CONFIG_NET_RETRY_COUNT 5000 #define CONFIG_RESET_PHY_R 1
With this config I have the MDIO interface working, when I try to ping or TFTP I only get time outs / host not alive errors.
Is there someone out there how has the MII mode working?
Best regards,
Sander
