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].
Do you have a working Linux kernel with a working network interface ? The Linux and U-Boot macb driver and PIO configuration is very close, and if you manage to make it work under Linux you'll probably have little trouble finding out the problem.
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.
I don't see what NAND has to do with ethernet here.
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.
Does the board send anything at all ? Try sniffing the net wire (using tcpdump for example).
Also, what cross chain are you using ? I have seen strange network errors when using recent compilers which after investigation were -Os optimisation errors. (using the latest CodeSourcery toolchain for example).
Is there someone out there how has the MII mode working?
If I'm correct, Olimex has. So closer inspection of their code may reveal some information.
Stelian.
