Hi all,
i've successfully installed kamikaze trunk (r10141) on a wg302 but i'm having troubles with ethernet.

Although the microcode seems to loads, eth0 is unusable and i'm getting a flood of the following kernel message: "eth0: MII read failed".
Mac address of eth0 is null (00:00:00:00:00:00) but i can configure the device with ifconfig.

Another strange thing is that the image seems not contains kmod-ixp4xx-npe (selected from kernel-modules -> network devices) and i'm not getting the following messages at boot time:

ixp4xx_mac driver 0.3.1: eth0 on NPE-B with PHY[0] initialized
ixp4xx_mac driver 0.3.1: eth1 on NPE-C with PHY[1] initialized

I'm following this (http://wiki.openwrt.org/OpenWrtDocs/Har … gear/WG302) guide.

I think you have to skip the following NPE-B loading through tftp step.

    * load microcode from tftp server 

RedBoot> load -r -b %{FREEMEMLO} NPE-B

    * write microcode to flash. Attention: Be sure to specify the corrent startaddress 0x50780000=startaddress of root partition plus size of root partition (0x620000, see above), as redboot otherwise places the microcode within the root partition. Bug or feature? 

RedBoot> fis create -f 0x50780000 microcode

The discussion might have continued from here.
