Hi,
I'm able to boot Linux 2.6 on ML403 board (with a ramdisk file system).
However, during the kernel booting, it complains that "No network devices
available," So I figured I probably didn't enable the ethernet driver in the
kernel.
>From doing "make menuconfig", under "Device Drivers" --> "Network device
support" --> "Ethernet(10 or 100Mbit)", I checked the box of both "Ethernet
(10 or 100Mbit)" and "PowerPC 4xx on-chip Ethernet support." I then
save/exit the menuconfig to compile the kernel again. I've attached the
error output at the bottom.
The problem is that I don't have any define in my .config file that matches
"CONFIG_405GP", "CONFIG_405GPR" or "CONFIG_405EP" in the
/drivers/net/ibm_emac/ibm_emac.h file, so it complains that I might not have
correct defines.
1st question: Which one of the CONFIG_405xxx should I use? I was searching
around but couldn't find an answer, but my intuition tells me that it should
probably be CONFIG_405GP.
2nd question: So I decided to try with CONFIG_405GP just to see what
happens. However, some compilation errors were still there. And it complains
about "dereferencing pointer to incomplete type". Does anyone have any
experience working with this driver and perhaps found that there's an error
in the kernel for this driver?
Thanks,
Aleck
