EP405 network interface

EP405 network interface

[Toni Van Remortel]

Hi all,

I cannot get the NIC working on my EP405. I used the ep405_config from
the linuxppc_2_4_devel tree.

This is a part of the output:

...
loop: loaded (max 8 devices)
eth0: No PHY device found.
removing net dev
...

So it seems that the kernel doesn't find the NIC (but it is there, and
working, ep-bootloader can use it to download the image).

Anybody an idea?

I already checked the NIC support, and the onboard-IBM NIC support is
enabled.

Regards,

Did you enable the phy in the Board Control Status Register?

I ended up hard-coding the interface since the 2_4_devel tree was shifting
on EP405 support quite a bit.  Some EP405 boards worked and some didn't.
Once you tell it it definitely has one (unconditionally) it sails along
smoothly.

I also found that booting out of flash does the same thing regardless of
the EP405 board.  I had to initialize the interface via the firmware before
the Linux driver work work.  I wasn't able to hard-code around that one.

Another point to keep in mind - the linux bootloader code will assume clock
rates for everything.  They're not always correct and that screwed up a lot
of things.  You may want to double check those.

How and where?

I found that the PHY address in the manual is 0b00000 and in the code
PPC405_PCI_PHY_MEM_BASE is set to 0x80000000.

You need to look at the board's user manual.  There is a section called
"Board Control and Status Registers"
