Full duplex, MDIO and both Ethernet in MPC8272ADS

Full duplex, MDIO and both Ethernet in MPC8272ADS

[alebas]

Hi to all,

As long as I have seen (tested and surfed in the code), current
linuxppc_2.4.26_devel support for MPC8272ADS board is limited to one PHY,
without MII management support and the interface is always configured as Half
Duplex. Unfourtunately, this is little useful for me, as long as i am trying to
set up a bridge between both interfaces.

I have been also testing the Linux Reference Design, from Arabella SW, which, as
long as I have seen, has support for both PHYs, MII management and Full Duplex.

So, is there any plan to merge any of Arabella's changes into the ppc tree? Or
is there anyone currently working on that ethernet stuff for current 2.4.26
tree? Is  it planned to provide a patch soon?

Best regards,

Alex.

Have you asked Arabella what their plans are to submit changes to the
PPC tree? They would be the maintainer of those changes so it's up
to them. It should go into 2.6 first, though, and could go into a
PPC 2.4 tree. Marcelo's 2.4 tree is not taking new features.

I use the fcc enet driver and a dual port phy using the fcc driver's mii
implementation on a 8270, but on a propietary board design.

Hi,

After your reply I checked my work. I upgraded into the last version of
linuxppc-2.4 from ppc.bkbits.net, which is version 2.4.27 of the kernel and
1.22 of the fcc_enet driver, and then MII management and Full-duplex seemed
to work.

However, the second interface were still not working. I have seen that one
reason could be the second PHY not being enabled during device init
(BCSR3_FETHIEN2), while the first PHY were. I changed it and now, i think it
works. At least, it answer and sends echoes.

Thanks
