DS-207 network failure

[Julian Coleman <jdc%coris.org.uk@localhost>]

Hi,

I've recently acquired a Synolgy DS-207, and had problems getting altboot
to load the kernel - the same problems as the "Synology CS 407e: altboot
fails to load installer" thread from the mail archive.  To add a little
bit to the that thread:

Yes, PPCBoot seems to support TFTP booting.  However, mine sets its MAC
address to 00:11:22:33:44:54 (and not the 00:11:32:01:95:49 that the chip
has).  But, I can set this address on my DHCP/TFTP server and it works:

But, this fails for me:

  _MPC824X > go 100000 nfs:netbsd
  ## Starting application at 0x00100000 ...

Nothing more is printed.  If I use kermit to tranfer altboot.bin, then I
can run altboot, but that fails to transmit any packets.  I have tried it
with both a 1Gbps and a 100Mbps link.  It reports the correct link speed
both times (1000Mbps-FDX or 100Mbps-FDX) but always "xmit failed".  No
packets are transmitted on the wire either:

  _MPC824X > go 1000000 nfs:netbsd
  ## Starting application at 0x01000000 ...

At this point, the link light on the switch is lit, and it stays lit through
the "xmit failed" lines, so it seems that the phy configuration is correct.

Thanks,
