Here's the method I use to bring up our new DM355 based boards. These
commands write a MAC address into the EEPROM of the DM9000.
On boot, hit a key to get the u-boot command line. Copy and paste the
following lines, but note you should paste them separately one at a
time, the datasheet requires a delay between setting up a write and
executing it. Although, the delay specified is 500us so it might be OK
to just paste the whole lot in.
In bold are the digits that are programmed in for the MAC address. The
bytes are in left-to-right order. You should use your own MAC addresses,
you can get them officially assigned. The ones in this example are ones
I made up for testing! Note that there are restrictions on the format of
the first byte, certain patterns indicate brodcast addresses and stuff.
These commands assume the DM9000 is mapped to the same address space as
on the EVM.
# write 06:06 as first two bytes of MAC address
mw.b 0x4104000 0C; mw.b 0x4104002 00; mw.b 0x4104000 0d; mw.b 0x4104002

# wait 500us here
mw.b 0x4104000 0b; mw.b 0x4104002 0
# write 0b:0b as next two bytes of MAC address
mw.b 0x4104000 0C; mw.b 0x4104002 01; mw.b 0x4104000 0d; mw.b 0x4104002

# wait 500us here
mw.b 0x4104000 0b; mw.b 0x4104002 0
# write 01:01 (or whatever) as last two bytes of MAC address
mw.b 0x4104000 0C; mw.b 0x4104002 02; mw.b 0x4104000 0d; mw.b 0x4104002

Hi Phil,
Your observation is correct.
Any idea how can go though this problem?
Regards,
Jitendra

Hi,
The problem is going to be related to this.....
dm9000 Ethernet Driver
eth%d: Invalid ethernet MAC address. Please set using ifconfig
eth0: dm9000 at c7862000,c7864002 IRQ 45 MAC: ff:ff:ff:ff:ff:ff
No amount of unplugging the RJ45 is going to help in this case
;-)

Subject: RE: DM355:Unable to boot kernel
The DHCPing switches are sometimes close switches or something
happens when we use DHCP - either at the board or at switch.
When I faced a similar problem I just disconnect and reconnect
the RJ45 and then it works with DHCP.
I may not make sense.. but I have faced a similar problem and it
works after reconnecting
Cheers,
Deepak

Subject: DM355:Unable to boot kernel
Hi all,
I am using DM355 based custom board.
I am able to bootup the kernel using static ip but fail with
DHCP enable.
Logs of kernel bootup message with DHCP enable is as shown
below:
