[ECOS] Changing MAC address

[ECOS] Changing MAC address

[Yuriy Coureelo]

Dear Sir!

I have EB40 with cs8900a ethernet chip.
MAC configured statically, during compilation.

I want to change its MAC address, but dont know how.
I try to call cs8900a_init(), but seems to me, if_detach should be
called too. I cant understand how it works.

Would somebody write a sequence of changing MAC, please.

Sincerely yours
Yuriy Coureelo

I think you can use the
ecos/packages/net/common/current/tests/set_mac_address.c test to "solve"
your problem.

[ECOS] changing MAC address

[Jacek Poplawski]

I was able to make 82545GM ethernet functional in Redboot, I am now able 
to ping or load file via tftp.
Now I want to make it possible to set MAC address from Redboot, because 
in the initial state of hardware - MAC address is filled with 00's.

What is the best way to change MAC address of ethernet controller from 
the command line of Redboot?

Intel 82544 driver contains function "set_mac_address" and it is used in 
ioctl handler, but:
1) it doesn't write to EEPROM, so it changes MAC address only for a 
while - am I right?
2) MAC address is read during the network initialization in RedBoot, 
even if I change it from command line, I will need to ask for BOOTP 
again, right?
