[U-Boot-Users] NIOS port at Stratix DevKit: distinctions betw een bdi and env

[Scott McNutt]

Hi Stephan,

I'm glad to hear other Nios users are discovering u-boot :-)
U-Boot and Nios is a great combination!

Looks like I screwed up the call sequence in lib_nios/board.c ... the
code is calling getenv("ethaddr") prior to env_init() -- must have been
a late night ;-)

The fields that depend on an initialized environment should be
initialized _after_ calling the routines in init_sequence ... which
includes env_init(). Try moving bi_ip_addr and bi_enetaddr
below the init_sequence loop.

I'm out-of-office so I can't work on a patch for a few days. If the
changes work, please submit a patch to Wolfgang -- or we can
work together off-line.

Regards,
--Scott

[U-Boot-Users] NIOS port at Stratix DevKit: distinctions between bdi and env

[Stephan Linz]

Hi Scott and all other NIOS people,

today I've successfully brought up and running the U-Boot NIOS port on a 
Stratix Development Kit (DK-1S10). Thanks to Scott -- was (is) a great work. 
The preconfigured Cyclone Edition was running and startup without critical 
problems, because as far as I know the Stratix edition is 100% equal to 
Cyclone except the FPGA.

But now, I can't setup my network environment in expected way. The u-boot 
environment vars "ethaddr", "iptable", "netmask", and "serverip" are correct 
in flash, but bdinfo shows me the default values (compiled in) -- Why ? 
(logfile see attachment)

Has anybody similar problems on Cyclone, or is it a Stratix problem (may be 
an useless question) ?

Where can I found the setup flow from saved environment to bdi structure 
inside the u-boot source code? I want to check up the settings step by step.


Ah: I'm using u-boot cvs snaphot date 20031024.

Thanks, and best regards

Checked in. May take a while until it actually shows up on CVS.

Just because your doctor has a name for your condition  doesn't  mean

Yes, of course.

Yes, that's the solution to my problem. I've moved the setup stuff of 
bi_enetaddr and bi_ip_addr far behind the whole init_sequence loop and the 
relocation env_relocate(). I think and hope, that will be save enough for the 
future development.

OK here is the patch (attechment). Wolfgang, could you put it into the CVS 
repository?
