First off - I am not the best person to answer these questions, as I
have never used a NIOS system. So please try to get help on the
mailing list that I cc'ed my last reply to. Someone there should be
able to have better answers to your questions.
One more thing though - from your description I am not sure what
version of U-Boot you are using and whether you were able _at all_ to
boot Linux on your system. The error messages below strongly leave me
to not believe this.

Why did you remove the other line from my patch? Obviously this is
the patch I suggested and the second line was in there because I have
seen that there is still another CPU type not implemented yet in
mkimage so one should try to fix this in one go. It does _not make
sense_ to throw out such things after the work it has taken to put
them in.

As you know from studying cmd_bootm.c the imi command _does not_ check
the compression type. The image type shows uncompressed so mkimage
should have put a 0 in the compression type field.

Yep, there are compression type 0, 1 and 2 but nothing else.
According to what I wrote above the compression field is boguos. Of
course you noticed reading the source for mkimage that it should have
put a 0 in it and now theres a 39 in there. It looks like the image
is corrupt for whatever reason - try using the debugger and a hexdump
program to find out at what stage this goes wrong.
And of course use U-Boot from CVS and _not_ U-Boot 1.1.1
Cheers
Detlev
PS: Mail f'up-to set _again_ to u-boot-users at lists.sourceforge.net.
You know of course from the netiquette, that it is considered rude
behaviour to ignore such hints repeatedly, don't you?
