Re: [microblaze-uclinux] pid X: failed 256 WAS: problems booting kernel

[John Carter <mrjohndcarter@xxxxxxxxx>]

thanks for the quick reply,  I've tried several different versions of
the program, using printf, and fprintf(stdin / fprint(stderr, and
tried return 0, and exit(0), but I'm still getting the pid X: failed
256 message.

that i'm not so worried about, but it may be related to the problem
I'm having: printf 'ing anything.  my program also has a scanf, but it
never reads anything either.

I'm still using the processor you sent me, I'm going to try to
resynthesize one tommorow, now that I have a working install on a
machine, but it strikes me as really odd that all the busybox stuff
(ls, cat, etc) will print just fine, and my printf stuff won't.  is
the system stuff using some special hook, and the processor you sent
doesn't have stdin, stderr attached?

or are there any other culprits I should look at?  

thanks for all your help,
jc
