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

[John Carter <mrjohndcarter@xxxxxxxxx>]

even though, it is somewhat of a new problem, I thought I'd post this
under the same thread, since I'm still working with the same hardware.

I've created a user application, basically "hello, world", using
printf, added it to the /user/ tree, and it seems to get built just
fine, but when I run it on the sh shell I get back:

pid X: failed 256

where X is an integer value that keeps increasing and increasing.

I've noticed this is happening with several other /bin programs:

typing "kill" gives:

BusyBox v1.00 (2004.11.17-01:49+0000) multi-call binary

Usage: ...

pid 68: failed 256

I'm guessing these programs are crashing, and this is just sash's way
of telling us, but I have feeling this is some omission on my part. 
It does with or without printf.  It does it returning void or int.

I looked around, but this is a tough one to search on.  Any ideas?

thanks,
jc
