Re: [microblaze-uclinux] booting to single user

[Guillaume.Gastebois@xxxxxxxxxxxxxxxxxxx]

Hello,

Thank you for answer. It was errors
in my init script (I wrote a script in init.d which launch two other scripts
in a jffs2 filesystem) : it deosn't find child scripts so it gives me single
user safe prompt. With mounted filesystem all works.
Great.

Please check your /etc/inittab -> there should
be line with agetty.
From my experiences this could be caused that you removed flatfsd program
but
your etc folder have some symlinks to folder which are fill with flatfsd.
If you
disable flatfsd program you should call make romfs image for generated
proper
etc config files.

It is not a bug it is standard u-boot behavior. U-BOOT
waits on packet but in
your tftp transfer your PC is sending another packets too which are not
related
with tftp. For example arps -> u-boot responses it too or IP. I believe
that
this features is possible to turn off. You can use ethereal for check which
packet cause it.
