Hi,
I am Patrick of Nayna networks.
( Board name DB-88E6318 and CPU type MIPS - 5KC )
Now I am trying to boot Linux 2.4.18 ( Marvell-Monta Vista Distribution. )
I am using NFS Root mount and it normally mounted as I posted it.
after that. problems are happen.
After nfsroot mounted , automatically init procedures in busybox are
executed.
I saw that there was some discussion between Atifa_Kheel@yahoo.com and
mips-org.
It's similar symtoms but not much help.
In attached screenshot, For debugging purpose, I put this kind of strings
like
==========================================
!!/dev/console!!
!!!! Inside find_next_zero_bit
!!!
good /dev/console
!!!! Inside find_next_zero_bit !!!
next_fd = 2 in fcntl<4>!!!! Inside find_next_zero_bit !!!
next_fd = 3 in fcntl
in do_execve /sbin/init
retval = 1
in do_execve /etc/init
retval = 1
in do_execve /bin/init!!!! Insid
e find_next_zero_bit !!!
Using ELF interpreter /lib/ld.so.1
!!/etc/ld.so.preload!!
==================================================
In busybox main routines, It tries to detect real console and reads the
inittab ( Nothing else just call rc.sysinit )
and inside rc.sysinit, just tries to mount proc ... ( and consecutively
necessary command are listed )
and after that suddenly crashed.
Anybody who have some tips, I appreciate in advance.
Regards
Patrick
ps] We tried gcc version 2.91.66 and 3.2.2 also. but same as upon.
