next in thread | raw e-mail | index | archive | help
Hi,
I'm trying to boot a mikrotik routerboard RB435G (mainly a 433UAH with
256MB). I've setup a cross builded nfs root using 9-stable (head does
not works: interfaces does not come up).
I got the whole thing up until it nfs mount root filesystem. After that,
whatever dynamic binaries I invoke, it dumps core somewhere in libc.so.7
(always at same point). I guess it's libc since this is the last
accessed lib via NFS before crash.
I'm left with /rescue statically linked binaries that works well.
Any hint ?
(Cross compiled using: TARGET=mips, TARGET_ARCH=mipseb,
TARGET_CPUTYPE=mips32).
