 Peter> Then it's time to debug. Do you have an /etc/securetty on the target

 Robin> Yes, ttyS0 is listed in /etc/securetty. The only change i made

 Robin> busybox version and rebuild buildroot.

Peter> Ok, are you using the default busybox config
Peter> (package/busybox/busybox-1.13.x.config) or a custom one?

I'm using everything as default as set up by at91sam9263ek_defconfig. When checking
closer I realize the config file used is package/busybox/busybox-1.6.0. A diff
between this one and package/busybox/busybox-1.13.x.config gives a lot of differeces,
so I suspect this might be the cause of the problem. I'll try to recompile with a 
newer config file.

 Peter> If that's ok, then I would suggest you enable strace, boot with
 Peter> init=/bin/sh and send the strace output of running login here to the
 Peter> list.

 Robin> I tried passing init=/bin/sh to the kernel, but then I end up

 Robin> everything I type and produces newlines when I hit return but
 Robin> nothing more.

Peter> Strange, that doesn't sound right. What is you console= on the kernel
Peter> cmdline set to?

console=ttyS0,115200

Robin
