[Buildroot] buildroot file system: Kernel panic

[Thomas Petazzoni <thomas.petazzoni@free-electrons.com>]

Dear Rohit Kumar,

Would it be possible to avoid top posting, and instead use bottom
posting, as is the usage of most mailing lists? Thanks!

Ok.

Your configuration indeed looks appropriate in terms of toolchain.

However, the kernel part of the configuration looks weird: it refers to
the kernel configuration file
board/atmel/at91sam9260ek/linux-3.9.config. Are you building a kernel
in Buildroot, but not using it for your platform?

Also, please enable CONFIG_DEBUG_USER=y in your kernel, and pass
user_debug=31 on your kernel command line. This should give more
details about the userspace crash.

Best regards,

Thomas
