Thanks!

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 -- Thomas Petazzoni, CTO, Free Electrons Embedded Linux, Kernel and Android engineering http://free-electrons.com
