Hi Amit. This is a known issue with the compiler. See LP: #771832 at: https://bugs.launchpad.net/gcc-linaro/+bug/771832 The problem exists in all 4.6 based compilers. The work around is to change the kernel configuration and disable Device Drivers -> Sound card support -> Advanced Linux Sound Architecture -> ALSA for SoC audio support -> Build all ASoC CODEC drivers. -- Michael _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
