Previously I use Poky-Dylan-9.0.2 and custom linux kernel 3.8.5 with Real Time patch 3.8.4-rt. Kernel works fine if it was compiled by GCC-4.5.3 (some very old OpenEmbedded) or GCC-4.7.2 (poky-dylan-9.0.2). At some moment I decided to upgrade onto Poky-Dizzy-12.0.0 or Poky-Fido-13.0.0, but encounter an issue with kernel operation. Kernel compiled by GCC-4.8.2 or GCC-4.9.2 simply does not work at all. No anyone message was printed at terminal after loading of kernel by boot-loader. To confirm issue, I intentionally compile same kernel source tree by hands with GCC-4.7.2 and it works fine. This is made by small script like following: PATH=$PATH:..../yocto-build-poky-dylan-9.0.2/tmp/sysroots/x86_64-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi "make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi-" Does somebody experience similar issues with kernel compiled by old and new compilers? Unfortunately I does not know a way how to resolve this issue with new compilers. Can you recommend how to resolve issue with compiler version in newest Poky? Best wishes. -- Igor Plyatov
