I am closer to understanding why I experience an error when building with the ARM errata switches. I believe it is related to 32-bit app support in my poky Linux 64-bit build (I add this to support vcgencmd and vcdbg 32-bit apps.) When I remove the 32-bit support, the build completes OK. As of now, adding the following seems to work fine to acheive this: TARGET_CC_ARCH_append += " -mfix-cortex-a53-843419 -mfix-cortex-a53-835769” Something in the following block seems to be the culprit.: # for vcgencmd and vcdbg 32-bit executable support in the OS image (comment out for -c populate_sdk) require conf/multilib.conf MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "armv7a" IMAGE_INSTALL_append += " vcgencmd lib32-glibc lib32-libgcc lib32-libstdc++ vcdbg rpi-setup \ “ I will post again when I have localized the build problem further. Maybe there’s some 64-bit vs. 32-bit build confusion going on, and the armv7a default tune switch for 32-bits is colliding with the errata switches. - Steve Pavao Korg R&D -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
