On Fedora27 compiling the code found in the tomu-sample repo causes the ELF to have the following details: No version information found in this file. Attribute Section: aeabi File Attributes Tag_CPU_name: "Cortex-M0+" Tag_CPU_arch: v6S-M Tag_CPU_arch_profile: Microcontroller Tag_THUMB_ISA_use: Thumb-1 Tag_ABI_PCS_wchar_t: 4 Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_align_needed: 8-byte Tag_ABI_align_preserved: 8-byte, except leaf SP Tag_ABI_enum_size: small Tag_ABI_optimization_goals: Aggressive Size Please note the Tap_CPU_arch. On OpenSUSE the following is shown: No version information found in this file. Attribute Section: aeabi File Attributes Tag_CPU_name: "ARM v6K" Tag_CPU_arch: v6K Tag_CPU_arch_profile: Microcontroller Tag_ARM_ISA_use: Yes Tag_THUMB_ISA_use: Thumb-1 Tag_ABI_PCS_wchar_t: 4 Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_align_needed: 8-byte Tag_ABI_align_preserved: 8-byte, except leaf SP Tag_ABI_enum_size: small Tag_ABI_optimization_goals: Aggressive Size This causes the development board to fail to initialise as it is the wrong CPU arch. There are other platforms (arch linux, macOSX) where they correctly emit armv6s-m for -mcpu=cortex-m0plus. Version of affected packages: cross-arm-binutils-2.31-1.1.x86_64 cross-arm-none-newlib-devel-3.0.0-2.5.x86_64 cross-arm-none-gcc8-8.1.1+r262873-1.3.x86_64 Reproduction: https://github.com/im-tomu/tomu-samples Follow the readme, or: git submodule init git submodule update make -C libopencm3 make -C usb_simple readelf -A usb_simple/usb_simple.elf -- You are receiving this mail because: You are on the CC list for the bug.
