There is not just big-endian on ARM. We have two variants BE32 (obsolete) and BE8. The Cortex-R5F processor supports only BE8, however, some TMS570 variants are BE32 internally. In GCC 8 and later, the --be8 option is passed to the linker based on the selected architecture or CPU. Use BE32 by default for the TMS570 BSP. --- spec/build/bsps/arm/tms570/grp.yml | 2 ++ spec/build/bsps/arm/tms570/optlinkflags.yml | 17 +++++++++++++++++ 2 files changed, 19 insertions(+) create mode 100644 spec/build/bsps/arm/tms570/optlinkflags.yml
