# mbed-os-hardfp
|
|
|
|
This repository is a pinned snapshot of ARM Mbed OS for Beslan's Mbed OS 5
|
|
firmware projects.
|
|
|
|
Upstream source:
|
|
|
|
- Repository: https://github.com/ARMmbed/mbed-os
|
|
- Commit: `890f0562dc2efb7cf76a5f010b535c2b94bce849`
|
|
|
|
Local change:
|
|
|
|
- `tools/toolchains/gcc.py` uses `-mfloat-abi=hard` for `Cortex-M4F`,
|
|
`Cortex-M7F`, `Cortex-M33F`, and `Cortex-M7FD` in the GCC toolchain setup.
|
|
|
|
Reason:
|
|
|
|
- Existing TouchGFX projects link against hard-float libraries such as
|
|
`libtouchgfx-float-abi-hard.a`. The upstream Mbed OS 5 GCC settings emit
|
|
`softfp` for these cores, which causes linker ABI conflicts.
