Bring the headless Docker build closer to the official OpenGD77 build and
add a flashing helper.
docker/Dockerfile
- Replace Ubuntu's stock gcc-arm-none-eabi (GCC 10.3.1) with the Arm GNU
Toolchain 14.2.rel1 (GCC 14). The official firmware is built with GCC 14
(gnu-tools-for-stm32 14.3); GCC 10 produced a firmware that hard-faults on
the DMR path. Guard the image build to fail if the compiler is not GCC 14.
- git config --system safe.directory '*' so the build stamps a real GitID
instead of #UNKNOWN.
docker/build.sh
- rm -rf build before compiling. obj/ lives on the host mount and was being
reused across toolchain changes, silently relinking stale .o files (an
earlier rebuild produced a byte-identical GCC-10 image because of this).
docker/firmware.mk
- Add -DNDEBUG to exactly mirror the STM32CubeIDE "MDUV380_FW" release config
(which defines both NDEBUG and DEBUG).
flash.sh
- Helper to flash via opengd77_stm32_firmware_loader.py with model, secondary
language (auto-builds the .gla files) and the DMR codec donor.
.gitignore
- Ignore generated *.gla files and the host-side languages_builder binary.
Note: the GCC 14 rebuild did NOT resolve the DMR-receive hang; that fault is in
the firmware source revision (this tree is a snapshot; the known-good build is
commit ebd7100, not present here) and is out of scope of these build changes.
