The port for arm-none-eabi-gdb is too old (7.12.1) to read the DWARF format generated by arm-none-eabi-gcc (12.2.0). Can someone please update the arm gdb to at least the version of devel/gdb (9.2)?
I know I can specify -gdwarf-2 when compiling my firmware, but libc and libgcc themselves contain newer DWARF and spoil the final binary for debugging. My current workaround is to strip debugging symbols from my libc and libgcc, but ideally the system would have a newer arm-none-eabi-gdb that's compatible with the other programs in devel/arm-none-eabi. I also tried to update the port locally to build from 9.2 sources, but the port patches didn't apply cleanly.
