Did somebody ever get the following error message:
/usr/lib/gcc/arm-none-eabi/7.1.0/../../../../arm-none-eabi/bin/ld: unrecognised emulation mode: cpu=cortex-m4 Supported emulations: armelf collect2: error: ld returned 1 exit status
The linker options are:
arm-none-eabi-gcc -Xlinker -Map=_build/nrf52832_xxaa.map -mthumb -mabi=aapcs -L /path/to/nRF5_SDK_11_0_0_89a8197/components/toolchain/gcc -T -mcpu=cortex-m4 -mfloat-abi=hard -mfpu=fpv4-sp-d16 -Wl,--gc-sections --specs=nano.specs -lc -lnosys -o .o
People that had the same problem, solved it, but did not post a solution:
answers.launchpad.net/.../253559
The target is a NRF52832
Setting -mcpu=blah
I get this note:

which enlists cortex-m4.
Any ideas?
