Don't forget to pull from the rabbits repos (./repos pull) before doing what is said below.
To compile this, make sure you have the binutils-arm-none-eabi package installed (debian), so that everything is in your path.
Then, build the binaries using make.
This produces a .bin file that is to be used to feed QEMU, and a .elf file that has to be given as argument to gdb.
The vectors.s file contains the whole interrupt service routines entries as given in STMicro documentation (extracted from the pdf) but none of them but the reset do something else than a self loop.
The reset handler does nothing as of today, and the C entry point is __start function.
If necessary, you can add your own stuff in the reset handler prior to calling __start, and have __start call whatever you think necessary.
To launch a simulation in debug mode, run in one terminal:
./nucleo-f401re.sh -debug -gdb-server 1234 -nographic -components.flash-native.file-blob PATH_OF_CODE/test.bin -components.flash-boot.file-blob PATH_OF_CODE/test.bin
and in an other terminal:
arm-none-eabi-gdb test.elf -ex "tar rem :1234"
Now add your own test to this.
