Hello Robin,
you can use whatever build system you want to build your applications.
You can use pkgconfig to get the necessary flags for a particular BSP
installation.

I also had another question about a specific flag used when linking
RTEMS executables.
The link command for the example application is the following:
arm-rtems6-gcc -mthumb -mcpu=cortex-m7 -mfpu=fpv5-d16 -mfloat-abi=hard
-I=$RTEMS_INST/arm-rtems6/stm32h7/lib/include -MMD
-B$RTEMS_INST/arm-rtems6/stm32h7/lib -Wl,--gc-sections init.c.1.o
led.c.1.o stm32h7xx_nucleo.c.1.o -o blinky-test.elf -Wl,-Bstatic
-Wl,-Bdynamic -qrtems
Can anyone tell me the meaning of the -q flag? I did not find anything
by running arm-rtems6-gcc --help
This flag selects the right GCC specification for RTEMS. It is
necessary, just use it.
If you want to know how it works, you have to learn the GCC
specification format. For a start you can use "arm-rtems6-gcc -dumpspecs".
