Hi, I am getting started with Arm Development Studio on Windows. I want to use the armclang compiler to target Cortex M4. I want to use CMake to configure the build and to work on the Windows platform.
Is there an example CMake toolchain file for this?Best regards
David
Hi David,Sorry, there are no CMake examples provided in Arm DS, but there are plenty based on Make.For example, the makefile for the "startup_Cortex-M4_AC6" example shows the basic armclang compiler options for Cortex-M4, e.g.:armclang -c --target=arm-arm-none-eabi -mcpu=cortex-m4 -mfpu=fpv4-sp-d16 -mfloat-abi=hard -O1 -g file.c(change -mfpu=fpv4-sp-d16 -mfloat-abi=hard to -mfpu=none if the (optional) FPU is not present)A typical link comamnd is also given, e.g.;armlink [list of objects] --scatter=scatter.scat --info=totals --info=unused -o image.elfHope this helpsStephen
Thanks for your reply Stephen,
Please will you explain:--scatter=scatter.scat
Thanks
Scatter loading is the mechanism used to define the memory map of the target device to the linker. See references below:
