H7 device with one core needs ::M7

[zisi]

Describe the bug
I try to run the fetch-cube example but instead of use F4, I use H7. I got this:

Sources to reproduce

cmake_minimum_required(VERSION 3.16)
set(CMAKE_TOOLCHAIN_FILE ${CMAKE_CURRENT_SOURCE_DIR}/../../cmake/stm32_gcc.cmake)

project(stm32-fetch-cube C ASM)

stm32_fetch_cube(H7)

find_package(CMSIS COMPONENTS STM32H743VI REQUIRED)

set(PROJECT_SOURCES
    main.c
)

add_executable(stm32-fetch-h7 ${PROJECT_SOURCES})
target_link_libraries(stm32-fetch-h7 CMSIS::STM32::H743VI STM32::NoSys)
stm32_print_size_of_target(stm32-fetch-h7)

Steps to reproduce

1. mkdir build
2. cd build
3. cmake ..

Expected behavior
I expect to build by using make as step 4.

Additional context

@zisi
Please have a look at readme and mutlicore examples. As H7 family contains dual core devices you need to specify the core.

This code is working:

stm32_fetch_cube(H7)

find_package(CMSIS COMPONENTS STM32H743VI_M7 REQUIRED)

set(PROJECT_SOURCES
    main.c
)

add_executable(stm32-fetch-h7 ${PROJECT_SOURCES})
target_link_libraries(stm32-fetch-h7 CMSIS::STM32::H743VI::M7 STM32::NoSys)
stm32_print_size_of_target(stm32-fetch-h7)

@Hish15 We need to specify the core even on mono-core devices of the H7 family. Is this expected or should we handle it ?
If we handle it I suppose we should handle the _M7 variant also for mono-core devices? note it would be different of other pure mono-core families...

Thanks! Also i found a project, https://github.com/Hish15/DustSucker that helps me. Maybe in README could be added some projects that used stm32-cmake.

We don't really know projects using stm32-cmake but there are already some examples that should be enough to start with.
I plan to add some more/better H7 example as your question comes regularly.
