TARGET_STM32F303xC: SetSysClock() missing

[tmsick1990]

Description of defect

I generated a custom target DISCO_F303VC from STM (STM32F3DISCOVERY)
When i want to compile the code i get this error:

C:/projects/mbed-os/mbed-os/targets/TARGET_STM/mbed_overrides.c:286: undefined reference to SetSysClock' CMakeFiles/my-mbed.dir/mbed-os/targets/TARGET_STM/sleep.c.obj: In function hal_deepsleep':
C:/projects/mbed-os/mbed-os/targets/TARGET_STM/sleep.c:272: undefined reference to `SetSysClock'
collect2.exe: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.
ERROR: CMake invocation failed!

I have seen that inside the TARGET_STM32F303xC there is no system_clock.c file is that correkt?
Also i tried to compile it with the TARGET_STM32F303xE that has a system_clock.c and it works.
So what i have to do?

My custom_targets.json
{
"DISCO_F303VC": {
"inherits": [
"MCU_STM32F303xC"
],
"device_name": "DISCO_F303VC",
"core": "Cortex-M4",
"supported_toolchains": ["GCC_ARM"
],
"device_has_add": ["CLOCK_SOURCE_PLL",
"CLOCK_SOURCE_HSE"
],
"macros_add": ["HSE_VALUE=8000000",
"HSE_STARTUP_TIMEOUT=100",
"HSE_PREDIV_VALUE=1"
],
"extra_labels_add": ["STM32F303xC"
]
}
}

My mbed_app.json
{
"target_overrides": {
"DISCO_F303VC":
{
"target.clock_src": {
"help": "Clock source to use, can be XTAL or RC",
"value": "USE_PLL_HSI"
},
"target.clock_freq": {
"help": "Clock frequency in Mhz",
"value": "16",
"macro_name": "CLOCK_FREQUENCY_MHZ"
}
}
}
}

Right now I getting in touch with mbed os to start a whole project.

Target(s) affected by this defect ?

STM32F303xC

Toolchain(s) (name and version) displaying this defect ?

GCC_ARM

What version of Mbed-os are you using (tag or sha) ?

master

What version(s) of tools are you using. List all that apply (E.g. mbed-cli)

mbed cli 2

How is this defect reproduced ?

To reproduce the error you have to install mbed os CLI 2, and make a new project and then put the custom_targets.json and the mbed_app.json inside the projet and make mbed-tools compile -t GCC_ARM -m DISCO_F303VC.

Hi
I didn't verify if this is working, but you can check "old" code:
