I used it for three years and everything was okay. All this time I used stm32f030 board (with external 8MHz quartz) . Until this time, it worked perfectly. 18 September 2019 successfully compiled. Yesterday and today - it is impossible to compile. When compiling, I changed only constants and try compile original project (18 September 2019 - compiled ok).

I really need to use an external quartz and use my STM32F030F4P6 board. If use for compile NUCLEO-F031K6 board or NUCLEO-F030R8 board without mbed-STM32F030F4 library ( https://os.mbed.com/users/mega64/code/mbed-STM32F030F4/ ) - external quartz does not work.

Help

Hi,

Could you add some more information: - compiler (Online, Mbed CLI GCC_ARM/IAR/..) - what is the error message from the compiler

Thanks, Pekka

Currently using Keil + mbed-STM32F030F4 library, and have no problems. This problem appeared recently in an online compiler, and only in online compiler. Not possible to compile any old projects using "mbed-STM32F030F4 library" in the online compiler.
