I'm trying to upgrade an existing PCB (so changing the MCU is not an option for now).
The MCU used so far is the STM32f070F6. The MCU has USB peripheral and I want to use this as VCOM.
When I generate the code with CubeMX and try to compile (with absolutely no code change), I get the message that the MCU do not have enough RAM: "/arm-none-eabi/bin/ld.exe: region` RAM 'overflowed by 1760 bytes".
I have already changed the CDC buffers to a size of 40 bytes (maximum of what I want to transfer), but I still have a similar error.
Is there an example with this MCU in which the USB peripheral is used?
