Hello,

I am trying to use the USB CDC device driver with an STM32F070. However, the usb console sample fails with the following error message (several similar errors shown, only one of them posted):

In file included from ../../../../../include/arch/arm/cortex_m/irq.h:17:0,

Steps to reproduce:

cd zephyr/samples/subsys/usb/console
mkdir build; cd build
cmake -GNinja -DBOARD=nucleo_f070rb ..
ninja

Anyone has an idea what I might have done wrong? If I compile for -DBOARD=arduino_101, everything works fine.

Thanks,

Martin
