Hardfault Exception on function return and IBUSERR

Hi Martin,

Thanks for dropping by.

The very first error that I encountered after setting up the simple LEDBlink project as pointed at the Yotta tutorial was: "Please select first the STM32F4XX device used in your application (in stm32f4xx.h file).

I downloaded the stm32f411re-nucleo-gcc as target and mbed-drivers as dependencies/modules.

So, I searched for fix on that error and I stumbled upon this link: Yotta and CMAKE not build - #3 by RoToRx88

It seems that this target is not supported yet, so I proceeded on trying to fix the error by myself.

I also did contacted the ST Micro guys and they said that they don’t have plan to migrate to Yotta and mbed-OS because they only support FreeRTOS (I have the email coming from our vendor), however, the Nucleo board, it says that it’s mbed-enabled.

Anyway, what else I need to do or to provide in order to get some suggestion or idea on how to fix my problem?

Thank you.
