Hi Jose, the cause of the HardFault can still be your port. You need to check your static initializers, i.e. constructors of the classes you initialize in global storage. Those will be executed before main() is called. Pay attention: the order in which those constructors are called is undefined.
Depending on your architecture the cause can be something not so obvious like unaligned memory access, so e.g. check dereferencing pointers.
