core_cm55.h compilation correction

[lebihanm]

Hello,

I tried to compile the core_cm55.h and I found some compilation problem with gcc compiler.

The 2 problems detected are

1. __NVIC_PRIO_BITS not defined if the switch __CHECK_DEVICE_DEFINES is not defined. I would propose to add the declaration out side of the compilation switch, it won't generate any restrictions and could be defined in a seperate configuration file.
2. The type IRQn_TYpe is not defined => it could be declared in the file as
   /**
   \brief int32_t IRQn_Type definition. Add on top of official library.
   */
   typedef int32_t IRQn_Type;

Thanks

Regards

Hi @lebihanm,

the core header files, like core_cm55.h for Cortex-M55, are not intended to be used directly. The missing defines/types are expected to be provided by an enclosing device header file.

The device header files are typically shipped in the Device Family Pack (DFP) for your device. If you are using generic devices (no vendor specific peripherals) you can use the pseudo device header for Cortex-M55.

Let me know in case you have further questions.

Cheers,
Jonatan
