Other Parts Discussed in Thread: HALCOGEN
Hi,
I am trying to remove MISRA C warnings of SCI(UART) Module. In halcogen I enabled SCI1 and I generated the code. I Could not remove the following required warnings. Please Help
1. (MISRA-C : 2004 1.1/R)Ensure strict ANSI C mode(-ps) is enabled
Above warning is showing in the following places
a) typedef signed char __int8_t; [ Warning from "_types.h" ]
b) typedef unsigned int uint32_t; [ Warning from "HL_errata_SSWF021_45_defs.h"]
2. (MISRA-C : 2004 10.3/R) The value of a complex expression of integer type shall only be cast to a type of the same signedness that is no wider than the underlying type of the expression
Above warning is showing in the following place
nmpu->MPUREGSENA = ((uint32)(config.regionsize)<<1U)|1U;
Here,
MPUREGSENA is defined as uint32
regionsize is defined as nmpuReg_t regionsize ;
typedef enum npuRegion
{
NMPU_REGION0 = 0U,
NMPU_REGION1 = 1U,
NMPU_REGION2 = 2U,
NMPU_REGION3 = 3U,
NMPU_REGION4 = 4U,
NMPU_REGION5 = 5U,
NMPU_REGION6 = 6U,
NMPU_REGION7 = 7U
} nmpuReg_t
3. The names of standard library macros, objects and functions shall not be reused(" exit ") [HL_sys_startup.c]
The following comments have been given. Please elaborate
/* SAFETYMCUSW 122 S MR:20.11 <APPROVED> "startup code (exit and abort need to be present)"*/
/*SAFETYMCUSW 354 S MR:NA <APPROVED> "startup code[Extern declaration present in the library)"*/
exit is declared as
extern void exit(int _status)
it has been called in the same programme as exit(0)
