LPC55S69: warning in SDK ?

EugeneHiihtaja — Fri, 27 Mar 2020 14:17:08 GMT

Hello !

I have this warning in SDK and it not looks so good.

../CMSIS/core_cm33.h:2353:32: warning: array subscript 4294967294 is above array bounds of 'volatile uint8_t[12]' {aka 'volatile unsigned char[12]'} [-Warray-bounds]
return(((uint32_t)SCB->SHPR[(((uint32_t)IRQn) & 0xFUL)-4UL] >> (8U - __NVIC_PRIO_BITS)));

How I can suppress it ?

Regards,

Eugene

Hi Eugene Hiihtaja,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
Before answering your question, I'd like to know more information about the phenomenon you mentioned, for instance, which demo in the SDK library you compile, which IDE you used, etc.

Have a great day,
TIC

Hi Eugene Hiihtaja,

Thanks for your reply.
I use the IAR to open a demo for testing, and the warning information doesn't raise out actually.
BTW, the SDK library is SDK_2.7.0.

Have a great day,

Hi jeremyzhou‌ !

I mean SDK2.7.1 and MCUXpresso IDE v11.1.1 [Build 3241] under Windows for be more precise.

Other compilers are separate story.

Regards,

Eugene

Hi Eugene Hiihtaja,

Thanks for your reply.
I also use the MCUXpresso IDE for testing, and the warning message doesn't raise out actually.
