CLOCK_SYS_UpdateConfiguration issue/defect

tommysvensson — Tue, 15 Nov 2016 07:44:08 GMT

Hi,

I'm writing a hardware initialization + application routine. And I want no interrupts during the init period so I call

INT_SYS_DisableIRQGlobal()

before init starts, and when init is finished I call

 INT_SYS_EnableIRQGlobal()

The problem is that during init

CLOCK_SYS_UpdateConfiguration()

is called. And that function enables global interrupt again. I think this is a bug and the behavior is not a wanted side affect.

The function is calling

__asm volatile ("cpsie i" : : : "memory");

instead of

INT_SYS_EnableIRQGlobal()

which respects nestled calls to global interrupt.

I'm using S32K144_SDK_gcc 0.8.1.

Hope this can be fixed in a new version of the sdk.
