TMS570LS0714: which file define the " _enable_IRQ()"

Hi,

The "__TI_VFPV3D16_SUPPORT__ " is defined by the compiler tool at compile time. You can see it being defined as part of the "Processor Options" in CCS.

Where did you see the call to the _enable_IRQ() function? HALCoGen generates an _enable_interrupts() function which is defined in the sys_core.asm file. The source code is very simple and uses a single instruction to clear the "I" and the "F" bits in the CPSR register to enable the CPU to respond to IRQ and FIQ exceptions.

Sunil,

If so why cannot found it in sys_core.asm?

This is question from customer, could you help to check the define place?

does it possible ,it it defined in compiler tools ?

Hello Huihuang,

1. The _enable_interrupt_ is defined in sys_core.asm, and it enables both IRQ and FIQ. Make sure to include sys_core.h in your C file that uses the assembly function.
2. The _enable_IRQ( ) is a compiler intrinsic function. You need to be compiling in ARM mode in order to use this intrinsic.
