Try this:

HWREG(NVIC_APINT) = NVIC_APINT_VECTKEY | NVIC_APINT_SYSRESETREQ;

Hi,

I have an error after using the "HWREG(NVIC_APINT) = NVIC_APINT_VECTKEY | NVIC_APINT_SYSRESETREQ;"

Description Resource Path Location Type
#138 expression must be a modifiable lvalue HFPDemo.c /HFPDemo line 554 C/C++ Problem

so, is there any problem? my hardware is tm4c123gxl.

Thank you~

Hello user4203513,

Did you include the file inc/hw_nvic.h in the code?

Yes, I did.

the error is "expression must be a modifiable lvalue" , dose it mean "NVIC_APINT" is unchangeable?

did i miss some settings?

I only added in the inc/hw_nvic.h but missed the hw_types.h where the HWREG() was defined.

Thank you~
