vosamo007：Jelline大神，有个问题请教你啊。我在cc2538上移植contiki，下面这段程序报错
unsigned long __attribute__((naked)) //Error[Pe079]: expected a type specifier,Error[Pe141]: unnamed prototyped parameters not allowed when body is present
cpu_cpsid(void) //Error[Pe130]: expected a "{"
{
unsigned long ret;
/* Read PRIMASK and disable interrupts */
__asm(" mrs r0, PRIMASK\n"
" cpsid i\n"
" bx lr\n"
: "=r" (ret));
/* The inline asm returns, we never reach here.
* We add a return statement to keep the compiler happy */
return ret;
}
该怎么解决呢？
vosmo007，你好。我很长一时间没弄Contiki，手头也没有源码，你的问题，对现在的我很陌生，很抱歉。
