undefined reference to 'asm'

Hello everyone,

I'm trying to switch a project that worked in CW_IDE 10.6 to KDS beta and I have the following error that I cannot find an explanation for:

" undefined reference to 'asm' "

It comes from the usb stack 4.1.1 in a ProcessorExpert component with a USB_lock() and USB_unlock() define that is like this:

#if (defined _MCF51MM256_H) || (defined _MCF51JE256_H)

#include "usb_lock.h"

#define USB_lock() usb_int_dis()

#define USB_unlock() usb_int_en()

#else

#ifndef _MK_xxx_H_

#define USB_lock() asm { move.w SR,D0; ori.l #0x0700,D0; move.w D0,SR; }

#define USB_unlock() asm { move.w SR,D0; andi.l #0xF8FF,D0; move.w D0,SR; }

#else

#ifdef __CC_ARM

#define USB_lock() __disable_irq();

#define USB_unlock() __enable_irq();

#else

// I actually end up in this define

#define USB_lock() asm(" CPSID i");

#define USB_unlock() asm(" CPSIE i");

#endif

As I said, it use to work in CodeWarrior now seems KDS as troubles with assambly calls. Is there something special to do to support ASM calls in KDS? I find it really odd, even if I compare the Project Properties, in the Assembler portion, I don't see major differences from CodeWarrior settings to KDS ones. Could it be that I'm missing an ENV variable or a PATH variable that points to support for such assambly calls?

Please advise, thank you very much!

Mike

Hello Michel:

This problem is mentioned in Kinetis Design Studio FAQs (under Building):

KDS Frequently Asked Questions (FAQ)

The error is related to language settings. You may also refer to other thread about this:
