Assembly code in RTEMS C program on MVME162 VME CPU Board

[AJAI KUMAR MEDHAVI]

Hi


I am using RTEMS 4.10.2 with Windows Based MinGW. I wish to use following
Asssembly code within my RTEMS C application :


rtems_device_driver ISOADC_write(rtems_device_major_number major,
rtems_device_minor_number minor, void  *arg)
{

 ----
 ----

 asm volatile (" movea.l #$F0850010,%A1 ; "
				" add.l #2,%A1 ; "
				" move.w #2,(%A1) ; "
			   );

 ----

 ---

}


The program is getting compiled without error, but on linking it is giving
"undefined reference to F085010"


Then I tried following piece of asm code :


asm volatile (" move.l BaseAdd,%A1 ; "
  	      " add.l #2,%A1 ; "
	      " move.w #2,(%A1) ; "
	      " BaseAdd: dc.l		$F0850010 ";
);

then it is giving error on line " BaseAdd: dc.l		$F0850010 ";


Let me know exactly how to use following code in C file :


asm volatile (" move.l BaseAdd,%A1 ; "
  	      " add.l #2,%A1 ; "
	      " move.w #2,(%A1) ; "
	      " BaseAdd: dc.l		$F0850010 ";
);



OR


asm volatile (" BaseAdd equ  $FO850010;"
              " movea.l #BaseAdd, %A1;"
  	      " add.l #2,%A1 ; "
	      " move.w #2,(%A1) ; "
	      " BaseAdd: dc.l		$F0850010 ";
);


Thanks in advance.
