Hello,
I was trying to run the HalGoGen 3.0 example : example_freeRTOSBlinky using a RM48 HDK.
I've followed the screens on HalCoGen help. AJusted the Include and compiler settings on my IAR and I got the following error :
"Error[Li005]: no definition for "_get_CPSR" [referenced from C:\Hercules\IAR\HCG_FREERTOS_BLINKY\Debug\Obj\os_port.o] "
I've tried to do a workaround.
I've added this code to the os_portasm.asm
-----------------------
;Get CPSR register
public vPortYield _get_CPSR
_get_CPSR
mrs r1,cpsr
bx lr
---------------------------
I also created a os_portasm.h and added the function stub:
#ifndef __OS_PORTASM__
#define __OS_PORTASM__
unsigned int _get_CPSR(void);
#endif
and included it on the os_port.c
There is any thing I'm missing ? is there some HalCoGen config that I've uset/not used that is messing up with the code.
Thanks,
Cristiano
