Rebuild BSP with IAR error

GaQuay — Fri, 27 May 2011 09:00:36 GMT

Hi,

I am trying to rebuild the bsp using IAR v6.0 and the compiler generates these of errors.

Error[Pe144]: a value of type "int" cannot be used to initialize an entity of type "unsigned int const volatile *"

The error points to this code

static uint32_t volatile * const pctl_ptr_arr[] = {
    &(PORTA_PCR(0)),
    &(PORTB_PCR(0)),
    &(PORTC_PCR(0)),
    &(PORTD_PCR(0)),
    &(PORTE_PCR(0))
};

I rebuilt the BSP on another machine (windows xp) and it compiled just fine.

Does any one have this same problem?

Hello,

I'm able to compile this with IAR 6.10.1:

static uint32_t volatile * const pctl_ptr_arr[] = {
    &(PORTA_PCR(0)),
    &(PORTB_PCR(0)),
    &(PORTC_PCR(0)),
    &(PORTD_PCR(0)),
    &(PORTE_PCR(0))
};

uint32_t volatile * port;
port = pctl_ptr_arr[2];

Do your macros PORTx_PCR() resolve to uint32_t volatile type? Maybe they are not known and compiler assumes int...

Regards,

PetrM

Thank for the hint. I will try to look into it. The message seems to point to what you suggested.

But just out of curiosity, I compiled this same piece of code using other machine, XP 32 bit, it works just fine.

Thanks I will post what I find out.

I have IAR 6.20.2 and on that compiller I get an error:

Error[Pe144]: a value of type "int" cannot be used to initialize an entity of type "unsigned long volatile *" C:\Program Files\Freescale\Freescale MQX 3.7\mqx\source\io\lcd\lcd_twrk40x256.c 71

The same for other 2 files from MQX. It is compiled just fine with IAR 6.20.1 and with CW10.1. Where can be the problem? How to fix it ?

There was a bug introduced in IAR 6.20.2. Download 6.20.3 and you should be good to go.
