HI,

I upgrade to TIRTOS7 and get the IAR error

Error[Pe020]: identifier "GateAll_Params" is undefined C:\GitHub_Enterprise\int-visonic-PG-CC13xx-Platform\_source\common\eventQ\eventQ_private.h 102
Error[Pe020]: identifier "GateAll_Struct" is undefined C:\GitHub_Enterprise\int-visonic-PG-CC13xx-Platform\_source\common\eventQ\eventQ_private.h 103
Error[Pe020]: identifier "GateAll_Handle" is undefined C:\GitHub_Enterprise\int-visonic-PG-CC13xx-Platform\_source\common\eventQ\eventQ_private.h 104
Error[Pe020]: identifier "Error_Block" is undefined C:\GitHub_Enterprise\int-visonic-PG-CC13xx-Platform\_source\common\eventQ\eventQ.c 31

I add include of : #include <ti/sysbios/gates/GateAll.h>

And got :

Fatal Error[Pe1696]: cannot open source file "ti/sysbios/gates/GateAll.h" C:\GitHub_Enterprise\int-visonic-PG-CC13xx-Platform\_source\application\EcoSystem\_projectEcoSys_SIP\includTi_h_files.h 4

The file not in the folder .

My sysconfig define :

Where I can found definition of :

static GateAll_Params gateParams;
static GateAll_Struct gateStruct;
static GateAll_Handle gateHandle;

Hi Yaki,

GateAll is not present on TI-RTOS7. Have you considered using GateHwi?

Hi ,

Thanks for your replay .

Do you have migration instruction (Doc, Link ) ?

Hi Yaki,

We have this migration guide: https://dev.ti.com/tirex/content/simplelink_cc13xx_cc26xx_sdk_6_20_00_29/docs/ble5stack/ble_user_guide/html/tirtos/bios7_migration.html

But unfortunately it does not mention anything regarding GateAll not being supported in TI-RTOS7.

So ?

Can you get this information ?

Thanks

What specific information are you requesting?

GateAll is not supported in TI-RTOS7 so you have to use one of the other gates. GateHwi might be a good substitute, but you have to evaluate if it will be a good solution for your specific use case.

We are using with this code to protect on critical section :

init_function

{

GateAll_Params_init( &params );
GateAll_construct( &gateStruct, &params );
gate = GateAll_handle( &gateStruct );

}

user_function ()

{

//enter critical section
UInt gateKey = GateAll_enter( gate );

//critical section code

///exit critical section
GateAll_leave( gate, gateKey );

}

What is your recommendation to replace this code ?

Thanks in advance

This is from the documentation of GateAll:

GateAll uses disabling and enabling of interrupts, Swis and Tasks for the resource locking mechanism

This is from the documentation of GateHwi:

GateHwi uses disabling and enabling of interrupts as the resource locking mechanism.

I don't know if it is necessary to disable/enable Swis and Tasks in your application or if it is sufficient to only disable/enable interrupts. If you determine that using GateHwi is sufficient, then you can basically just replace GateAll with GateHwi in your code.

Thanks I also read it ,

What is the recommendation from TI to equivalent action to GateAll (Include Swis and Tasks) ?

Thanks

Below you find the implementation of GateAll_enter and GateAll_leave (in TI-RTOS6)

/*
 *  ======== GateAll_enter ========
 */
IArg GateAll_enter(GateAll_Object *gate)
{
    if (gate->entered == TRUE) {
        return (1);
    }
    else {
        gate->hwiKey = Hwi_disable();
        gate->swiKey = Swi_disable();
        gate->entered = TRUE;
        return (0);
    }
}

/*
 *  ======== GateAll_leave ========
 */
Void GateAll_leave(GateAll_Object *gate, IArg key)
{
    if (key == 0) {
        gate->entered = FALSE;
        Swi_restore(gate->swiKey);
        Hwi_restore(gate->hwiKey);
    }
}

So to achieve the same you can do the following in your scenario:

user_function ()
{
    //enter critical section
    intptr_t hwiKey = Hwi_disable();
    intptr_t swiKey = Swi_disable();

    //critical section code 


    //exit critical section
    Swi_restore(swiKey);
    Hwi_restore(hwiKey);

}

Nikolaj
