An error occurred Creating UART_Hwi

Hi,

I tried all the things to create a hwi for UART of EVM6678 but I failed yet.

From some articles here, I adopted many lines to try it.

Following code is what I tried finally.

-----------------------------------------------------------------------------

int UART_init(void)
{
    Hwi_Params UART_Hwi_params;
    Int hostInt, sysInt;
    int eventId;
    Error_Block eb;

//    platform_uart_init();

//    (void) platform_write_configure(PLATFORM_WRITE_ALL);

    hUartRegs->PWREMU_MGMT = 0x0;
    (void) platform_uart_set_baudrate(115200);

    hUartRegs->IER=0x01;
    hUartRegs->MCR = 0;
    hUartRegs->FCR = 0x7;
    hUartRegs->PWREMU_MGMT = 0x6001;

    sysInt = 148;
    hostInt = 32;

    eventId = CpIntc_getEventId(hostInt);

    Hwi_Params_init(&UART_Hwi_params);
    UART_Hwi_params.arg = hostInt;
    UART_Hwi_params.eventId = eventId;
    UART_Hwi_params.enableInt = TRUE;
    UART_Hwi_params.priority = 2;
    UART_Hwi_params.maskSetting = Hwi_MaskingOption_ALL;
    UART_Hwi_Handle = Hwi_create(5, UART_Rx_hwi, &UART_Hwi_params, &eb);
    an_error = Error_getMsg(&eb);

//    platform_write("UART_Hwi_Handle = %d\n",UART_Hwi_Handle);
//    Hwi_enableInterrupt(5);
//    Hwi_enable();

    /*
    * plug CpIntc dispatch table with 'UART_Rx_hwi'.
    * set 'unmask' to 'TRUE' to enable the system interrupt.
    */

    CpIntc_disableHostInt(0, hostInt);
    CpIntc_disableSysInt(0, sysInt);
    CpIntc_clearSysInt(0, sysInt);
    CpIntc_mapSysIntToHostInt(0, sysInt, hostInt);
    CpIntc_dispatchPlug(sysInt, UART_Rx_hwi, sysInt, TRUE);
    CpIntc_enableHostInt(0, hostInt);
    CpIntc_enableSysInt(0, sysInt);

    return 1;
}

-----------------------------------------------------------------------------

But when I printed the "an_error" in EVM_init() It was read as.  -- platform_write(an_error);

out of memory: heap=0xb, size=36123

In my .cfg file,

-----------------------------------------------------------------------------

var Memory  = xdc.useModule('xdc.runtime.Memory');
var Startup = xdc.useModule('xdc.runtime.Startup');
var BIOS = xdc.useModule('ti.sysbios.BIOS');
var Clock = xdc.useModule('ti.sysbios.knl.Clock');
var Hwi = xdc.useModule('ti.sysbios.family.c64p.Hwi');
var CpIntc = xdc.useModule('ti.sysbios.family.c66.tci66xx.CpIntc');

Clock.tickPeriod = 2000; 
//in usec

BIOS.heapSize = 65536;

var Task = xdc.useModule('ti.sysbios.knl.Task');

/* Configure the Modules */
BIOS.taskEnabled = true;

/* Create our memory map - i.e. this is equivalent to linker.cmd */
Program.sectMap[".const"] = "DDR3";
Program.sectMap[".text"] = "DDR3";
Program.sectMap[".code"] = "DDR3";
Program.sectMap[".data"] = "DDR3";
Program.sectMap[".sysmem"] = "DDR3";
Program.sectMap["platform_lib"] = "DDR3";

/* Lets register any hooks, tasks, etc that we want BIOS to handle
 ** Register an EVM Init handler with BIOS. This will initialize the   ** hardware.
** BIOS calls before it starts.
*/
Startup.firstFxns.$add('&EVM_init');

-----------------------------------------------------------------------------

I call UART_init() in the EVM_init() and it is the first thing in the EVM_init();

What is the meaning of "out of memory: heap=0xb, size=36123"?

and How to fix it?
