Hello,

Maybe you can help?

Thanks in advance.

The following is the data:

Board: EVMC6748 (I am using the TMS320C6748 DSP).

I am connected using the ethernet port to my router.

ccs: 5.4.0.00091

bios: 6_35_01_29

pspdrivers: 01_30_01

nsp: nsp_1_10_02_09

ndk: ndk_2_22_03_20

xdctools: 3_25_00_48

xgconf: I selected "global network settings", "http", "tcp", "ip" and enable IPv6.

The code builder makesa thread name "ti_ndk_config_Global_stackThread" - I verfied that the debugger gets to it.

Then it fails in the following piece of code:

hCfg = CfgNew();
if (!hCfg) {
xdc_runtime_System_printf("Unable to create configuration\n");
goto main_exit;
}

The entire function that is created by the code builder is given below:

/* Main Thread */
Void ti_ndk_config_Global_stackThread(UArg arg0, UArg arg1)
{
int rc;
HANDLE hCfg;

ti_sysbios_knl_Clock_Params clockParams;

/* Create the NDK heart beat */
ti_sysbios_knl_Clock_Params_init(&clockParams);
clockParams.startFlag = TRUE;
clockParams.period = 100;
ti_sysbios_knl_Clock_create(&llTimerTick, clockParams.period, &clockParams, NULL);

/* THIS MUST BE THE ABSOLUTE FIRST THING DONE IN AN APPLICATION!! */
rc = NC_SystemOpen(NC_PRIORITY_LOW, NC_OPMODE_INTERRUPT);
if (rc) {
xdc_runtime_System_abort("NC_SystemOpen Failed (%d)\n");
}

/* Create and build the system configuration from scratch. */
hCfg = CfgNew();
if (!hCfg) {
xdc_runtime_System_printf("Unable to create configuration\n");
goto main_exit;
}

/* add the Ip module configuration settings. */
ti_ndk_config_ip_init(hCfg);

/* add the Tcp module configuration settings. */
ti_ndk_config_tcp_init(hCfg);

/*
* Boot the system using this configuration
*
* We keep booting until the function returns 0. This allows
* us to have a "reboot" command.
*/
do
{
rc = NC_NetStart(hCfg, ti_ndk_config_Global_NetworkOpen,
ti_ndk_config_Global_NetworkClose,
ti_ndk_config_Global_NetworkIPAddr);
} while( rc > 0 );

/* Delete Configuration */
CfgFree(hCfg);

/* Close the OS */
main_exit:
NC_SystemClose();
xdc_runtime_System_flush();

}

Any idea?

Thanks in advance!!!

Actually it is worst:

i suspected that the problem is that my task is called before the network task starts, so I added a five sec delay in beginning of my task.

as a result the network task does start, but it gets to exit() which means my problem is even before...

Hi Gaby,

Looks like the task priority being set is too high. Network tasks cannot have a higher priority than the NDK's kernel priority, can you try lowering the tasks priority to 5?

It might also be good to take a look at section "3.1.2.2 Priority Levels for Network Tasks" and "3.1.2.3 Priorities for Tasks that Use NDK Functions" of the NDK User's Guide.

Thanks,

Hi, thanks for your reply, I found that quickly... actually there is a callback I shall use which indicates the ndk started and only then I can start my thread functionality.

Please note I updated the post, as the real problem was created when I corrected the priority issue - the initialization fails....

Any help will be appreciated!!!!

I paid attention I get this text in the debug console...

But I have pretty simple project...

Maybe I shall tool at the map file, do you know where is it?

If you have a direct suggestion how to correct it would be great....

00000.000 MAC Address = 00-08-ee-03-14-99

00000.000 EMAC should be up and running

00000.000 EMAC has been started successfully

00000.000 Registeration of the EMAC Successful

ti.sysbios.heaps.HeapMem: line 307: out of memory: handle=0xc005cea0, size=2048
xdc.runtime.Error.raise: terminating execution

Thanks

Hi Gaby,

Seems like the default BIOS heap size is insufficient for your application. Can you try increasing it within your .cfg file?

// Default heap size
// BIOS.heapSize = 0x1000;

// Larger heap size
BIOS.heapSize = 0x5000; // heapSize = 20480;

*You can increase or decrease as your application requires.

Thanks,
