Properly connection parameters (TMDSEVM6670L ethernet). Custom socket project

Hello again.

I've followed the thread and got some problems. Debug stops at the 

rSocket = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP );
            if( rSocket == INVALID_SOCKET )
            	printf("FATAL ERROR! SOCKET IS NOT CREATED \n");

And returns this in the console:

00000.000 llEnter: Illegal priority call to llEnter()
00000.000 llExit: Illegal call to llExit()

What's wrong with this thing? If i'm using only recieve section, it's working, but when i add send section, this error appears. Is that a memory configuration issue or i've just mistaked in the socket creation code?

BTW: you've refered me once to the MCSDK "Helloworld" example. But neither there nor there i've not found the socket creation mechanism. Certain projects Daemon-functions are using sockets, but there are no functions of initiating socket. I'm really confused about how i can combine simple project and the 

 thread project.

And the last question. Which port is good for the transmission? I've tryed many and the board says me, that all of them are unreachable.

Hi Taras,

I have used "hello world" NDK example code which receive the UDP packets and send back to the same IP address.

So, you can use the function "dtask_udp_hello" from "udpHello.c" then create socket to do that....

You can also change the port no as your wish.

Here, 7 is the port no...

Ex:

static void NetworkOpen()

{

   // Create our local server

   hHello = DaemonNew( SOCK_DGRAM, 0, 7, dtask_udp_hello,

                      OS_TASKPRINORM, OS_TASKSTKNORM, 0, 1 );

}

I have used packet sender to send UDP packets from PC (10.100.1.94) to C6678 EVM board (10.100.1.17) and able to get the same packet to my PC (echoed back).

I hope, that's what you need right ?

I have used the following code from C6678 hello world example.

int dtask_udp_hello( SOCKET s, UINT32 unused )
{
    struct sockaddr_in sin1;
    struct timeval     to;
    int                i,tmp;
    char               *pBuf;
    HANDLE             hBuffer;

    printf("########### UDP HELLO EXE ########### \n");

    (void)unused;

    // Configure our socket timeout to be 3 seconds
    to.tv_sec  = 3;
    to.tv_usec = 0;
    setsockopt( s, SOL_SOCKET, SO_SNDTIMEO, &to, sizeof( to ) );
    setsockopt( s, SOL_SOCKET, SO_RCVTIMEO, &to, sizeof( to ) );

    for(;;)
    {
        tmp = sizeof( sin1 );
        i = (int)recvncfrom( s, (void **)&pBuf, 0, (PSA)&sin1, &tmp, &hBuffer );

        printf("UDP PACKET RECEIVED from port 5555 : %p\n",*pBuf);

        // Spit any data back out
        if( i >= 0 )
        {
            sendto( s, pBuf, i, 0, (PSA)&sin1, sizeof(sin1) );
            recvncfree( hBuffer );
        }
        else

            break;
    }

    // Since the socket is still open, return "1"
    // (we need to leave UDP sockets open)
    return(1);    
}

It is the same for C6670 hello world application too.

Please let me know if any issues.

I have send UDP packet from PC to board through "packetsender" and captured the packet in PC which I received from board.

Well i thank you very much, that really helps a lot. But that's not all what i need to do. I've created C++ application, which must send a string like "Hello Board" to the board. Board must recieve this, and spit the "Hello PC" String. In my case it look like even the infinte cycle of recv with "break" is not helping, i can't recieve this data. If i will fix and understand that, hope i'll can do sending to PC by myself.

UPD: Program runs out of memory when i'm launching the C++ application. Problems with heap or something like that:

[C66xx_0] ti.sysbios.heaps.HeapMem: line 294: out of memory: handle=0xc1f00b0, size=4096

It's sad, but i can't increase the Heap size, because my programm is barely allocated with that configuration:

If you still remember my DDR3 problems, you would understand this "crutch" :) Still, i will try to add another internal memory region, such as L1DSRAM or something. Please, can you provide links to examples of ad sizes of memory regions and the regions themselves.

the Full picture of an issue:

Also, can you please link me your *.cfg file memory map allocation?

https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/client.7zOk, i will gladly send you my project.

Hi Taras,
Sorry for the delayed response on this.
I'm not able to find source files (*.c,*.cfg etc.,) in the attached project.
Can you please attach it with complete project.

This should be my project tree, which is contained in the archive, after import. I'm re-sending archive now.client.zip

Can i hope to receive news on Monday?

Hi Taras,
Thanks.
Now I'm able to see your memory insufficient issue.
You have added lot of stuff (platform LED code, testing etc.,) in that code which consume much memory, I will look into it and get back to you.

Hello again.

Well, i've really added a lot of stuff, but in the final stage, i will need to add the whole calculation program in the project, so it's critical to me to know if I can work within the framework of internal memory or will have to finish boot DDR memory. And i'm afraid that this will be a nessesary step, but now i would be satisfied with properly internal configuration.

UPD: Still working to make the DDR loader to initialize. Waiting for your news.

Hello Titus.

Your code helped! Thank you very much, i've defeated this simple project. I will still ask further  questions about DDR init in other themes, but this thing is finished

Yes, i was switching it off, doing the full reset, etc. Everything is worked, but one tiny thing appeared - when i'm receiving the data, it appears like

What should i do, if i want to print the whole data message, instead of only first letter? 

And one more thing? Are there the specific memory locations for ethernet buffer, or they are created dynamically? Can i allocate the specific one  to watch it?

This project is working correctly too. I've tested this, didn't find issues.
