RE: RE: problems starting JavaKit

Dear Bryan,

We are writing a small socket program (enclosed in mail) in C, which
does the following:

1. opens a socket
2. binds to a local address with any port

bind() function returns error code as 11. We are unable to fix this
problem. Can you please help us.

Source code:

void main()
{
    unsigned char bs;


	unsigned int result;
	unsigned int i;
    struct sockaddr address;
    unsigned char data1[100];
    unsigned char data2[100];
    unsigned int handle1, handle2;

    printf("DS80C400 Initialization \r\n");

    printf("About to individually do all inits...\r\n");
    printf("\r\nAbout to clear XSEG...");
    init_clearXSEG();
    printf("\r\nAbout to copy IVT...");
    init_copyivt();
    printf("\r\nAbout to init redirect table...");
    init_redirect();
    printf("\r\nAbout to clear system RAM...");
    init_clearSystemRAM();
    printf("\r\nAbout to do mm_init...");
    init_mm(RAM_START, RAM_END);

    init_km();
    printf("\r\nAbout to do ow_init...");
    init_ow(INIT_DIVISOR_14MHZ);

    init_network();

    //init_eth();
    printf("\r\nAbout to do init_sockets...");
    init_sockets();

    printf("\r\n");

    // let's print out a little version information...
    printf("DS80C400 Initialization Library Version %d\r\n",
init_version());

task_version());

Saurabh,

DTR is required to notify the loader that a binary segment load is complete.
