TMDSIDK437X: DHCP client verification

Hello Ronb,

I have gone through the section 6.4 of

https://www.ti.com/lit/ug/spru524k/spru524k.pdf?ts=1607626119067&ref_url=https%253A%252F%252Fwww.google.com%252F

ti_ndk_config_Global_serviceReport is assigned & i have kept breakpoint under ti_ndk_config_Global_serviceReport function but not hitting the breakpoint.

static char *TaskName[]  = {"Telnet","HTTP","NAT","DHCPS","DHCPC","DNS"};
static char *ReportStr[] = {"","Running","Updated","Complete","Fault"};
static char *StatusStr[] = {"Disabled","Waiting","IPTerm","Failed","Enabled"};
void ti_ndk_config_Global_serviceReport(uint32_t Item, uint32_t Status,
        uint32_t Report, void *h)
{
    DbgPrintf(DBG_INFO, "Service Status: %-9s: %-9s: %-9s: %03d\n",
            TaskName[Item-1], StatusStr[Status],
            ReportStr[Report/256], Report&0xFF);

}

i also gone through the section 2.1.4.1.2 of

https://www.ti.com/lit/ug/spru523k/spru523k.pdf?ts=1607657232354      

which mentions initIp() function from ndk.c but i didnt found initIp function so i added to my code under 

function "stackInitHook" which is getting called from global hook(start thread initialization hook).

Below is the code added under stackInitHook.kindl;ly consider dhcp related code.

void stackInitHook(HANDLE hCfg)
{
    CI_IPNET NA;
    CI_ROUTE RT;

    /* Add IP address for interface 1 */
    NA.IPAddr = inet_addr(ipAddr);
    NA.IPMask = inet_addr(ipMask);
    CfgAddEntry(hCfg, CFGTAG_IPNET, 1, 0, sizeof(CI_IPNET),
            (uint8_t *)&NA, 0 );

    /*
     * Add gateway for interface 1
     * --> I *think* the below should work but you may need different values ...
     */
    bzero(&RT, sizeof(RT));
    RT.IPDestAddr = 0;
    RT.IPDestMask = 0;
    RT.IPGateAddr = inet_addr(ipGateway);

    CfgAddEntry(hCfg, CFGTAG_ROUTE, 0, 0,
            sizeof(CI_ROUTE), (uint8_t *)&RT, 0);


    /*Add a configuration entry specifying the DHCP client service to be used*/
#if 1 | dhcp_client
 CI_SERVICE_DHCPC dhcpc;
 unsigned char DHCP_OPTIONS[] = { DHCPOPT_SUBNET_MASK };

#if 0 | already_added_ip_init
    static char *hostName = "tisoc";
    /* Add global hostname to hCfg (to be claimed in all connected domains) */
    CfgAddEntry(hCfg, CFGTAG_SYSINFO, CFGITEM_DHCP_HOSTNAME, 0,
    strlen(hostName), (unsigned char *)hostName, NULL);
#endif

    /* Use DHCP to obtain IP address on interface 1 */
    /* Specify DHCP Service on IF specified by "IfIdx" */
    memset(&dhcpc, 0, sizeof(dhcpc));
    dhcpc.cisargs.Mode = CIS_FLG_IFIDXVALID;
    dhcpc.cisargs.IfIdx = 1;
    dhcpc.cisargs.pCbSrv = &ti_ndk_config_Global_serviceReport;
    dhcpc.param.pOptions = DHCP_OPTIONS;
    dhcpc.param.len = 1;
    CfgAddEntry(hCfg, CFGTAG_SERVICE, CFGITEM_SERVICE_DHCPCLIENT, 0,
    sizeof(dhcpc), (unsigned char *)&dhcpc, NULL);
#endif

}

I have also added dhcp client related files from nettool folder.(C:\ti\ndk_3_61_01_01\packages\ti\ndk\nettools\dhcp)

below is the screenshot of workspace.

I have also called void netOpenHook() and void netCloseHook() from global hook.

under netOpenHook()  i have added DHCPOpen( pNTA , pNTP ) and under netCloseHook() i have added DHCPClose(hDHCP ); function.

below is the code.

/*
 *  ======== netHooks.c ========
 *  This file contains hook functions to start the send and recv threads
 */
 
#include <xdc/std.h>
#include <ti/ndk/inc/netmain.h>
#include <ti/ndk/inc/tools/servers.h>
#include <ti/transport/ndk/nimu_icss/example/src/osdrv_ndkdeviceconfig.h>


static HANDLE hEcho = 0;
static HANDLE hEchoUdp = 0;
static HANDLE hData = 0;
static HANDLE hNull = 0;
static HANDLE hOob = 0;
static HANDLE hDHCP = 0;

extern void ti_ndk_config_Global_serviceReport(uint32_t Item, uint32_t Status,
        uint32_t Report, void *h);


void netOpenHook()
{
    // Create our local servers
    hEcho = DaemonNew( SOCK_STREAMNC, 0, 502, dtask_tcp_echo,
                       OS_TASKPRINORM, OS_TASKSTKNORM, 0, 8 );
    hEchoUdp = DaemonNew( SOCK_DGRAM, 0, 7, dtask_udp_echo,
                          OS_TASKPRINORM, OS_TASKSTKNORM, 0, 1 );
    hData = DaemonNew( SOCK_STREAM, 0, 1000, dtask_tcp_datasrv,
                       OS_TASKPRINORM, OS_TASKSTKNORM, 0, 3 );
    hNull = DaemonNew( SOCK_STREAMNC, 0, 1001, dtask_tcp_nullsrv,
                       OS_TASKPRINORM, OS_TASKSTKNORM, 0, 3 );
    hOob  = DaemonNew( SOCK_STREAMNC, 0, 999, dtask_tcp_oobsrv,
                       OS_TASKPRINORM, OS_TASKSTKNORM, 0, 3 );
   NTARGS *pNTA;
   NTPARAM_DHCP *pNTP;
   unsigned char DHCP_OPTIONS[] = { DHCPOPT_SUBNET_MASK };
   pNTA->CallMode =0x0001;/*CIS_FLG_IFIDXVALID*/
   pNTA->IfIdx = 1;
   pNTA->pCb = &ti_ndk_config_Global_serviceReport;

   pNTP->pOptions = DHCP_OPTIONS;
   pNTP->len = 1;

   hDHCP = DHCPOpen( pNTA , pNTP );
}

void netCloseHook()
{

    DaemonFree(hOob);
    DaemonFree(hNull);
    DaemonFree(hData);
    DaemonFree(hEchoUdp);
    DaemonFree(hEcho);
    DHCPClose(hDHCP );

}

After this i am trying to debug but it fails below is the screenshot.

Kindly confirm the way of implementation is right.

Also help with debugg problem.

Regards,

Vrund
