AM4376: tcpecho example and sntp

Vrund,

1) You can start from processor_sdk_rtos_am437x_6_03_00_106\demos\rtos_template_app project and then add the tcpecho server example described in NDK API user guide section 5.4.2 Server Daemon Example to the project.

2) \ndk\nimu is based on CPSW whearas the nimu_Icss is based on ICSS_EMAC.

3) You can integrate the tcpecho into the EIP.

4) Essentially you can use one of the methods below

1. You want to use default NTP servers (SNTP_getTime(), with a NULL server list)
2. You have the string names of one or more NTP servers (SNTP_getTime(), with your server list)
3. You have the sockaddr of the NTP server (SNTP_getTimeByAddr(), with your sockaddr)

as explained in file:///C:/ti/ns_2_40_01_02/docs/ns/html/group__ti__net__sntp__SNTP.html#details to the EIP project.

Regards,

Garrett

Hello,

1) You can start from processor_sdk_rtos_am437x_6_03_00_106\demos\rtos_template_app project and then add the tcpecho server example described in NDK API user guide section 5.4.2 Server Daemon Example to the project.

-- I have created the project and add demon.c  example provided "C:\ti\ndk_3_40_01_01\packages\ti\ndk\nettools\daemon" but it is not getting build. below is the build log.

Do you have netmain.h's directory (ti\ndk\inc) included?

Regards,

Garrett 

Yes.

netmain.h directory is included in deamon file.(#include <netmain.h>)

I have created project NIMU_ICSS_BasicExample_iceAMIC110_wSoCLib_armExampleproject

I can see nethook.c file is already added.

and it has 

void netOpenHook()
{
// Create our local servers
hEcho = DaemonNew( SOCK_STREAMNC, 0, 7, dtask_tcp_echo,
OS_TASKPRINORM, OS_TASKSTKNORM, 0, 3 );
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 );
}

void netCloseHook()
{
DaemonFree(hOob);
DaemonFree(hNull);
DaemonFree(hData);
DaemonFree(hEchoUdp);
DaemonFree(hEcho);
}

which file can i add tcpecho code from NDK API user guide section 5.4.2 Server Daemon Example to the project?

Regards,

Vrund

You need to include the path (ti\ndk\inc) in your project build 'Directories'. Currently you only have  -I"C:/Users/vrund rana/workspace_v7/rtos_template_app_am335x_a8" -I"C:/ti/gcc-arm-none-eabi-6-2017-q1-update/arm-none-eabi/include"

Hello,

I have added inculde folder in project dirctory.

hello,

Gentle Reminder.

Regards,

Vrund

It doesn't seem you have NDK library linked in your project build. Please refer to a NIMU example project in the PDK to see how NDK modules are included in the .cfg file, e.g. packages\ti\transport\ndk\nimu_icss\example\am335x\armv7\bios\am335x_app_icev2_wSoCLib.cfg

Regards,

Garrett

Hello,

I have added ndk library as below mention in ndk guide.

1.6.1 Adding NDK Support to an Existing Application If you have an existing application that has SYS/BIOS and XDCtools support, but does not have either TIRTOS or the NDK enabled, follow these steps to enable the NDK and NSP: 1. Right-click on the CCS project in the Project Explorer view. Choose Show Build Settings from the context menu. 2. Select the General category in the Properties dialog. 3. Go to the RTSC tab. 4. Check the boxes next to the most recently installed versions of the NDK and NDK Network Support Package products. 5. Click OK. 6. Reopen the *.cfg file in the project with XGCONF. The NDK and NSP should now be listed in the Available Products view if you expand TI-RTOS > Products. 7. Select the NDK > Global item in the Available Products view. Right-click on the Global module and select Use Global. You will see the Welcome sheet for NDK configuration. This sheet provides an overview of the NDK, configuration information, and documentation for the NDK. 8. Click the System Overview link at the top of the Welcome sheet to see a handy diagram of the NDK modules you can configure. 9. Right-click on the Emac module in the System Overview diagram and choose Use Emac. To configure the Emac module, select the device for which you are building. The Emac module will attempt to load the Ethernet driver for that device. If the device you are working with is not in the list, choose "NONE" as the device. In this case, you must link in your device's

Ethernet driver yourself. 10. Open the project's Properties dialog and go to the Build > Compiler > Include Options category. Add ${NDK_INSTALL_DIR}/packages/ti/ndk/inc to your application's compiler include path.

but still i am getting error.
