RTOS/TMDSLCDK6748: NDK build error

Tom Pham84

Part Number: TMDSLCDK6748
Other Parts Discussed in Thread: OMAPL138, TMS320C6748, OMAP-L138

Tool/software: TI-RTOS

I'm using a TMDSLCDK6748  evaluation board and tried to create a program using the NDK features i.e. TCP/IP stack.

I'm using NDK 3.40.1.01 and SYS/BIOS 6.73.0.12.  I did added the NDK and SYS/BIOS under Project/Properties/CCS General/Products

I added to app.cfg-file the following:

var Tcp = xdc.useModule('ti.ndk.config.Tcp');
var Ip = xdc.useModule('ti.ndk.config.Ip');
var Global = xdc.useModule('ti.ndk.config.Global');

under Project/Properties/CCS Build/C6000 Linker/ File Search Path,  I added the following:

C:/ti/ndk_3_40_01_01/packages/ti/ndk/hal/eth_stub/lib/hal_eth_stub.ae674
C:/ti/ndk_3_40_01_01/packages/ti/ndk/stack/lib/stk.ae674

When I build the project, I got the following error:

unresolved symbol NIMUDeviceTable, first referenced in C:\ti\ndk_3_40_01_01\packages\ti\ndk\stack\lib\stk.ae674<nimu.oe674> VM_300M C/C++ Problem

I also tried to add this lib C:\ti\pdk_omapl138_1_0_6\packages\ti\transport\ndk\nimu\lib\omapl138\c674\release\ti.transport.ndk.nimu.ae674 but create a bunch of other errors.

I did read through the NDK user guide and search on TI E2E  but could not find any solution for my problem. Any help would be appricated. Thanks

    Hi,

    Since this is a BIOS project, you should have:
    var Nimu = xdc.loadPackage('ti.transport.ndk.nimu');

    in your .cfg file. Could you verify this?

    Best Regards,

    Hi Yordan,

    I added var Nimu = xdc.loadPackage('ti.transport.ndk.nimu'); to the app.cfg
    I also added to the #include search path the following C:/ti/pdk_omapl138_1_0_6/packages/ti/transport/ndk/nimu/package

    When build project I got this error:
    subdir_rules.mk:12: recipe for target 'build-1911590751-inproc' failed
    js: "C:/Tpham_WorkSpace/depot/MSS/VM-300M/Technical/Software/Code/devel_tp/DSP/app.cfg", line 25: xdc.services.global.XDCException: xdc.PACKAGE_NOT_FOUND: can't locate the package 'ti.transport.ndk.nimu' along the path: 'C:/ti/bios_6_73_00_12/packages;C:/ti/ndk_3_40_01_01/packages;C:/ti/xdctools_3_50_08_24_core/packages;..;'. Ensure that the package path is set correctly.

    I could not find the Nimu package under NDK or NSP directory . The only one I find is under C:/ti/pdk_omapl138_1_0_6/packages/ti/transport/ndk/nimu/package . Where is the nimu package located ?

    Another thing I did is adding this var Emac = xdc.useModule('ti.ndk.config.Emac'); to the app.cfg
    I could not find Ethernet driver under the NDK . So I download the NSP version 1_10_03_15 and linked to it using
    C:/Users/tpham/Downloads/nsp_1_10_03_15/packages/ti/drv/omapl138/lib/release/ti.drv.omapl138.ae674.
    When I build I do not see the unresolved symbol NIMUDeviceTable anymore but I got the following error:

    unresolved symbol EMAC_getConfig , first referenced in C:/Users/tpham/Downloads/nsp_1_10_03_15/packages/ti/drv/omapl138/lib/release/ti.drv.omapl138.ae674<nimu_eth.oe674> VM_300M C/C++ Problem
    unresolved symbol EMAC_initialize, first referenced in C:/Users/tpham/Downloads/nsp_1_10_03_15/packages/ti/drv/omapl138/lib/release/ti.drv.omapl138.ae674<ethdriver.oe674> VM_300M C/C++ ProbDescription Resource Path Location Type

    From what I understand that Emac module is used to link to Ethernet Driver. Where is Ethernet Driver for my TMDSLCDK6748 board located? I could find under NDK. Thus I have to download NSP version 1_10_03_15
    Do I need both Emac module and Nimu package?

    Is there a document, example or training video of what steps I have to do to configure/Initialize the Ether chip before I can create a TI-BIOS task/thread that do the socket(or NC_socket) open, bind, listen, accept

    Thanks a lot for your help.

    Hi Tom,

    The ethernet sources for OMAP-L138/TMS320C6748 devices are located in ~/ti/pdk_omapl138_1_0_7/packages/ti/transport/ndk/nimu. The ethernet driver is located in /ti/pdk_omapl138_1_0_7/packages/ti/transport/ndk/nimu/src/v6

    As for example/guide for the NDK, you can find the documentation here:
    software-dl.ti.com/.../index_Foundational_Components.html

    Also see the NDKA Api reference & driver design guide in: ~/ti/ndk_3_40_01_01/docs/ndk and the NDK User Guide: www.ti.com/.../spru523k.pdf

    Best Regards,
    Yordan

    Yordan,

    Thanks for information. I was able to resolve my problem after turn off the code generation option in the cfg file.
