TMS320C6748: Using ndk for udp connection in TMS320C6748 SYS/BIOS

Duoduo Cheng

Part Number: TMS320C6748

When I added the ndk library and called the api interface, there is an error. The error is as follows:

Description Resource Path Location Type
<a href="processors.wiki.ti.com/.../10234"> unresolved symbols remain udp_t C/C++ Problem
gmake: *** [all] Error 2 udp_t C/C++ Problem
gmake[1]: *** [udp_t.out] Error 1 udp_t C/C++ Problem

unresolved symbol NDK_sendto, first referenced in ./main.obj udp_t C/C++ Problem
unresolved symbol NDK_socket, first referenced in ./main.obj udp_t C/C++ Problem

what is the reason? If you have an existing reference routine, please let me know. Thanks.

Hello,

I suspect you need to add the NDK package to your cfg file:

var Ndk       = xdc.loadPackage('ti.ndk.config');
var Global       = xdc.useModule('ti.ndk.config.Global')

It may be good to start with one of our examples. They can be built into CCS projects by running the following commands:

cd C:\ti\pdk_omapl138_1_0_5\packages

pdksetupenv.bat

pdkProjectCreate.bat OMAPL138 lcdkOMAPL138 little nimu all dsp
