Hi,

I've added mcu_plus_sdk_243x via resource explorer.

I make call to the SDK functions but get "undefined reference" error.

How do I connect the SDK functions to my project , so it will be compiled together with my code ?

Thanks,

Eli

Hi Eli,

Please download the Am243x MCU+ SDK 08.06.00.45 from:

https://dr-download.ti.com/secure/software-development/software-development-kit-sdk/MD-ouHbHEm1PK/08.06.00.45/mcu_plus_sdk_am243x_08_06_00_45-windows-x64-installer.exe

then following the instructions from:

AM243x MCU+ SDK: Introduction

AM243x MCU+ SDK: Build a Hello World example (ti.com)

AM243x MCU+ SDK: CCS Launch, Load and Run (ti.com)

Best regards,

Ming

Hi Ming,

I did that with the CCS but I would like to bring the TCP server code example into my project.

Do I have to run the makefile included or do I have to link the example into my project and then compile all together ?

Thanks,

Eli

Hi Eli,

The easiest way to access TCP server API is to use CCS to import and build the TCP server projects:

C:\ti\mcu_plus_sdk_am243x_08_06_00_45\examples\networking\lwip\enet_cpsw_tcpserver OR

C:\ti\mcu_plus_sdk_am243x_08_06_00_45\examples\networking\lwip\enet_icssg_tcpserver

All the include paths for header file and library file are set properly. The syscfg file is also set up properly.

If you want to include the TCP server API into your existing application project, then you have to add the TCP server API header file, library file and the searching paths into your application project. The syscfg file has to be changed accordingly.

In general, all the library files (drivers, stacks etc.) are built using the makefile and the application code (using the APIs of libraries) are built using CCS projects.

Please refer to the above two CCS projects for TCP server API usage details.

Best regards,

Ming
