RTOS/TM4C129ENCPDT: Looking for FreeRTOS based TCP or UDP functional project

Hello Sahil,

We don't have a FreeRTOS example for TCP for the EK-TM4C129EXL, but there is one for the DK-TM4C129X which can be found in TivaWare under [Install Path]\TivaWare_C_Series-2.1.4.178\examples\boards\dk-tm4c129x\freertos_demo

Not sure if that was one of the examples not for the LaunchPad you were mentioning. If you hadn't seen that before though, I'd give it a long hard look, as if you *must* use the LaunchPad, then at least you would only need to port that project to the LaunchPad MCU and Pinout. I think that would be a lot less work for you than trying to take one of our base TivaWare examples and add FreeRTOS to it (certainly can understand the concern about effort for such a task).

Hi thanks for your reply.

I am following the one you mentioned above. I am facing a problem in compiling it. The issue is exactly as mentioned in this post.

e2e.ti.com/.../588681

i.e.

Building the RTOS-Based Configurable Serial-to-Ethernet Converter on High Performance Microcontrollers Design Guide exactly as described in the document (TIDU951, dated April 2015) and receiving the following error:

"C:/ti/TivaWare_C_Series-2.1.4.178/third_party/FreeRTOS/Source/portable/CCS/ARM_CM4F/portmacro.h", line 144: error #18: expected a ")"
"C:/ti/TivaWare_C_Series-2.1.4.178/third_party/FreeRTOS/Source/portable/CCS/ARM_CM4F/portmacro.h", line 144: error #18: expected a ")"

2 errors detected in the compilation of "../config.c".  (along with numerous others)

References this line of code.

#if( configMAX_PRIORITIES > 32 )
#error configUSE_PORT_OPTIMISED_TASK_SELECTION can only be set to 1 when configMAX_PRIORITIES is less than or equal to 32. It is very rare that a system requires more than 10 to 15 difference priorities as tasks that share a priority will time slice.
#endif

Unfortunately It is not clear in the post, how the issue was fixed though !!
