Part Number: TMS570LC4357
Other Parts Discussed in Thread: TLK111, DP83640, HALCOGEN

Tool/software: Code Composer Studio

Hi,

I am trying to use lwIP and FreeRTOS in a project. I tried it manually with the guidance of sources below. Also, I searched lots of sources too.

https://processors.wiki.ti.com/index.php/HALCoGen_Ethernet_Driver_and_lwIP_Integration_Demonstration

Finally, I referenced your Support Teams advice project link in below:

https://e2e.ti.com/support/microcontrollers/hercules/f/312/t/799670?RTOS-TMS570LC4357-How-can-i-use-to-lwIP-at-RTOS

But I am getting error like below:

EMACRxINTSr and EMACTxINTSr are both defined in HL_sys_emac.c and HL_sys_emac.h also externed in HL_sys_vim.h

I also search similar issue in e2e to solve issue, I find a link below:

http://e2e.ti.com/support/microcontrollers/hercules/f/312/t/800324?CCS-TMS570LC4357-undefined-symbol-even-though-can-open-the-declarations

After I found it, I tried lots of things but nothing solved my problem. Please guide me with any solution.

Thanks for your attention,

Hello,

You mention that EMACRxINTSr and EMACTxINTSr are both defined in HL_sys_emac.c, but I don't see HL_sys_emac.obj as one of the object files passed to the linker. Is HL_sys_emac.c source file included in the project? If the functions/symbols are defined in that source file, then the file needs to be included in the build.

Yes, HL_sys_emac.c source file included in my project. I included it in my project source directory. I didn't understand the main reason of the problem.

I am attaching some of the snapshoots below. I think it will be usefull to express status detaily for clear explain.

My Versions:

Code Composer Studio : 8.3.0

HALCoGen : 4.7.1

HALCoGen EMAC Driver lwIP : v00.03.00

Run Time Support Library: TI v18.1.4.LTS

Thanks and Regards

In your first post, you mentioned:

"EMACRxINTSr and EMACTxINTSr are both defined in HL_sys_emac.c and HL_sys_emac.h also externed in HL_sys_vim.h"

In the screenshot, you highlight HL_emac.c. But I do not see a file named HL_sys_emac.c

So can you confirm if the symbols are defined in HL_emac.c?

If you would like us to confirm, please attach the following files (using the "Insert File" paper clip icon):
- HL_emac.c
- HL_sys_vim.c
- Build log - please do a Rebuild Project and save off the complete build log to a text file (as described here) and then attach the file here.

Sorry for missing information it is my syntax fault because of boiling brain. You are right there is no file like HL_sys_emac.c( it is HL_emac.c) or HL_sys_emac.h (it is HL_emac.h).

I attached desired files and my project directly. I also attached source code link in the below (If an error occurs while uploading a file). If we can run lwIP + FreeRTOS on TMS570LC4357 Launchpad HDK. We are aiming to apply UDP Multicast in a connected system in real-time with TMS570LC4357.

Since this project is based off an example provided by the Hercules team I will forward this thread to the experts there for their guidance.

Hi again,

I prepared a project that lwIP + Halcogen based and successfully builded. I have tried to ping to device to test everything is ok. Although, I follow official configuration steps on the HalCoGen side, system doesn't successfully pinging my Launchpad HDK. Any possibility for not pinging? Also, I have done debug the code to trace the issue. It is rising up in netif.c, it is being stuck in infinite loop.

Project (also my log Files and halcogen configurations snapshots):

3175.TMS570LC4357_lwIP_Q.rar

Links that I use for official configuration:

Hello,

Does the example in this link not work? You need to change the MPU setting for SRAM from cache write-back to cache write through.

When we directly download this example and include workspace it did not work. We are getting error like:

Unresolved symbol for below, (I include error logs )

EMACRxIntISR ./source/HL_sys_vim.obj
EMACTxIntISR ./source/HL_sys_vim.obj

When we have tried to configure MPU settings, its checkbox and configuration buttons grayed out for SRAM region (Region 3 Configuration). After, code side configuration has tried but does not work. (Before and after about code side configuration are below)
