lwIP & Concerto

Has anyone heard any news on the the lwIP port or sample app for the Concerto?

Thanks.

Tim,

I'm attaching a ported version of lwip. It's not on controlSUITE yet, but I hope it will help. 

You will need to replace the MWare\third_party\lwip-1.3.2 directory with the included one. Make sure the enet_lwip project is placed in the appropriate directory (F28M35x_examples_Master).

5327.lwip.zip EDIT: Outdated File, see later post for updated version.

Let me know if you have any problems.

Hi Alvaro,

Thank you for the files. However, I am not able to build the project due to the following error:

Hi Alvaro,

I noticed that the included project uses codegen version 4.9.1, but I am using version 4.6.6 for TMS470 Code Gen which is the latest release. Is this the issue?

Thanks,

Tim

Tim,

Version 4.9.1 should be available if you check for updates on CCS.

You can also downgrade the codegen tool version by right clicking on the project->source->upgrade code generation tools version and set it to 4.6.6.

Let me know if that doesn't work.

Alvaro

Hi Alvaro,

My CCS auto update is not working, but I figured out how to do a manual update by manually pointing to the update web address, and was able to upgrade to Code Gen v4.9.1. I'm about to try the project you sent.

Thanks again.

Hi Alvaro,

I have built and ran the executable, and have not been able to get it to work, so I'm looking for more help.

Right now I'm testing using the Ping command from a laptop, and would like to see an echo response from the Concerto. I have made a few modifications to facilitate this.

In main( ), I added and changed:

    IP4_ADDR(&ipaddr, 192,168,1,10);

    IP4_ADDR(&netmask, 255, 255, 255, 0);

    lwIPInit(pucMACArray, ipaddr.addr, netmask.addr, 0, IPADDR_USE_STATIC);

And in lwipopts.h, I uncommented:

Tim,

By default, the program attempts to acquire an IP address through DHCP. If it is unable, it selects a default one. If you're connecting it to a router, it should come work out of the box. If you're using a direct ethernet connection to your laptop, it's slightly different. Which are you using?

Also, a very helpful feature is the serial terminal. If you open up the virtual COM port that comes up when connecting via the USB cable to the controlCARD, some debug messages are printed. In the default caese, it will print out the DHCP acquired IP address, or the default one, if it comes to that.

Try running it as it was and see if it gets an IP. Once you have that, you can both ping it or access the sample web server with any browser.

Alvaro

Hi Alvaro,

I got the sample app running. As my previous code showed, I was doing htonl twice. You guys are great. Thanks for sending this sample prior to official release!

Tim

No worries. Thanks for the update!

Hi.

I try to debug this lwip example with ccs 4.2.4.00033 (eval. 30-day license) and Sauris IsoPlus SAU510 JTAG emulator with latest drivers. The time passed from clicking "Debug Active Project" till "Run" button became available is over 10 minutes. Is it normally? I have to debug the project where lwip is just a part. This project was previously developed for Stellaris MCU under Keil software, but there are no Keil software for Concerto MCU. How to decrease the uploading and debugger starting time?
