LAUNCHXL2-RM57L: Lwip somewhat works with a static connection and does not work with DHCP

Hello Christian,

I will take a look, and come back later.

Hi Christian
Sorry to keep you waiting on this - Brad Davis just reminded us of this pending issue. QJ has been tied up on a few other escalations. We will need some more time to get back to you on this. The combination of LWIP + Free RTOS is usually tricky IMHO.
Are you planning to use LWIP and Free RTOS for your final product implementation?

Yes our final product will use LWIP and FreeRTOS. I appreciate your continued assistance with this. A high priority/urgency would be greatly appreciated.

Thanks,

Christian

Thanks for the clarification. Do you have more details on your failure? Are you suspecting this to be an MPU setting issue or a networking /DHCP issue?
When you see the failure , are you seeing any data aborts etc that would point it to be an MPU issue etc?

Mukul,

I have been following the tutorial I mentioned in my post and the only two parts I have not gotten working are the MPU section and replacing the HL_sys_link.cmd file with the recommended one. I can't do the MPU section because it is frozen in my Halcogen file so I would have to make the changes manually. I am still working on the HL_sys_link.cmd file. Do you have a link to a working HL_sys_link.cmd file that was written for the RM57L? 

I have not seeing any data aborts. When I create a static connection I can see that data is being sent out with a sharktap but I can't see the packets in another computer using wireshark. Whenever I try creating a DHCP connection the code fails when I try to establish a connection. I assume that this is because of the problems mentioned above with setting everything up properly.

Hi Christian

Thanks for the additional information. It looks like we have Free RTOS working standalone (simple examples) , and we know LWIP works both static and DHCP mode standalone.

We have not tried testing them both together and now getting a bench setup to try this out. We will update you once we have this up and running on our side. 

May take us a couple of days and some debug effort.

Hi Christian,

I will attach my example code for freeRTOS and LWIP webserver which works on TMS570LC4357 HDK. It works for both static IP and DHCP.

This is working freeRTOS+LWIP (webserver) on TMS570LC43x HDK:
