enet_lwip not working on EK-LM3S9B92 anymore

Lubomir Bogdanov1

Hello, everyone!

I've recently updated my Code Composer Studio to v6.1.3 and downloaded StellarisWare for all MCUs, version 10636.
I import enet_lwip example and build the project (with TI v15.12.1.LTS). I debug it, I see the UART console displaying my IP but when I try to connect to the example web page - FAILS.

I flash the precompiled example with LM Flash - works perfectly.
What could be the problem in your opinion?

I can rebuild the enet_uip with that same compiler - and it works perfectly!

The target by default is LM3S9D92 ... tried to change it to LM3S9B92 - same, even worse - won't get an IP anymore.

Hello Lubomir,

The TI compiler version v15.12.1.LTS is something I haven't seen. And there was an issue reported similar to yours in the past with the same compiler version. I would suggest checking with Code Composer Forum.

I've managed to solve this problem the following way:
In CCS, right click your project -> properties -> Build -> ARM Compiler -> Optimization -> Optimization level: set it to Disable; Optimize for speed: set it to 0.

Hello Lubomir,

Thanks for posting back. BTW, please do note that LM3S products are EOL-ed and there would be sketch support at best.
