MCU-PLUS-SDK-AM243X: lwip examples: no IP assigned to LP

Belal Elmorsy

Hello,

I am trying to run the lwip examples, e.g., enet_lwip_cpsw, on the am243. I followed the setup in the docs and I set up a LAN for my host machine and the LP but the LP does not get an IP assigned from the dhcp server on the router.

here are the logs I get when running the enet_lwip_cpsw example:

then it keeps logging the CPU load.
