Nx_webserver example doesn't work on Nucleo-F429zi

[carlosdelfino]

Resuming studies, regarding:

I'm resuming my STM32 studies, having not used them for a few months.

After this time, and updates to CubeID and CubeMX, I'm trying to get back to it using the Nx_webserver example. Although the code appears to be correct, it doesn't work; it doesn't even get a valid IP address in DHCP.

I've tried changing the MAC address, but even then, nothing in DHCP works.

Is there anything I should do to make it work?

I have the following console output:

      -------------------------------------------------------------------

This error is happening when I load the project into CubeMX for the first time.

Hello @carlosdelfino,

Did you install your F4 firmware in a location other than the default one? Have you tried removing both the project and the firmware, then reinstalling them in the default location?

Regarding the DHCP issue, have you ensured that a DHCP server is running on your computer? If not, you should connect the board directly to the router so it can be assigned an IP address. Additionally, have you tried monitoring the network traffic using a tool like Wireshark? This can help determine if the DHCP sequence stops at a certain step or does not occur at all.

Best regards,

Hello, thank you for your attention.

I've already tried removing and creating the project, but I always get this error. I'll try removing the firmware and reinstalling it. I'll also try removing everything and reinstalling everything. I use Linux and have never had similar problems. Strangely, the compilation works, but the code seems empty in terms of the example's purpose.

I'll get back to you later today.
