Network LAN

Post by donna » Sun Feb 02, 2020 12:02 pm

Hello all,

I am having trouble with using LAN. The function is available to me when using the REPL prompt and the network library.

However, when I call the function, my REPL shuts down and restarts. Using a custom auto clicker board with the LAN8720 chip, which is the same as on other STM32 boards that have working ethernet support.

Help would be greatly appreciated.

Thanks

Hi,

Any chance you can post a link to your custom board definition? It sounds like you're using the STM32 port?

Might be a tricky one to debug -- do have a way to debug that your custom board definitely has all the right connections for RMII?

Does your board expose SWD? Might be worth trying to do a debug build and use an st-link and find out where the crash is happening.

The LAN8720 is compatible with the LAN8742 right?
