STM32F407ZTE6 LwIP problem with DP83848 - does not ping

[Lghi.1]

hello every one,

I have one STM32F407ZTE board with DP83848 as PHY.

I want to use STM32cubeMX as initialization code generator.

STM32F4 version is 1.27.1. I try with and without RTOS v2, but I can get ping.

Hello,

Try to switch to MII mode (Since it's the default mode and maybe there's a HW rework to make to activate the RMII mode) and ensure that the default task stack size is sufficient (larger than 1024). Normally it should work.

Regards

Mahdy

Hi,
This solves the problem, it is necessary. (default task stack size is sufficient (larger than 1024).)

You could debug ethernet_link_thread to find is it a hardware/configuration problem or not.

and take a short look at my post about ETH on f407 and dp83848 couple https://community.st.com/s/question/0D53W00001sGiChSAK/cubemx-lwip-ethernetlinkthread-bug
