Re: [lwip-users] change PHY and strange behaviour

[George Ruinelli]

Hi pcu

I am also using the LAN8720 in RMII, together with an STM32F4 and FreeRTOS.

I also had an issue with lost packages. That was solved by a patch provided in 
this list.
Have a look at the thread at 
http://lists.gnu.org/archive/html/lwip-users/2013-09/msg00025.html

With this fix lwIP works without any issues.

Hope that helps.
