Posted on February 19, 2016 at 09:47After compiling the CubeMX generated Code (without any changes).
The Ethernet stack crashes if it receives many UDP-packages in a short time. (1000-10000 10Byte packages in a few ms)
Even after stopping the flood the interface never comes up again.
The interface only comes back again if I call ''static void low_level_init(struct netif *netif)'' (without creating the thread and semaphore again) or after a software reset.
This behaviour is really bad.
Could you help me?

Another error, which has nothing to do with the upper one, is (stm32f4xx_hal_conf.h):
&sharpdefine PHY_MICR_INT_OE ((uint16_t)0x0002U) /*!< PHY Enable output interrupt events */
It should be:
&sharpdefine PHY_MICR_INT_OE ((uint16_t)0x0001U) /*!< PHY Enable output interrupt events */
