CubeMX ethernet of clean generated code chrashes (lwIP FreeRTOS STM32F4)

Question asked by di.lau on Feb 19, 2016

After 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?

uC: STM32F437IITx
PHY: DP83848

CubeMX 4.13.0 (Firmware Package for Family STM32F4 1.11.0):
   - [x] Enabled
   - [x] Enabled
- ETH:
   - Mode: MII
   - [ ] Activate Rx Err signal
- RCC:
   - High Speed Clock (HSE): Crystal/Ceramic Resonator
   - Low Speed Clock (LSE): Disable
   - [x] Master Clock Output 1
   - [ ] Master Clock Output 2
   - [ ] Audio Clock Input (I2S_CKIN)
- SYS:
   - Debug: JTAG (5 pins)
   - [ ] System Wake-Up
   - Timebase Source: TIM6
ETH_COL is sticked to pin PA3.

LWIP settings:
- IP_ADDRESS (IP Address):
- NETMASK_ADDRESS (Netmask Address):



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

It should be:
#define PHY_MICR_INT_OE                 ((uint16_t)0x0001U)  /*!< PHY Enable output interrupt events              */
