No, I always use FreeRTOS on STM32F107/207/217/407/417 , when PING response slow, SOCKET still working well .

On Behalf Of bernard It's better to open lwIP debug trace and add time stamp on each packet handling.
And Cui, you can try lwIP on RT-Thread with STM32F107/F207/F407. It has good stable on them.

Subject: Re: [lwip-users] ping issue This sounds like a driver bug. Are you using the stm32 demo code? It has this problem. The problem is that the interrupts are being lost but the packets are still there in the hw rx buffer. You need random rx packets to trigger new interrupts.
I posted some code recently that fixes this issue. On Jun 8, 2013 2:27 AM, "Vincent Cui" <address@hidden> wrote: All: A strange problem happen after device running some days.
After power on, PING response is fast. But after running some days, ping response becomes lower and timeout sometimes.
I configure ICMP checksum by hardware. Anyone has same problem ? Vincent Cui Firmware Engineer Leader Room1106, Building A, New Caohejing Business Centre, No.391, Guiping Road, Xuhui District, Shanghai, P.R.China T:
