Please make sure ICMP is enable

On Behalf Of Wolfgang Stich Hi I’ve a strange problem, I am using FreeRTOS 4.7.2 with lwIP 1.3.2 (or better I try to upgrade from lwIP 1.2.0 to 1.3.2) based on a AVR32. I am using AVR32 Software Framework and its sys_arch port. I’ll get a IP from the
dhcp server but I can’t ping the device (no reply). lwIP Stats show me, there have been some proterr occurred. Here are my lwIP Options: /*This file has been prepared for Doxygen automatic documentation generation.*/ /*! \file ********************************************************************* * * \brief lwIP configuration for AVR32 UC3. * * - Compiler: GNU GCC for AVR32 * - Supported devices: All AVR32 devices can be used. * - AppNote: * * \author Atmel Corporation: http://www.atmel.com \n * Support and FAQ: http://support.atmel.no/ * *****************************************************************************/ /* Copyright (c) 2009 Atmel Corporation.
