I have an example application for my target hardware (ATMEL EVK1100 / AT32UC3A0512) which runs the lwIP stack in a FreeRTOS task.
I tried to activate DHCP for my application. This seems to work fine. At least I can obtain an IP address from the DNS. The problem is that it only works as long as the task priority is set to 7 or 8 (maximum is configured to 8). With lower priorities a ping to the given address stays unanswered. The high priority has the bad effect of starving my other tasks.
Has anybody an idea what problem I am facing? Similar experiences?
Thanks for your opinion. Regards,
