I use a FRDM-K64F with MQX and RTCS for network communication. However the boards don't reply on ping commands from my PC. When sending data from the FRDM board the board sometimes reply on a ping but mostly don't. I use KSDK-1.3.
The same applies when I send a UDP packet to the FRDM board. The data is send from the PC (logged with Wireshark) but the FRDM board don't react on it, however when I send lots of data from the FRDM board, the board mostly see the received data.
Changing the priority of the RTCS task higher then the other tasks makes not difference.
Has anyone encountered this problem? Or has a solution, or any advice for this?
