I recently migrated my product from MQX 4.0 on MK60DX256 to MQX 4.1 for chipset MK64FN. One of the issues I have encountered is that the UART0 is not transmitting the correct amount of bytes to receiver. For example, UART0 transmits 400 bytes to receiver and receiver gets 83 bytes. This never happened on my previous chipset running MQX 4.0. Is there something I am forgetting about like UART configuration, timing, etc? I have ITTYA enabled in user_config.h. Any help is appreciated.
