I encountered some problems when using the MPC5744P uart communication routine. In the 'uart_echo_mpc574xP', I can receive a U8 element in the serial port 1 interrupt and output it to the serial port, but I want to transfer an array and adjust the receiving size to 10. The other did not make adjustments, but the program did not receive 10 elements and returned as I expected. May I ask where is the problem? Thank you!!
