At the beginning, the rate variable was assigned a value of 19200, and the communication was normal during initialization. The third-party serial port tool was used, and the serial port was sent and received normally. Next, I re-assigned the rate variable to 115200 by online modification and repeated the above code. The following problem occurs (/* Implement default assert macro */). Is there a problem with the steps I take? Do NXP engineers give some support? Thank you
