We have transplanted the reference code of UART interrupt, and use UART to receive data. If the serial port tool of the upper computer sends more than 8 bytes at a time, the following data will not be received, and if more than 8 bytes are overrun, please kindly help to check the problem, thank you!
The original KW45 lpuart_interrupt_transfer routine is fine to test, but will be overrun after porting more than 8 bytes.
Hope you are doing well.
I apologize for the inconvenience this might cause you, but this product has not been released yet. Could you please contact the person that provided you this board?
