  • Dear:
    I use nxp keazn84,I use inside clock(without Crystal oscillator),my PCB is very small(no place for Crystal oscillator).
    in my software busclock is20MHz.I found some chip is not on 20MHz,my uart cannot
    communicate with my computer.My serial port baud rate is38400.
    NXP fae told me that I can use cyclone pro to calibrate my clock when burn program. How can I do it?
    Thank you!

    I hope that answers your question! If not, please let me know so I can find the right solution for you.
