Thanks guys，I resloved this problem already.The usb2uart chip cannot cover baudrate of 1000000，when I configured baudrate of hci_uart to 115200，it worked fine. 发自我的华为手机

This is your custom board, please verify that all UART lines, Tx, Rx, RTS, and CTS are wired correctly to your converter, correct buad rate and hardware flow control is used.

I have filed an issue related to HCI UART sample from zephyr running on nrf52832. I compiled the hci_uart sample successfully, but I am not able to use the UART interface through an external USB-UART

Hi Jiri, Welcome to awesome zephyr community. k_cycle_get_32() prints cycles. Use k_uptime_get(). Follow this to measure time : http://docs.zephyrproject.org/kernel/timing/clocks.html - PV
