    Hi William

    Connect KL720 uart0 , ubuntu command "lsusb" will show "ID 0403:6010 Future Technology Devices International, Ltd FT2232C/D/H Dual UART/FIFO IC"

    The com port name in ubuntu should be "ttyUSB0"

    d$ dmesg | grep tty

    [  0.062939] printk: console [tty0] enabled

    [  0.768034] 00:05: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A

    [  3.862863] usb 3-2: FTDI USB Serial Device converter now attached to ttyUSB0

    [  3.863635] usb 3-2: FTDI USB Serial Device converter now attached to ttyUSB1


    • So Set utils/flash_programmer/nand/setup.py

    COM_ID = 0 

    • Add the line to /etc/udev/rules.d/10-local.rules

    KERNEL=="ttyUSB*",ATTRS{idVendor}=="0403",ATTRS{idProduct}=="6010",MODE="0777",GROUP="dialout"


    After reboot ubuntu, uart port should be work.

    p@ubuntu:~/kneron/kl720_sdk/utils/flash_programmer/nand$ python3 flash_programmer.py -v fw_mozart_flash_programmer_auto_210130_nand.bin

    dev_init try...

    Uart port open ttyUSB...

    Device init successfully

    Please press reset button!!

    Reset done!!

    b'BOOT MODE: Manual'

    b'1. SPI-NOR'

    b'2. SPI-NAND'

    b'3. USB'

    b'4. UART(Xmodem)'
