  -v, --verbose     Enable version debug message output.
  --read TEXT       Read from a file.
  --len INTEGER     Number of bytes to be read.
  --serialnumber    Get the device serial number.
  --list            List supported processors.
  --addr TEXT       Set the base address for the image.
  --verify          Read the device after programming.
  --verifyonly      Don't program, just verify.
  --eraseonly       Don't program, just erase. Implies --eraseall.
  --eraseall        Erase all flash not just the area written to.
  --blankcheck      Don't program, just check that the flash is blank.
  --filetype TEXT   Set filetype to intel hex format or raw binary.
  --bank INTEGER    Set filetype to intel hex format or raw binary.

  --mac TEXT        MAC address to associate IP address with.
  --help            Show this message and exit.How to Flash an NXP LPC MicrocontrollerUsing a USB to UART adaptor with both DTR & RTSNOTE: Development boards with USB to UART adaptors on them can skip these steps.Otherwise connect a USB to serial converter to UART port 0 on your device.
The USB to serial converter MUST have DTR and RTS support. An example of an
adaptor with all of the necessary pins isUSB to UART adaptor.Connect DTR to the chips RESET pin and RTS to the chips NMI pin.USB to UART adaptor without DTR or RTSIf you don't have a a USB to UART adaptor with both RTS and DTR but have some
way to control the RESET and NMI pin directly. Lets use a set of push buttons
as an example. Here are the steps:Hold down both RESET & NMI (pressing the button should short these signals to
ground)Release NMIRelease ResetDevice should be in bootloader mode now.To test this over a serial monitor, connect to the device using any baud rate,
recommended 115200, and send a single?character. The device should
respond with aSynchronizedmessage back.Flashing with NXPPROGThe general command for flashing a device with a binary looks like this:nxpprog --control --binary="main.bin" --device="/dev/tty.usbserial-140"--control: This will control the DTR and RTS pins in order to put the device
into bootloader mode, remove this if the device has been put into bootloader
mode in some other way.--binary="main.bin": path to the.binfile--device="/dev/tty.usbserial-140": path to the serial port file on your
system.Windows: COM1, COM2, etc..Linux: /dev/ttyUSB0, /dev/ttyACM0, /dev/ttyUSB1 ...MacOS: /dev/tty.usbserial-140, /dev/cu.usbserial-AC140J, ...
