This user’s guide describes how to use pfr application.

Command line interface#

pfr#

Utility for generating and parsing Protected Flash Region data (CMPA, CFPA).

pfr [OPTIONS] COMMAND [ARGS]...

Options

-v, --verbose#

Print more detailed information

-vv, --debug#

Display more debugging information.

--version#

Show the version and exit.

--help#

Show this message and exit.

erase-cmpa#

Erase CMPA PFR page in the device if is not sealed.

pfr erase-cmpa [OPTIONS]

Options

-p, --port <COM[,speed>#

Serial port configuration. Default baud rate is 57600. Use ‘nxpdevscan’ utility to list devices on serial port.

-u, --usb <VID:PID|USB_PATH|DEV_NAME>#

USB device identifier.

Following formats are supported: <vid>, <vid:pid> or <vid,pid>, device/instance path, device name.
<vid>: hex or dec string; e.g. 0x0AB12, 43794.
<vid/pid>: hex or dec string; e.g. 0x0AB12:0x123, 1:3451.
Use ‘nxpdevscan’ utility to list connected device names.
-l, --lpcusbsio <usb,VID:PID|USB_PATH|SER_NUM,]spi|i2c>#

USB-SIO bridge interface.

Optional USB device filtering formats: [usb,vid:pid|usb_path|serial_number]

Following serial interfaces are supported:

spi[index][,port,pin,speed_kHz,polarity,phase]
- index … optional index of SPI peripheral. Example: “spi1” (default=0)
- port … bridge GPIO port used as SPI SSEL(default=0)
- pin … bridge GPIO pin used as SPI SSEL
default SSEL is set to 0.15 which works
for the LPCLink2 bridge. The MCULink OB
bridge ignores the SSEL value anyway.(default=15)
- speed_kHz … SPI clock in kHz (default 1000)
- polarity … SPI CPOL option (default=1)
- phase … SPI CPHA option (default=1)
i2c[index][,address,speed_kHz]
- index … optional index of I2C peripheral. Example: “i2c1” (default=0)
- address … I2C device address (default 0x10)
- speed_kHz … I2C clock in kHz (default 100)
