mspm0flash

Linux tool to program a TI MSPM0 microcontroller. The tool programs and verifies the device memory through the I2C or UART interface. It communicates with the controller through the BSL (Bootstrap Loader).

Usage

Usage: ./mspm0flash [options] <CMD>

  Flash and verify firmware binary to a TI MSPM0L microcontroller.

  Options:
  -a, --address ADDR      Using given I2C_ADDRESS for communication
                          (default 0x48)

  -b, --baud RATE         Using given baudrate for communication
                          (default 9600)

  -I, --i2c  DEVICE       Using given I2C DEVICE for communication.

  -S, --serial  DEVICE    Using given serial DEVICE for communication.

  -n, --no-script         Do not execute init/exit script.

  -l, --length            Length of CRC to calculate.

  -s, --do-start          Start the application after programming.

  -v, --verbose           Increase verbosity, can be set multiple times.

  -V, --version           Display program version and exit.

  -h, --help              Display this help and exit.

  CMD:
    prog <fw-bin-file>   Program the firmware data.
    info                 Display the device info.
    erase                Erase the full flash.
    crc [<fw-bin-file>]  Calculate the CRC or read from device.

Program

The controller can be programmed though an I2C or UART interface.

mspm0flash -S /dev/ttyUSB0 -b 115200 -s -n prog <fw-bin-file>

mspm0flash -I /dev/i2c-8 -s -n prog <fw-bin-file>

Script

The script interface is used to prepare and exit the BSL.

The script has to be located under /etc/mspm0flash/ctrl. Alternative the script location can be override by setting the environment variable MSPM0FLASH_CTRL.

Example

#!/bin/sh

programming_mode() {
    # reset
    # set invoke pin
    # reset
}

normal_mode() {
    # release invoke pin
    # reset
}

case "$1" in
	init)
		programming_mode
		;;
	exit)
		normal_mode
		;;
