You can use different triggers and arguments depending on what function you want to perform. Refer to the for more details on how to use different triggers and arguments.
Erasing, programming, verifying, and reading the flash memory
To perform the most common programming functions, you can use these triggers and arguments:
Trigger Argument Function --- --- --- -e N/A Erase flash memory -p [file name] Program flash memory with binary file -v [file name] Verify flash memory with binary file -r [file name] Read flash memory and save it as binary file For example, if you want to erase, program, verify, and read the flash memory of your target device with a file named test.hex, you can type these commands:
fet -e fet -p test.hex fet -v test.hex fet -r test_read.hex
These commands will erase the flash memory, program it with the test.hex file, verify that the programming was successful, and read the flash memory and save it as test_read.hex file.

Frequently Asked Questions (FAQs)
What is FET?
FET stands for flash emulation tool. It is a hardware device that connects to your computer via USB and to your target device via JTAG or SBW interface. It allows you to program and debug your target device using software tools like FET MSP430 Flash Programmer.
What is JTAG?
JTAG stands for joint test action group. It is a standard interface that allows you to communicate with your target device using four wires: TCK ( clock), TMS (mode select), TDI (data in), and TDO (data out). It allows you to program and debug your target device using software tools like FET MSP430 Flash Programmer.
What is SBW?
SBW stands for Spy-Bi-Wire. It is a proprietary interface that allows you to communicate with your target device using two wires: TEST and RST. It allows you to program and debug your target device using software tools like FET MSP430 Flash Programmer.
What is FRAM?
FRAM stands for ferroelectric random access memory. It is a type of non-volatile memory that can be used to store data and code in MSP430 devices. It has several advantages over flash memory, such as faster write speed, lower power consumption, and higher endurance.
What is BSL?
BSL stands for bootstrap loader. It is a feature that allows you to program your target device using a serial interface, such as UART, I2C, or USB. It can be used as a backup option if the JTAG or SBW interface is not available or damaged.
